Very nice!

Installed on my 09 r6 with a gytr slip on, sounds amazing. Did my ecu flash at the same time, really woke up my bike, great and cheap modification vs a full exhaust.. I would recommend the m4 mid pipe to everyone!

Worth every dollar !!!

Pretty simple install if your handy with cutting tools. As for the sound to put it as simply as possible. The first week I had it a duck flew across my path from 30 feet away and slammed roght into my helmet. I stayed on the bike and the mallard got his first ride on a sport bike. Just press place order you won't be disappointed I can assure you

Outstanding product

Gave me the exact sound I wanted, I paired this piece with an akrapovic megaphone, although it is extremely loud and no video does this setup am justice, it is exactly what I wanted, fitment and install is great, just what I wanted

Great Purchase

For the price you can't beat it. It sounds great ( loud as heck with the gp slipon ) gives my r6 a nice deep rumble that turns heads everywhere I go.

Best upgrade for sound system!

The first experience purchasing with the company is great. The shipping was fast in receiving the cat delete y-pipe pipe. The installing was little long but worth it for the remarkable sound that comes out of it. I will recommend this product to other buyers for loud sound to there bike.

It was a little tricky to get on just right considering I did not take off whole exhaust system(headers). Took about 4 hours and lots of careful grinding and went on finally. Very loud. I took a 1 inch wood hole
drill and drilled out my cats as well. You will need a power commander.

Love it

Easiest and most afforadable way to make a full exhaust. Sounds even better with the stock slip on. Great product. I had mine Tig welded and definitely recommend doing it that way. Thanks!

Q: What will happen if I install the m4 muffler eliminator kit but do not tune my bike with a power comander or something similar?

A: It most likely will not run correctly. For maximum performance a fuel programmer is recommended.
BrileyR6
Over 3 years ago
A: Once I installed it I felt a small amount of hesitation between shifts, and it will backfire alot when you let off the gas. You eventually will need a fuel management system or the ECU will need to be flashed to accommodate the free slowing exhaust.

Q: Custom dyno tune or download tune from pc5
Over 4 years ago
I have a 2012 r6 with k&n race filter, smog block off plates, pc5,m4 go slip on, m4 cat delete pipe. I was wondering if it would be best to have a custom map built on the dyno for me or go with one from power commanders website. Any help would be much appreciated.

A: You should be able to find a good map from Power Commander. If that doesn't work, I would then go the dyno route.
Dave
Over 4 years ago
A: Unless you have easy access to dyno services, I would go for the auto-tune setup for PC5 (I actually did this).

Q: Do I need to take off the whole exhaust off to cut off the muffler box out or can I leave it on the bike and cut it ?

Dexter
Over 4 years ago
A: You have to take it off. you might get away with cutting it off while still on but to sand it down and clamp/weld it together it defintiely needs to be off. its easier than you probably think though!

Over 4 years ago
A: Yes you gonna have to take the whole system out to cut the cat off cause you will have to grind off the ends of the headers smooth to get the m4 eliminator to fit right in.
kkr6
Over 4 years ago
A: You can leave exhaust on bike and cut it off. That's what I did. It just took a total of about 3 hours. (Grinding,cutting,and fitting just right). So yes. You can leave it on. Just be careful and watch oil pan
MotoSportGrantK
MotoSport Staff

A: Yes, you will need to remove your exhaust system before cutting as recommended by M4.
Dave
Over 4 years ago
A: You will want to remove it for sure, there is grinding you will need to do on top of the pipe, that would be too hard to get to when mounted.

A: There is a hole on the top of this Eliminator Pipe that would allow the OEM O2 Sensor to hook up to the pipe. I would recommend taking a look at the installation instructions for this Kit before purchasing.

A: This would come with all necessary hardware (including clamps) for installation. Note: Installation of the Muffler Box Eliminator Kit requires cutting the stock system at the muffler box. This is a simple procedure that is done with common tools. However, before ordering, we strongly suggest you read the complete instructions.
