Great Style and Fit

The exhaust was extremely easy to install and emits a deep throaty sound. I would not recommend the DB killer quiet insert. The quiet insert works! But too well for me. From the deep, clean noise that this exhaust makes, the quiet insert makes a HUGE decrease in the sound. This means its more of a quiet swoosh than a grumble. I immediately took the quiet insert out after one long ride and I’m in love with the sound of the bare exhaust.

Awesome power increase and sound!

After my crash on my 2016 R6 I had my mechanic install my M4 GP on it. The increase was very noticeable and it’s makes my bike a whole new beast!

Loud and sounds amazing, super clean!

Put my exhaust on today and it was fairly simple and it sounds great and clean only problem is that you will need to buy a $60 Servo Buddy eliminator if you have the 2017 Honda CBR 1000RR

Aesthetically pleasing!

I purchased the M4 GP slip on for my 2018 GSXS-1000 in hopes of improving the sound of the bike. The sound did not increase. However, the M4 GP slip on looks phenomenal!

Great look and PERFECT sound 18 GSXR600

My wife bought this slip on because I didnt want to get crazy with air/fuel adjustments of a full exhaust system, had to get a power commander and have to dyno the bike. It brings out the GROWL at low rpms and idle but it isnt loud with the cat and baffle in. It's a perfect tone in my opinion. I would've rated 5 stars but my slip on wouldnt seat all the way to the factory cat. I removed the ring seal for the stock exhaust as the instructions said but I still couldnt get it to seat against the CAT. I clamped the h*ll out of the clamp provided and used the spring tensioner and it doesnt leak, I would have just preferred it seated against the stock CAT to make it truly look that it belongs.

Looks clean

Super easy to install. Looks very clean with factory heat shield. Good sound, but not overly loud since it keeps the factory resonator.

Great M4 GP Style exhaust for a great price

Installed on 2017 CBR 1000RR. Easy installation, great fit and it sounds awesome. Also added some power on the top end. It sounds moto gp like on the go pro. Make sure you get the servo buddy as this upgrade eliminates the need for the exhaust servo. Do not hook the battery back up until the servo eliminator is connected. Install takes less than 2 hours start to finish.

I will just say this! Since I installed this slip on It feels like I just bought new bike! It sounds GREAT and I feel more power that bike produces! Only regret is that I didn’t do it sooner! But, be aware! It is loud and on longer rides you might want consider earplugs! It is true GP!

Q: Did a Cat delete on my 2008 GSXR600 so I was wondering if I would have to buy a mid pipe since then pictures show the slip on connected to the Cat.

A: Most of the time, it's not absolutely necessary to tune your bike after installing a slip on. Manufacturers, however, unanimously advise to tune the bike for optimum performance. Basically, there's a good chance you won't need to tune it but for the bike to run exactly as intended it will need a tune.
Q: I have a 2009 Zx6r with an M4 already attached. Can i just take that one off and slide the new one on?

A: This particular exhaust doesn't fit a 2019 ZX6R. You want part # KA6922-GP19 and it does eliminate the stock exhaust valve and muffler box, but retains stock catalytic converter. So it may cause the FI light to turn on.
Q: Will this fit a 2005 zx10r

A: I am sorry, but it will not fit on your bike. They start fitting on the 08 models.
Q: Can I use - different headerwith the M4 exhaust instead of my stock header?

A: That would depend on which header brand you wanted to run. You would need to gather the technical measurements (inner and outer diameter) of the connector pipe, then call M4 to see if they would be compatible with the muffler the make for your bike.
Q: Does this exhaust come with the adapter to connect to the header or the cat?
