Installing an "ULTRA QUIET" Resonator on the Straight Piped Z3 

Cool man; I think that resonator 'quiets' that down just enough, I think there's a fine line between loud & too 'drownie' & I think you've nailed it!

Finally a person who mounts rims with high profile tires! Besides the tire appreciation, sounds really good with the resonator.

Definitely loving the Z3. Your exhaust builds are really really clean. Lotta talent. Sound quality is very nice and gives the car a more aggressive quality. Keep it up. 👌🏻👌🏻

This is the best video by far. I've been looking for a video that demonstrates before and after sound effects with this ultra quiet vibrant resonator. I myself had my eye on this type of resonator to install on my 4th generation maxima. And I have been doing my research on the type of sound that am particularly looking for. This video helped out in determining the final application for my maxima. Thanks again

Really fantastic work. I've been looking for an example to show an exhaust shop what I want them to build for me, and you've nailed it. Thanks!

Sounds so much better, awesome work!

Yeah you are right. The resonator was needed and sounds great. I just picked up my project Z3 and it needs a lot of interior love and a little body work. The motor and 5 speed seems good so far. Drove it 20 miles home with zero issues.

I like the sound of the straight pipe but...the new setup seems more chill lol. Nice work btw 👍🏼

Big difference & still sounds nice! Real good job & nice shop💯👍🏿

Love it, love the way it sounded straight piped but resonated sounds good too. Makes me miss my Miata lol

I like the change! Definitely a lot easier on the ears of bystanders in the high RPM range. Sounds good overall, too!

Put one of these on my straight piped genesis coupe 2.0 and it made it sound so much better.

Good work! Think I made my decision for my E34 535i. I had the vibrant performance resonator on it and it was just too loud and raspy. This seems like the perfect balance, appreciate the comparison video.

Love the videos as always. I'd love to see you do a budget single turbo on the 135 like you did on the mustang

My old Toyota xrunner was running dual in line vibrant ultra quiets with a custom turbo kit. It sound exactly like this. Has a nice pur during regular driving but when you get on it it’s not ear piercing. Good choice on the resonator

Love the videos, car sounds great

Im gonna have to get one of these

I just got a m roadster I’m so happy and excited and it’s my first manual car I love it already I can’t wait to put some money and miles into this

Dude you made that look so easy. Haha. Sounds way better now

Nice, that sounds really good! I'm thinking of getting 2 of these for my 350z. I fabbed up a quieter exhaust, but it still seems slightly too loud. So these should do the trick

I have a 2000 2.8i Z3 with the standard BMW exhaust set up. I have to say that I think the standard set up sounds great and I wouldn't want to change it. Each to his own I guess.

Nice touch!

I’m doing my exhaust right now and this is giving me false confidence you makin it look too easy

New 2022 Mach1 HP owner here. Im thinking about my Active Exhaust options to comply with racetracks that have noise restrictions. One of the options Im considering is replacing the stock resonator with two Vibrant Ultra Quiet resonator bottles. Other option is keeping stock resonator and trying to fit regular Vibrant resonators behind it. Last option is an H-pipe combined with ultraquiet vibrants. Although I love the stock sound, I want to avoid getting kicked out of HPDE events when I use the Mach1 at W.O.T. Ive read that some M1 HP owners just pulled the AE fuse while the engine is running in AE quiet or normal mode, before pitting out on the track. Any suggestions?

Looks good! I know you live in PA so be careful I had a car failed for inspection for welding a hanger to a muffler. I was told it was "Modified"

I like only vibrant performance muffler street to install on mid pipe to make quieter with stock resonator and performance muffler.

Sounds way better!

Sounds cleaner. Still louder than I expected though.

I think the biggest offender and pretty common for whatever reason on BMW engines is rasp, there can be a few causes, and this did a good job curing that as well, its noticeable in before and after on the light revs during warm start to my ear. Loud engine noises are nice but when it just sounds like metal rattling around not so much, this is way better, more actual engine sound just enough volume reduction. Pretty good win win. Additionally i like duel pipes aesthetically but from single exit, or on most inline engines often don't like the way they alter sound, this one turned out good though, you still have some meat to the sound rather then it being too smoothed out. Must be just within margin of error i bet if you would of had even 1/8 inch larger on each the duel pipes wouldn't have sounded as nice.

Just ordered 2 of the bottle nose to quiet my flowmaster super 10s down it's no different than a straight pipe just too loud hopefully it works

im looking into getting a bmw z3 2.5i as my first manual here soon. The one im looking at has a muffler delete and Im curious would you say go with the resonator straight pipe or add a muffler back on? idk if it sounds louder in person compared to on video or not

Resonated is always king, apparently my Fiesta ST is loud but being resonated it's comfortable inside (even on the motorway).

It sounds great but Does it drone? Do you think two would be worth it? I've been contemplating using these to replace the mufflers on my s2k. I cut the mufflers off another stock exhaust.I really liked the raw sound of just the resonator with the muffler delete but it's too loud and don't want a boomie droning aftermarket exhaust like skunk or tomi.

Amazing 🤝

What would you recommend for 2018 jaguar F type 4 cylinder 2.0 exhaust system upgrade

hows the incab drone when driving at highway speeds? Got a car recently that was straight piped to the headers and it's ungodly loud, as well as insane drone even with windows up... Wondering if this will help it out lol

Damn. Just watched the last video. Wanted to straight pipe it. Now watched this and now realise I need more money for a res

Meet Kordare The Welding Robot, great work. Resonated sounds much better.

Did it also lower the interior noise or just drone? Did a muffler delete on a catless v8 and it sounds glorious but the drone and volume is just a tad too loud. Would love to bring it down 15% and reduce drone by a lot lol

It looks kind of small muffler which does its job quite effectively

Think i like it straight piped, but that's cause i really like noise, great job welding👍🏽

You know Vibrant have sense of humor when they brand that the Ultra Quiet.

The resonator sounds nice. Great work on the fab.

how was the drone change over all? I have a 2016 Focus ST with a 3" SRS cat-back (off a cat-less dp and big turbo), and its nearly straight piped...its SO droney its unbearable. I was going to add this ultra quiet resonator, hoping it cured the drone. The exhaust sound and burbles/crackles is nice, but the drone is so bad i wont even drive it with the family anymore, resulting in taking my SUV on weekends until i fix the headache inducing drone cruising around 70-80mph lol...

Do you sell this set up ? The only diff for me is my cat is gone so I would need from the y pipe and the spot for the second o2

Is the inside quieter? I have some drone sounds and vibrations I’d like to stop.

How is the packing on the resonator holding up? Mine burned out after not too long... it's now loud AF!

🔥🔥🔥🔥

But isn't that essentially a Muffler by adding that to a straight pipe? Just like to know before attempting mine. THANKS

Sounds great but still pretty loud. I know what would quiet it down more... 🐌

What engine does that powerful machine have, I have one just like it and I want it to sound that great.

Sounds nice resonated, gets rid of the fartiness 👌

Sounds so much better with the resonator, well done! Was lookin at doing this for my 4Runner. Thank you! 🛻 💥

Resonators are meant to go as close to the headers as possible; they're not supposed to replace mufflers.

Good evening. I tried to go to Facebook to contact you to ask question. I have 97 2.8 Z3. I need an engine or a rebuild kit. I have been trying to find a rebuild kit but cannot. I already have a cylinder head and gasket set for the top end. I need the bottom end, i.e. Pistons, rings, rods, bearings. Can you please advise where I can find such items as a kit. I really eant to get the Z back up and running. It is worth it to me. Thank you in advance. Jason.

I hate to say it but I think a big ol' spoiler would look great on this build

Do the resonator cut down the deep sound inside the car?

Any chance you'd sell the kit for the car if so how much looks so good 👍

Did it help at all with the droning?

You can tell the difference but I think somthing more substantial would be needed to get it down a good amount

I may go with this on a w210 m112, full delete, muffler, and factory resonator. Where is the ideal placement? Towards the end or in the middle

Does the resonator take off the drone inside?

i know you said you're an engineer but how did you learn how to do all this stuff?

Whats the part number for the resonator

It actually sounds like this resonator added drone. Did it do so?

What are the Dimensions of the exhaust

Did it get rid of any drone?

Sounds more refined

Bro. How much you spend for the whole exhaust?

does resonator affect the performance?

straight pipes always sound awful. Glad you put the resonator.

The resonator made it sound deeper.

I made a straight through custom muffler for my car and it is as quiet as a stock muffler

I’m trying to get rid of a raspy sound on my car.

this is a m52?

It can never be too loud.

It's not straight piped if it has any interruptions in the exhaust

It’s not straight pipe if u still have stock cats on like cmon now guys

You cant call it straight pipe if it has cat in it. Cat makes it more quiet than resonators.

Better before

…I hope that wide body fender bit isn’t finished because that looks like some poorly plastic molded flake peeling toy.

Question Sir?? Di your car passed inspection with just the resonator?

What was the drone like before and after?

SMH!!! People for the love of the gods stop saying it's a straight pipe if there's cat or a resonator, Omfg 🙄😒😏😒
