11-16 SUZUKI GSXR600 & 750: M4 GP Series Slip-On Exhaust - Black (BLACK)

Easy to instal and sounds great!

This exhaust of fricken amazing. I thought my bike sounded good before. But come to find out, all i was hearing was the engine and the intake. This slip on really gives the bike that sporty sound that you love to hear. Absolute music to the ears. At low rpms it gives the bike a deeper growly resonating note. At mid to high rpms the bike just screams! Havent taken out the baffle yet (as i dont see the need to). I live in an upperscale apartment complex and dont feel like really pissing off the neighbors. All in all i feel like this is the best looking slip on available for the gsxr. I cant say its the best sounding because i have no frame of reference. But so far (other than my frame sliders) this is the best purchase I've made for my bike.

Pefect Pipi for this Bike! Looked for days before buying this M4 GP 15 min install metric allen wrench metric socket wrench is all u need . Just remove lead muffler gasket , rubber groumet 4 heat shield from old pipe Use groumet on new pipe for heat shield dont use lead gasket off old pipe Muffler fits Perfect This is the Pipe u want Sounds way healthier than stock Louder in a good way Sounds like racer now instead of stock pipe Sewing machine Left baffle in still sounds Perfect Talked to a ASE Mechanic No Remap on air / fuel needed unless u remove the cat box.... Also remove passenger pegs buy a rear seat cowl in the bike looks Sick!!!!!

Nice add on to my bike. Gave it a deeper tone.

M4 GP exhaust for 2014 GSXR 600. Thanks to Amazon Prime, got the item in 2 days. The stock exhaust on the bike was pretty light compared to my previous bike, but this M4 is even lighter. Definitely smaller in size and fits nice and clean. Installation: I was done with the install within 15mins. Very easy to install. I'm not a professional mechanic by any means and the tools I used was a wrench and Allen wrench, not even a socket wrench. Came with necessary parts for the install. After removing the stocker, there is a metal gasket you will have to pry off, either with a flat head screwdriver or a knife as it gets caked on the hot pipe, but it's also very easy to take off. Once installing, it does get a bit trickier as you have to twist and turn the small M4. The good thing is that this exhaust utilizes the stock heat shield. It also came with a pair of "M4" decals which I slapped on the heat shield as the shield conceals the exhaust pretty well...might have to get a conceal and carry license for this snug little exhaust..*badum tiss* Sound: I will try to make a clip with the baffle on and off. The exhaust does come with the baffle inside. To remove you need a needle nose plyer. Update: for some reason the baffle was not easy to take out. Tried needle nose pliers and ended up scratching the inside of the exhaust. After researching online, i purchased a ChannelLock 927 Retaining ring plier to take the baffle out. It was still very hard to take out and after some more scratchs got it out. They should have just used a little screw to place the baffle inside instead of the retaining ring. Now i gotta paint the inside as it's an eye sore now.

Looks great! I had to cut about a 1/2" off my midpipe with a sawzall to get muffler on all the way. I tried the included goop, and grease I had. There is no way that muffler was going on all the way without cutting the midpipe shorter. Sound is loud as you'd expect with a muffler that short and raspy when you rev it up, and that's with the baffle in. I could still hear the intake noise that the GSXR is known for however, especially with my helmet on which seems to block out some of exhaust noise.

This slip on looks really good on my bike and makes it sound much louder than the stock exhaust. Fairly simple to install and great quality product.

Gets rid of the bulky stock exhaust. Nice throaty sound. Only loud at higher RPMs so you can still be good to your neighbors. =] Any performance improvement would be psychological. Did not dyno test. Great deal compared to other pricy exhausts.
