Review on 🏍️ M4 14-17 Yamaha FZ-09 Standard Slip-On Exhaust: Enhance Performance with Carbon Fiber Construction by Patrick Hamilton

This m4 exhaust sounds and looks great! The packaging was very good as it was double boxed and fully bubble wrapped. Installation was easy but took a long time as I used a hacksaw to cut the pipe. It's definitely faster with a cutting disc. The exhaust fits perfectly. Everything installed, started and checked for leaks. I found there was a little leaking where the clamp attaches to the head tube. I used a large amount of high temp silicone as the instructions say. So I removed the complete exhaust system again and just welded it on.
