Love this Shorty Coffman on my Ninja 300

By FW with a Kawasaki Ninja 300

I have had this on my 2014 ninja 300 for a couple of months. I love the sound of this thing and could not imagine having the baffle out. It is loud!!!!
I can say I have not noticed a power gain or power loss. I have not done any kind of tuning on the bike since I put the Coffman on.
It looks great on the bike and sounds awesome. If you were thinking about putting one of these on your bike, stop thinking and do it, you will love it… Loud pipes save lives….

It sounds like HUNDREDS of LIONS making love to a VOLCANO in a THUNDER & KILLER BEE APOCALYPSE!!!

Its not even the same bike anymore. Sounds soooo much better than the stock exhaust. Had to buy a drill bit and a pop rivet gun to install it but it was well worth it. The bike is a little snappier now as well because of how heavy the old exhaust was. HIGHLY RECOMMEND!

Just do it!

If you are like me you are scrolling through all these exhausts and thinking why are they so expensive? Then you come to the Coffman one and go well that's reasonable but it probably doesn't sound that good. Well you are wrong. I took the gamble and you should too! Those YouTube videos don't give this slip on any justice. It sounds amazing!!! I was more than impressed! Only thing if you want to secure this properly you will need to drill one small hole. They provide the pin. Other than that it take literally 2 minutes to install.

Looks awesome installed, makes the bike sound mean, and noticeable power increase!

My favorite exhaust!

I've had many well known brand exhausts, and now after a month of riding this exhaust i can honestly say I'm never going back to the others. The sound, is just perfect in my opinion. Pretty damn loud too, even louder without the silencer.

It sounds amazing!

I got it for my 2013 CBR250R and it maybe put a total of 10 minutes to install. Compared to the stock exhaust it is life changing. The stock exhaust sounds like a moped and this shorty exhaust makes it sound like it has a bigger engine than it actually does and it growls. Some reviews said that it was too loud but I would disagree, it is the perfect volume and gets everybody's attention! Overall it was easily worth the money and would definitely buy it again for another bike!

Very nice system! It makes my cbr250r sound so much better! It also made the ride smoother. Also, coffman is a great company. My old mechanic put the pipe on incorrectly (he didn't put a safety pin in) and the slip
