899 panigale slip on

Arrow Ducati Panigale 899 14-15 /1199/199s-R Homologa Ted Titanium Rh+Lh Works Silencers With Carbon End Cap For Original Collectors 71836pk

Top notch customer service!

I recently needed a complete exhaust system for my 2024 ZX 4Rr, and after contacting several companies for price quotes, I found Bill's Exhaust. Bill was extremely knowledgeable and helpful in guiding my decision. I received the best price and my order arrived quickly. I highly recommend Bill's Exhaust; he's earned a loyal customer.

M4 exhaust pipe slip on

I love the pipe I will purchase another one when I purchase my next bike thank you so much for the kinds and courteous service that was provided to me and for me Bill is awesome

Allen Littles

M4 Exhaust GP Black Slip on GSXR600/750 2011-2025 SU6112-GP

Lighter, Great sound

Very easy to install. Wonderful sound! Only issue is it could use some kind of sleeve or gasket at the header/ silencer connection. On my ‘23 Tiger 900, the connection was fairly loose, with the clamp at its limit to get tight.
A smaller diameter clamp might be a remedy too. Otherwise, a perfect fit.
The db killer seems to be mostly permanent, requiring some concerted effort to remove ( YouTube) It does come with a screw to secure it, should you be inclined to remove it.

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!

M4 Exhaust All Black Full System MT-09/SXR900 2021 - 2024 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!
