How To Install a Motorcycle Exhaust at RevZilla.com 

***** 0.0 ITS YOU! LOL

Whoa, this comment just got pinned?? 😨

I thought I had an exhaust leak since my arrow pro race exhaust was so loud compared to the akrapovic. I ran it with just the headers. Yea def no leak lol its loud as shit with no muffler or mid pjpe

Destruction manual steps are universal: 1) Point front of bike to a hard and/or immovable object. 2) Apply liberal throttle. 3) Release clutch. 4) (And this is important) Bail out before point of no return. :-)

+WRXXXual Lmao XD

Undo some boys, yank the old and stuff the new, screw back those bolts Truly a beginner undertaking

Did that happen to you?

+the BOX1313 First off, congratulations! Now to answer your question. It depends on the bike, and it depends on the exhaust. If you're just installing a slip-on exhaust, you generally do not need a fuel controller. If you're installing a full exhaust (slip-on and headers), you'll very likely need a fuel controller. For many Akrapovic full exhausts, fuel mapping is not required, but you can still increase power and response with a fuel controller. I recommend reading Lemmy's great Moto 101 articles on exhausts and fuel management for more insight. -DrewZilla *www.revzilla.com/common-tread/motorcycle-exhaust-101 *www.revzilla.com/common-tread/fuel-management-101

It is always recommended to install fresh gaskets whenever possible. Such a low-cost piece will ensure your new system functions optimally. These gaskets can be sourced from any Yamaha dealer. -TeamZilla Chris

Generally you don't need to change the air-fuel ratio when installing just a slip-on. With a full system, you usually do. -DrewZilla

I mulled this over with Lemmy, and here's what he had to say: _"It's a bit hard to diagnose your install without being able to see it, and I don't think we even sell that product for your specific bike, so I can't get one off the shelf to look for you. I don't think there should be a gasket, but sometimes high-temp RTV silicone can help seal up an exhaust. Pipe-to-pipe fitment is fairly important here, and judgment is hard to supply over the internet. The clamp needs to be snug enough to seal, but not so tight that it damages a pipe. I've seen them use specs of 15Nm, which I think translates to about 11 lb.-ft., but that's a very general answer."_ Hope this helps! -DrewZilla

RevZilla Thanks for the quick response, you guys are great. I thought about something like the silicone already but didn't try that yet, it seems like the only option though since it's a very tight fit already. I'll let you know if it worked!

Generally speaking, yes. -DrewZilla

Thanks for reaching out, 5TRYD4! That's a good question and Lemmy has a good answer in the link below. -Hi-Viz Brian * www.revzilla.com/common-tread/installing-an-aftermarket-muffler "Popping and lean-running issues: Generally speaking, a slip-on can be installed without needing a tune. Note I said “generally.” Depending on your elevation, bike, other modifications, and a whole host of other stuff, like which muffler you chose, you may still find a need to change up the fueling. Heck, because of emissions regulations, most rock-stock bikes right out of the factory would benefit from a fuel controller or carb re-jet, anyway. Except for a slim minority of cases, most people can get away with an aftermarket muffler without altering the fuel system. If other parts of your bike undergo modification (like later you add some headers, or you have a high-flow air filter) plan on re-tuning the fuel system."

You probably should tune your carburetor. -DrewZilla

If it's a slip-on exhaust, there shouldn't be a major change. If it's a full exhaust, the bike would likely run leaner. You would be increasing the airflow without increasing the fueling. This can make the engine run hotter than recommended and potentially reduce engine life. Lemmy has written some really informative articles on the subject. -DrewZilla *www.revzilla.com/common-tread/motorcycle-exhaust-101 *www.revzilla.com/common-tread/motorcycle-exhaust-201 *www.revzilla.com/common-tread/fuel-management-101 *www.revzilla.com/common-tread/air-cleaners-201

Oh, they definitely vary from bike to bike. That's why most exhausts are bike-specific. -DrewZilla

No, if anything removing the baffle will give you a slight increase in performance. I ride a ktm 990 with akrapovic pipes, and the first thing I did was remove the baffles. I like it when inattentive car drivers can hear me coming!

Slip-on systems don't tend to bring the need to remap fuel, this might be just why

They're available at most auto parts stores. -DrewZilla

If only installing a slip-on muffler, the ECU generally does not need to be updated/changed. For a full exhaust (including new headers), you may need to change the ECU. -DrewZilla

+Spam Can No need to apologize, as others have already brought up the same point. However, I must mention that both pronunciations are acceptable. -DrewZilla

+RevZilla +RevZilla Yeah, I'm the idiot here. I googled it and found that out *after* I wrote my post. I never got around to deleting it, my bad.

We don't take a stance on it. You have to look at your bike warranty and manufacturer suggestions then make your own decision. -DrewZilla

You can if you want to, but it's not really necessary when just installing a slip-on. -DrewZilla

RevZilla That's what I'm hearing but wanted to be sure.. myths of fuel/air mix becoming too lean or burning valves had me questioning it. Thanks!

Yeah, it's low risk with just a slip-on. -DrewZilla

+airplaineman123 The short answer is "it's complicated". We aren't lawyers, but Lemmy goes into more detail in his Motorcycle Exhaust 201 article linked below. -DrewZilla *www.revzilla.com/common-tread/motorcycle-exhaust-201

You can install it whenever you want. If brand new, you still need to follow the bike's recommended break-in procedure. -DrewZilla

@@RevZilla thank you!

You're welcome! -DrewZilla

I have a super tenere. Thinking maybe a two brothers.

***** Thanx Lemmy. You're the best.

There are some exhausts that are C.A.R.B. approved for use in California. I recommend contacting one of our Gear Geeks to help you find the right options for your bike. 877-792-9455 or cs@revzilla.com. -DrewZilla

No, slip-ons are bike-specific. You can use our _Shop Your Ride_ feature on our site to see the specific exhausts available for your bike under our _Exact Fit_ tab. -DrewZilla *www.revzilla.com/motorcycle-exhaust-pipes

Without looking at the bike and the parts, it's hard to provide a solution. I recommend consulting a factory service manual for a correct diagram of all the necessary parts/gaskets and their placement. -DrewZilla

I didn’t know Europe was a country

That's a pretty specific muffler and heat shield, so unless you're willing to do your own fabrication, you'd probably want to stick with the stock muffler. -DrewZilla

The stock exhaust is about 10.5 pounds, while the Remus is about 7 pounds, so that's a 3.5 pound difference. Akrapovic makes a slip-on that's even lighter at 6.6 pounds. -DrewZilla *www.revzilla.com/motorcycle/remus-hexacone-slip-on-exhaust-bmw-f650gs-f700gs-f800gs *www.revzilla.com/motorcycle/akrapovic-slip-on-exhaust-bmw-f650gs-f700gs-f800gs-adventure

Most exhausts available for the 650 and 1000 are slip-on exhausts, so you keep the stock header pipes. For slip-ons, you do not need to remap your engine, nor do you need to do anything with the O2 sensor. -DrewZilla

RevZilla absolute legend!! cheers mate!

Christopher Williams hi, what sort of sealant can I use for that ? I have just installed a slip on but I think it is not 100 ,% after riding it for some miles.

Try removing the slip-on and reattaching, so that you can attempt to get a better seal. -DrewZilla

Thank you, I will try that

+iamgeeoh It's always good to have gaskets on hand in case you need them. Some exhausts include them. -DrewZilla

It depends on the bike. What bike and exhaust do you have? -DrewZilla

Geekchess Cheers! -HVB

No, I apologize, but we do not have a specific tutorial/manual for installing an exhaust on a TMAX 500. However, it should be very similar to this video. -DrewZilla

ARTJUNKIES No, it's not really much different, except that the mounting locations are slightly different due to the shorter overall length. Due to the short overall length, most exhausts for the FZ/MT-07 are sold as "full systems", which include both a new exhaust canister and new headers. -DrewZilla

Thanks! I' getting an FZ-07 at the start of 2016 and the stock is kinda quiet (which in my mind could be dangerous) and I wanted to know for sure if you can change it out. RevZilla

If you just install a slip-on, you likely do not need to change the map. If you install a full exhaust (including new headers), then yes, you need to change the map. -DrewZilla

Those things have teeth sometimes, ***** :P

I'm only familiar with ceramic coatings on exhausts, as it helps dissipate heat. I cannot speak to ceramic coatings on paint. -DrewZilla

RevZilla oh okay thank you sir

On

For a slip-on, no, you generally do not need to tune. For a full exhaust, yes, you generally do need a tune. -DrewZilla

Sometimes it can take some muscle to get everything to fit, but also be sure to follow the instructions for the order in which to tighten everything up. Otherwise, the pipes will be out of place. Also, it's a bit hard to diagnose an issue over RU-vid, so apologies is we can't provide as much help as we'd like. -DrewZilla

@@RevZilla I manage to fix it. After measuring we found out that it was a 0,9mm difference so I kept it straight and my friend pushed like a gorilla and then we could get them together. Rest was walk in the park. Thanks for answer and keep up these awesome videos!

You're welcome!

Generally not with a slip-on exhaust. If installing a full system exhaust (slip-on AND headers), then generally you would want to rejet carbs (if you have carbs) or retune the fuel injection with an electronic fuel tuner. -DrewZilla

First step is to try to identify where the exhaust leak is. Then disassemble and reinstall, making sure all pipe connections are seated properly and properly tightened. If that doesn't resolve the issue, then you might need to reinstall using a bit of exhaust sealant for the leaking connection. -DrewZilla

+Samrat Singh If it's freer-flowing, the engine will likely run leaner, that is to say there will be more air per given amount of fuel. This makes the engine run hotter and can damage the engine in the long term. If your engine is carbureted, you would need to increase the fueling to make it run richer. If it's fuel-injected, you would need to somehow alter the ECU. -DrewZilla

THANK U SIR FOR UR VALUABLE ADVICE ,,, MY BIKE IS A CARBURETED ONE (RE CLASSIC 350) SO IF RE JET THE CARBURATOR , THEN DAMAGE IN ENGINE CAN BE PREVENTED OR NOT ,,,OR IT WILL DAMAGE THE ENGINE THEN ALSO ???

SIR WHAT IS RE JETTING ,IS IT THE SAME TO INCREASE THE FUEL, WHICH U HAVE WRITTEN ???

+Samrat Singh "Jetting" or "re-jetting" means to optimize the air/fuel-ratio by adjusting or installing different carburetor jets. In your case, I recommend finding a knowledgeable Enfield mechanic to help you tune your engine. -DrewZilla

Try a penetrant, wait, then try a rubber mallet to loosen things up. -DrewZilla

+Kawaii Ninja That's standard as any residue inside the exhaust burns off. It should go away after awhile. -DrewZilla

+RevZilla thanks

+mini bikelife Generally, motorcycle exhausts are bike-specific. -DrewZilla

okay thanks

Freeski Swizzy Pretty sure we do! :D -DrewZilla *www.revzilla.com/motorcycle/remus-hexacone-exhaust-system-ktm-690-enduro-smc

RevZilla ahhh, didnt find it for some reason. thanks

Doesn't seem to be any dents or excessive scratching for this to be happening, I saw some bikes with traces of rubberised substance arround the seal. Would that sort it? And what is it?

That would be exhaust sealer, and it might solve the issue for you. -DrewZilla

We consider slip-ons and mufflers to be the same thing. Exhausts are sold as slip-ons (mufflers) or full system exhausts (including the headers). Can you clarify your question? -DrewZilla

+RevZilla I mean what is better to install, slip-on exhaust or install full system exhaust? And if I will install one of them do I have to change something else in my bike, like air filter or something else? (I got ninja 250sl and I want to install akrapovic titanium exhaust) Thanks!

If you get a slip-on, you won't need to change your fueling, but if you get a full system exhaust, it's likely you will need to change your fueling. Whether you get a slip-on or a full exhaust, you aren't required to change your air filter. You can increase airflow if you change your air filter, but you'll need to change your fueling (with an ECU re-flash or fuel controller) to take advantage of the increased airflow. If you want to change the stock exhaust without having to change anything else, just get the Akrapovic Titanium slip-on. If you want to spend a lot of money to add only a bit of power to a small bike, then get a full exhaust, air filter, and fuel controller. -DrewZilla

+RevZilla thanks! you help me a lot!
