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

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…
