Excellent Service and Speedy Instal

Definitely buying more from Bill in the future. Excited to hear what the 636 sounds like in the AM. Also for anyone looking into getting this Mid Pipe, it definitely fits an LV LV10 slip on!

Incredible sound

Sounds amazing. Installation is effortless. I like that it comes with a db killer for racetracks with noise regulation.

M4 Exhaust All Black Full System MT-09/SXR900 2021 - 2023 YA6932

24 Z900 M4 Headers

Purchased from Bills and everything went great, Bill emailed me and a bunch of others to give us an update about when M4 would most likely ship out products and it was spot on. The exhaust fits great had a little trouble pairing it with an SC CRT Exhaust but that was a matching game and was nobodies fault. Overall great experience will do business again whenever I need more parts!

Excellent product

I needed to upgrade my stock fender and didn’t want to cut wires and this product was easy to install and you use the factory license plate light without cutting wires. The installation was very easy to me. The customer service is great and also the shipping was very fast which I was impressed and definitely ordering all my parts from Bills Exhaust.

Vandemon 4-2-4 system for z900rs

Great system. Unfortunately there are no instructions whatsoever. I assumed that a clip went between the left passenger foot bracket and ended up breaking a $100 foot bracket on my motorcycle. Couldn’t believe it!!! How hard would have it been to just put a simple drawing in with the exhaust system to at least picture how it needed to be assembled. Hopefully JB Weld will glue this back together. :-(
On a brighter note, BILL’S EXHAUST STORE is absolutely awesome!!! Super customer service and Bill was really nice and kept me updated on my order the entire time. Highly recommend!!! Thank you Bill !
