Coffman's Kawasaki Ninja ZX-4RR / ZX-4R (2023-2025) Slip-On Exhaust

This slip on exhaust blew all my expectations out of the water!! It sounds sooo good, when you really get on it and use the quick shifter of the 4RR it sounds sooo good I can’t help but giggle!! 1000/10 would recommend. Honestly just wow!

Video doesn’t do it justice. It’s sounds amazing and looks great. Definitely louder in Person.

Good quality exhaust. It is not too loud. It has a beautiful note and makes the overall look of the bike very clean. Good purchase.

Easy install, fits like a glove, no exhaust leak, sounds amazing. Support your USA/local business. For the cost of this exhaust, it is more than money well spent. Stop buying those China knockoffs!! Get yourself Coffmans exhaust, im glad I did!!

Had questions....quickly answered by owners. Placed my order, item shipped priority, coast to coast in 2-days. Installed in 5-minutes and changed my riding experience immensely. What a sound!

I'll add that I listened to A LOT OF YT videos for the sound I liked best. Cost wasn't a concern. I bought the classic for my ZX4RR because I thought it sounded best (and secondly, because it looks so clean and minimal). Those videos were not wrong (to me...it's subjective, I know)!
