Review on Upgrade Your KAWASAKI Ninja 400 with ISTUNT Motorcycle Slip on Half Exhaust System Muffler Pipe: Full Glossy Black 2018-2021 by Donotello Figueroa

I'm really surprised at the quality and finish of this canister! I bought this for my wife's 2018 Z400, it looks and sounds amazing. It came with DB killer installed. I bought an M4 exhaust canister for my sv650 a few months ago, paid $450 for it and that canister is well made too and even prettier, seriously it's a steal, top notch fit and finish. They even provided a spring puller! Three things, first, the screw didn't fit, wasn't long enough, so I used the standard screw. Secondly, the springs are not of good quality, they deformed in the middle when installed, I used other springs that were better. Third, I wish they hadn't used artificial carbon fiber for the canister ring, just a steel band would raise the canister's valve even higher.
