Jeep Wrangler Exhaust Upgrade Flowmaster How To Install Great Sound! 

Here's a link directly to the Holley webpage for this kit www.holley.com/products/exhaust/exhaust_systems/flowmaster/american_thunder/parts/817674

So funny to watch this old video now after following your channel for so long. Your plans for keeping the Jeep “basic” hilarious in retrospect.

Awesome video! We are glad to hear that you are liking the new sound of your Jeep. -Team Flowmaster

Says he's going to keep the build pretty "practical"... a few videos later tears off fenders, cuts body and shoves 37's on an unlifted jeep and goes off-roading haha! I can't blame you though I'm dealing with those same urges right now as I just bought my first Wrangler a few weeks ago. Sub'd.

One of the best sounding Jeep exhausts I've heard. Others I've heard just sounded like a long drone, on acceleration.

I just put front and rear flares on my '08 JK a couple weeks ago, and also chose the American Thunder exhaust and am installing it over the this Labor Day weekend. Can't wait to hear the sound upgrade! Thanks for showing how easy the install is without a hoist- that's what I was worried about. AWESOME VIDEO BUDDY!

I just did this install on a 17 Rubicon JKU. Just a heads up for anyone that is going to undertake this, a sawzall is your friend. It's almost like Chrysler doesn't want you to change out the sound and performance. The Flowmaster sounds great though.

I totally agree. Driving a manual makes you more aware. Awesome keep

Thanks for the video! I just installed this same Flowmaster exhaust on my 2014 JKUR. It sounds amazing when you're accelerating, but its very quiet while cruising. Exactly what I was looking for! FYI to anyone that is looking to purchase this: I had to either cut a small rivet off of my "Y" pipe or saw off an inch of the tubing to fit this exhaust in the way it is supposed to be. Just do yourself a favor and have either a hacksaw or dremel with a metal cutting wheel handy.

Great install video! I've approached my 2013 two-door manual Rubicon the same way. Part of the reason I was attracted to Jeep is because it still offers a manual. But, yeah, it was too quiet and I couldn't hear what the engine was doing. I am a sports car enthusiast but I also love off-road vehicles. Within a week of getting the Rubicon I installed an aFe 2.5 high-tuck system and an aFe Momentum intake (sorry Mangnaflow), and I also installed a Sprint Booster to change the throttle response. The Sprint Booster is an expensive little piece of plastic, but it radically improves the Jeep's driving dynamics. My Rubicon has better throttle response than my souped-up Sprint Booster-equipped MINI Cooper. I keep the Jeep in Red "race mode" all the time as it's way more sporty; I can actually blip the throttle when downshifting, which seems crazy for a Jeep. It takes a few drives to re-learn the gas pedal, but going back to stock feels like driving through molasses. Highly recommended as you develop your project. All the best.

I don't normally leave comments but when I do, its for people who deserve it! Great recording skills, not shaky or so close to the part that you can't make out what the part is. Oh and of course.... great choice in exhaust and mod!! Sounds like angels singing lol

I've had a Jeep my whole life. My dad had one when we was kids, mom had Jeep Cherokee. Always had one in my family. I've got a 2016 4 Dr Wrangler now and was wandering about putting flowmasters on it. I'm inspired now...... Oh yeah also, all jeeps ride like a damn heard of goats lol. I take my truck on long trips

any other stick shift wrangler drivers out there besides me and +autoedit ?

Wow! I want this on my Jeep! This is now on my to-do list before next summer :)

LOL, I did the same thing I'm getting rid of my 2001 Lifted WJ well loaning to my GF in Chicago till she gets here. Love my WJ and I to used an Iron Rock Off Road kit but in 6 1/2 inch. So by accident I also got a 2013 Jeep Wrangler Unlimited Sport. And already looking forward to building it. And yes the JK has tons and tons more aftermarket support. Great vids keep em coming.

The last seconds of the clip was just what I wanted to see/hear. Sounds great driving off. Thanks

Now it sound wayyyyy better

This is a very well thought out and edited video, good choice of background music which does not drown your voice. I wish that all videos would be that good. All my vehicles have Corsa exhausts, but I like the sound of yours! 👍

I am glad to hear it. Enjoy every minute.

Thanks for the tips and inspiration. I had been looking at a comparable Borla model for my tricked out 2013 Rubi and procrastinating. After seeing this, I got going and changed over to the Flowmaster featured in the video. Amazon had a good price with Prime and it arrived in 48 hours. Install took about 3 hours, all in all. The tough part was removal of the old exhaust. The WD40 tip for the rubber hangers was spot-on Thanks! I would also add to use a large pair of channelocks to easily pop off the lubricated hanger from the exhaust pipe without damage. Just set the jaw spacing so you can place one jaw on the outside center of the steel pin and the other on the inside rubber, against the side of the pin and gently squeeze. No need to buy the special tool. Similarly, loosen the existing exhaust clamps and then liberally spray WD40 or other penetrating lubricant into the slip joint of the exhaust pipes to loosen them up because they stick tight. After doing that, I was able to twist-rock the muffler loose relatively easily. Prior to lubrication, it wouldn’t budge. I used the same lube process for the front pipe and then “convinced” it loose with a hand sledge and a block of wood, tapping the resonator to drive the pipe off the collector pipe. Install of the new pipe couldn’t have been easier and only took about 30 minutes.

I'm a Magnaflow guy myself, but this sounds real nice.

First time for me on my jk 2011, started to upgrade on it. 2dr is my first time and started with a Gibson exhaust and it's amazing sounds. Very fast also the door handle and it's almost finished with an upgrade to it.

JK's should only be made with 6 speed manual transmissions. Totally awesome ride. I also agree that it's a Jeep, not a car.

Thank you for the informative video. I just yesterday purchased a 2016 rubicon and will defiantly be making the switch over after viewing this.

Great video! Very clear, awesome camera and editing work! We were waiting for our JKU’s stock exhaust to die first, but might be bumping up this upgrade to the top of our list after seeing your vid!

Went with your advice. American thunder is getting put on while I type this. Can't wait to hear and feel the difference!

Just literally finished installing this on my 2013 JKU, i ended up trimming 2 inches off the first pipe coming off the Y pipe. I counldnt get the tip on otherwise. I think it maybe because of my lift, 2.5 TF suspension lift. Anyway it fits perfect and sounds great. The hardest part was the factory clamp near the Y pipe and then disconnecting pipe from the Y. Removing from the hangers was not much fun either. Get yourself a bottle of WD40 or something for sure!!!

Greetings Jason... Just wanted to drop a quick note and provide some feedback on this video as I probably watched it 15+ times over the last 6 months. I really appreciate it! I received my kit just yesterday to install on my '08 JK. I know you made this look real easy and honestly it probably should have been, however that stock pipe on a 2008 JK was a pain in the butt to remove with rusted bolts and hangers that had never moved an inch. Also, to make it ever harder all original slip fits were tightened upside down (especially the first one) so I had to use a heck of a lot of PB blaster etc. to get that to loosen with no space to work etc. (The muffler for whatever reason what welded to the slip fit so I had to get the saw saw out to cut it apart. A quick note to older JKs, the first part of the new installation is a little off. The first hanger is for 07-11 JK and the second is for newer. (Not really 2 vs 4 door) Also, my stupid pipe had some sort of soldered round ring I had to cut of with a saw before anything slipped on there. Also, the stupid slip fits in my package were so tight that I had to completely open every one of them (everything going everywhere) then tighten them back together with tools to get them on the pipe. Yours were just rolling around around the pipes. Finally, the last part of the exhaust pretty much rests on the rear sway bar. There is absolutely no space whatsoever. I bought a set of the Synergy rear sway bar relocation brackets to fix it all. Thanks again for putting this one back up as I think the included instructions sucked and I couldn't have done this without you!

Nice sounds good I Just got done putting a flow master super 44 dual kit on my ram 1500 with the 4.7 got love that flow master sound

very excited about the jeep. Can't wait to see what's next.

This put a smile on my face . Love it

Congrats on the jeep. The manual transmission is awesome but I got rid of my stick shift because of the 405. Now I live farther out and the stick shift would be the way to go.

Sounds great. Great choice with the manual.

Watched the video again now going to pick one up for my 2015. Then the last thing I will need is a lift but thee way down the road thanks

I have the same year Wrangler, automatic and sport. I have bought it when it came out, and have put on some wide ass P265 tires.

Awesome vid! For anyone who wants great sound but can't afford it the factory resonator sounds a lot like a turbo muffler. Remove stock muffler big one in back and get a 2.5 inch id turn down and clamp it where the muffler clamped on

I just want to say great Videos. I enjoy the fact that you show a lot of great angles and very informative!

Excellent videos and approach that most of us can relate to i guess..From Bahrain, own a 2015 white Rubicon unlimited, planning on easy mods, Flowmaster was not at all on my list till i saw this video..Now minds made up, Thanks and more jeep video's pls..

just had this installed on my 2015 2-door Wrangler. MAN THIS THING IS LOUD! I don't know is it because the car was so quiet before and all you heard was the wind noise, but now it feels so loud I have to watch my throttle around the neighborhoods. I expected this to kinda be half way loud between the stock and current level. It sounds SWEET however, very rumbly, lots of pops and gurgles on engine braking mode. Sounds very good on a manual transmission JK. I was actually following a SRT grand cherokee and couldn't tell which car sounded better. It's a weird feeling driving the same Jeep but it sounds like a freaking race car

Flowmaster all the way. Good job, nice video. The Flowmaster on my 4.0l TJ sounds much more beefier than the 3.6 but great choice nonetheless.👍

I had seen some videos of the AmericanThunder Flowmaster system... but it did not sound as good as it does here! I was really looking for that FLOWMASTER 40 sound. I had a 4 cyl YJ with one of those, and man that sound'd almost like a V8. I am really reminiscing on THAT sound! Hopefully I'll achieve something similar to that in my JKUR!!! Thanks for the vid!!!

Sounds good and great ground clearance

I've got a flowmaster 40 series custom exhaust on my 16 JK and I'm happy with it. The exhaust has a nice tone not a hot rod but sporty. I did notice a slight loss of torque in the low range of the rpms which I'm not happy about but it does pull better in the higher ranges.

Your videos of Jeep Wrangler are great. Congratulations.

Very nice.. Sounds great. I have the 2015 Rubicon (black) which is identical looking to yours.That was a much earlier installation than I would have guessed.

it sounds great, thanks for sharing.

I'm kinda surprised by how quiet that JK was with the stock exhaust on it. I daily a Chrysler 200 with a 3.6l and even though the exhaust is 100% factory with a resinator and suitcase type muffler in similar locations (only centered since it's fwd), it has a slight snarl when started and driven. Good choice on the Flowmaster too, I really like how your JK sounds and have heard both generations of 200s running single, rear mounted Super 10's and love the sound.

Ordered today. Should sound sick with my long tube headers 😎

I was thinking magnaflow till i saw this! Damn you! Good video, but hey, its a Jeep not a car! lol

That sounds great!

I love it so much This is what I've been looking for!! Thanks my dude.

Thanks for the video! I just ordered this today for my 2011 JKU rubicon!

p.s.: Glad you joined the club... NOTHING BEATS A JEEP

yeess!! it's a jeep thing!!.... awesome JK sounds pretty good.. some 5:13's on 35's, nice winch bumper and good lightning and your set... such a capable vehicle the rubicon!... i had a TJ rubicon for a while, then a WJ but i just had to go back to a XJ ...but some day i'll get divorce or something and will be able to afford a JK rubicon jaja... great video as usual!... saludos from mexico!!1

Have myself a 2016 backcountry edition, with the stick shift!

Sounds great! I went with a Spintech muffler on my 4.0L and I absolutely love it! Of course I hallowed at my cat to help it breathe a little better. I'm honestly surprised how good yours sounds though, great video!

Mine was so much harder to install. I think its because my rock krawler lift moved that rear sway bar back an inch so i had to remove it and connect tail pipe and then bolt sway bar back to the frame. Its also a very tight fit and evena fter adjusting 12 times it still touches some of the parts of the underside of the jeep. The hangers dont line up perfectly even when the pieces are adjusted and double checked they are all the way into the slip fit connections. My Ace pro series steel rear bumper has the tip resting against it rattling so i may cut the tip or bend it a little or grind a notch in the bumper. The sound is great and worth it once installed. I think i forgot and threw out the hanger pieces that go on the end of the posts after install. I can probably order some but dont think they will come off as the exhaust is pretty tight in there.

"I'm going to keep this pretty practical." LOL!

props for being a man and getting a stick shift

Wow this things sounds great!

Keep these videos coming!

Stop calling it a car! It's a Jeep! I will be ordering that very same Flowmaster kit for my JKU. Thanks!

good job!! sounds amazing. nice tip with wd40 I usually go for the lithium in the spray can, have lots of wd around though.

I just bought 2 of these for my TL

Very nice! I'm also a Flowmaster fan. Have a 50 on my 5.7l XK now. Been looking to pick up another JK and will consider this. About as good as I think the 3.6l can sound.

Great video as always! Sounds awesome, might have to do something like that on my dads Jeep

Your videos are seriously Amazing love them keep it up. I just started alittle car channel myself I ran out of cars so I'm doing games for now

My 2011 JK Sport Wrangler is a manual 6 speed stick shift and I wouldn't have it any other way.

Nice! Awesome video! Stainless is the way to go!

What a good video.. makes you want to buy it

Sounds sick. and the install looked fairly simple!

Love the video and the installation I just wish the connection was the other way around 6:36 cuz to me it will make sense to have the bigger opening on the back so that way there's no resistance when the muffler is in use and maybe collect condensation

Sounds good. Like the new found clearance

Hi Jason. I really like this new project vehicle and I'm looking forward to new episodes to see what you'll do next. Take it easy Man. -Drew

Beautiful!! Great job man

I'm new to working on this car... I like this car.. 😲🙃😥

Glad to see you bought a 6 speed, sounds better than stock.

So this went on pretty easy. Just threw out the directions and followed your video. The only real trouble was the 15mm bolt for the clamp closest to the Y. Seems like jeep put it upside down.... Oh, and even with WD-40 those rubber hangers are a pain.

It is practical to those who own suv, 4x4, or pickup. My excuse is that, I am around 190cm tall... and I always been driving my 97 Cherokee but recently got my 2016 Wrangler Rubicon.

👌👍sounds awesome , have to get this exact for my 16 jku Rubi, NICE

LOL at 2 min in you say you're not putting 40s... I guess you are not lying with the 38s hahahaha

Stuck in my house so im watching your vids from the start! Question on the exhaust Jason, does it have drone? At any point?

I have always been leery about putting exhaust on a V6 because they sometimes get really tinny and raspy. I think that is a horrible sound. This 3.6L actually sounds pretty good. I have a 2016 Sahara Unlimited that I think I need to get a new exhaust for!!

4X4ever Jeep!!! DE VEHICULOS MILITARES A HISTORICOS AVENTUREROS YEAH jejeje

Great video! Thanks for sharing it.

Great video... I just purchased the same exhaust for my 2016 JKU... One question... Did you really need the ramps, or did you find the extra lift was more helpful in putting things together? Thanks for posting this along with the other vids... Very helpful and shows what to encounter when attempting. BTW, please don't refer to the Jeep as a car. ;) lol

this sounds great!

Love it man so functional

Sounds great!

Props for the 3.6 over the 3.8

It sounds really good!

Sounds awesome!!

i took my muffler off not only i saves green but sounds better than an upgrade

It would be better to see mechanical exhaust cutout installed BEFORE catalysts in order to get super cool loud straight exhaust. Other than that I cannot see any advantages against OEM. Maybe only that you change it on perfect stainless steal material.

"and I'll give her the beans"

I've watched all the videos up to the six pack shocks you put on this jeep. What would you estimate you have put into this jeep since you bought it ? If you can , give a break down of self installed price and estimated installed of everything you have done including the 37" tires. I like the build of this jeep and I'm considering a new 2017 Rubicon. The other thing that came to mind is , since you had beefed up tie rod ends and entire suspension and put up the Rubicon suspension for sale. Would you go back and buy a cheaper model jeep since you upgraded the already beefed up Rubicon suspension ??? I spoke to a complete jeep remodeling garage , and they advised buying a jeep wrangler or sport and building it up , as opposed to buying a Rubicon and then building it up since suspension is going to be changed. Thanks , hope you can shed some light on my concerns and choices.

Gresat video! Ive been looking for an exhuast for my 2013 JKU, Im sold!!

Actually for the two door you have to cut 22.5" off the pipe that goes after the muffler

Great video. I've been looking for a nice throaty exhaust system for my `15 JKU and glad I found your video. That's EXACTLY what I'm looking for. Time to go buy mine. The install looked really easy. How long did it take you and what, if any, was the biggest pain in the ass during the install? Also, I see you still have the stock bumper on your Jeep. I've been reading reviews where people are saying a metal bumper is recommended because the exhaust was melting their OEM bumper. Your experience and thoughts?

Only thing I don't like about this (and most other exhausts on the market) is that the tail pipe should fit OVER the muffler, not the muffler fit over the tail pipe.... Its a very easy fix for companies to do, but they chose to do it wrong in most cases. If the tail pipe is over the muffler, there is a less chance of an exhaust leak.
