M4 Exhaust manufactures exhausts which add power and a more race-inspired sound to your bike as well as lowering the overall weight. Extra time on research and development ensures your exhaust has the ultimate in quality workmanship, ease of installation, and the best performance possible for your motorcycle. M4 Exhausts are available in both Standard / Race and GP Series mounting configurations.

  • The GP Series mounts much lower and forward than stock, right near the right rider foot peg.
  • This mount will give you that "GP" look and sound.
  • Enjoy a deep, throaty tone from the lower RPM range through the mid-range - open it up and it screams MotoGP!
  • The M4 GP Series Slip-On Exhaust has a built-in baffle, tuning the exhaust note for a crisp head turning sound.
  • M4 has built a quality fitting exhaust that is a breeze to install; all mounting hardware and instructions included.
  • The GP exhaust system will shed some weight over stock to give your sport bike improved power-to-weight ratio.
  • M4 slip-ons are designed for use with the stock header assembly.
  • Satin M4 aluminum name plate.

Note: All M4 systems are designed and intended for closed-course competition use ONLY.

Looks good on my GSXR. Sounds amazing as well. Had to warm up the engine in order to slip on the M4 exhaust. With the bike being cold the exhaust would not slide in all the way. Shipping was excellent and shipped right away. Overall I would buy again and recommend this

Perfect fit on a 2015 Suzuki GSXR 600!

-For most sport riders, you know the first thing majority bought is an aftermarket exhaust and in my opinion, this shorty is worth the money!
-Customer service is outstanding as they answered my shipping questions and got it here on time. (quick shipping!)
-A big difference from the stock exhaust when opened up at mid-range to full open. You really get to hear the potential of the motor.
-Easy to install, it took about 15 minutes from taking off the stock exhaust to completed install of the M4.
-It also uses the stock exhaust cover so you don't have to go buy one. (a plus!)
With one of the lower priced slip-on exhaust for late model sport bikes, this is definitely an option when considering swapping out your stock exhaust and I highly recommend this product!

Big difference from stock exhaust!

Better than I ever expected

First off, great customer service from Motorsport. I happen to live only a couple hours from the main warehouse but next day shipping is still amazing. Install for this was pretty simple. The hardest part was getting the prechamber off. I ended up using a rubber mallet to lightly tap on the top of it until it came out. Other than that everything went easy and quick for exhaust removal. Install was easy. Be careful not to scratch the swingarm putting the upper nut on the bracket. I put down some tape. I left the servo under the seat and just removed the cables. That way no servo eliminator is needed. As for the look and sound, no video does this exhaust justice. It is loud, but it is amazing. Especially when you get down on the throttle, this exhaust gives you that amazing go sound. The quality of the unit is very solid. Great build quality and it looks very easy to repack when the time comes. I was torn when what exhaust to get but I think I made the right choice. Amazing product. I would recommend it and this site.

M4 GP Series Slip-On Exhaust

This pipe is a very balanced set up.SUPER easy to install and sounds pretty sweet...A lot of people say it's to loud,NO WAY. I was actually thinking it could be louder,no B.S. Pipe sounds really good when your getting on the throttle and super quit when cruising on the freeway..Great deal for 200 bucks,and my GSXR -750 LOOKS KILLER WITHOUT THE PASSENGER PEGS !!!
I ALSO ADDED A YOU TUBE VID SO YOU CAN HEAR PIPE..PIPE SOUNDS BETTER LIVE !!!!!
PEACE OUT !!!!

Satisfied purchase

I bought this M4 and installed on my 08 gsxr 600. Even with the cat still on it sounded very good. Since, I deleted the cat and now the bike performs better, and sounds like a beast. I am more than pleased with my purchase.

Great slip on for the price.

i put this m4 GP on my 2011 GSXR 600 just to get rid of the big stock pipe. this exhaust is not much louder when idling but like others have said, when you are riding this pipe will scream and it is a nice sound that turns heads not the annoying sound. it looks very clean and well fit on the bike. installation was easy took about 5min. and motorsport always has my orders at my door within two days which is amazing. faster than any dealer around me.

M4 or Two bros?
I've been trying to choose either one but it's a tough decision! Which one is louder? Personally, I think I like the sound of M4 more but a mechanic was telling me that Two bros comes with a better quality but M4 sounds the best on ninja! Is it technically proven? Tnx

Is tuning required?
Is engine tuning required after installation on a 2009 Suzuki SFV650 Gladius?

Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

It is not absolutely necessary to re-jet or re-map after installing a new M4 system. Your bike will run fine if you don't. In most cases, however, the ride and performance will be enhanced with optimal jetting and mapping.

How much will the package weigh for shipping?
Was wondering how much this weighs and the dimensions of the packaging it is shipped in. So as I can determine whether I get it shipped from you or sent to my US address and shipped on from there. Cheers
