M4 Exhaust All Black Full System MT-09/XSR900 2021 - 2025 2026 YA6932

Mixed Feelings

The shipping process was a disaster. Upon checkout the site said "2 weeks" delivery time. However 6 weeks later I get the exhausts. However, one of the exhausts was incorrect. Somewhere along the way, my order got mixed up with another person's order. So I had to reschedule my install and tune while they shipped me the correct exhaust. Throughout this process I am disappointed with Bill's Exhausts customer service. Probably won't order from them again. That being said, when I finally got them, the exhausts look and work great.

Looks great sounds even better !

Awesome packaging! Looks just like what I wanted! I'm installing it this weekend and will write another review. Edit: Got the exhaust installed! First time doing a full system myself (well with help from a friend lol) so it took a while! But man was it worth it!! Sounds great, nice deep rumble! Can't wait to get the ecu flashed and experience it in full form!! Great buy! 10/10!!
