I bought this muffler because it was so much less expensive than the stock muffler plus its a little lighter, and less bulk, and sounds just a good as the the OEM. muffler.
I got the M4GP about a month ago and was installed on my 2017 gsx r600 in literally 10 minutes at idle it’s has a really good deep sound to it and while riding it screams
I'm very happy with the look and sound of the M4 gp Slip-on. Best bang for the buck. The only issue was installing it. It has a slightly smaller diameter than the stock pipe which made it an extremely tight fit. It took everything I had to get it all of the way on. Turned a 10 min job into an hour. Almost gave up. Use the grease it comes with! Over all, happy with it. Just be prepared to give it all trying to twist it on.
Sound is superb! Installing was a breeze! Finish was awesome! Looks great!
Bought this to replace a Yoshimura slip-on I had for a few years, and I made a good choice! I have it on a 2012 Suzuki GSXR600, I do feel the bike is a little snappier on the gas, but overall hp gains is probably nonexistent; but this was bought for its sound, not for performance, so who cares! The only negative comes from my bike after the install, since the pipe is short, I now have this circle piece with a hole on my passenger peg where a longer pipe would screw into, it’s a little ugly, but oh well, not the M4 pipe’s fault.
