Fantastic service and exhaust

I was looking for a 2025 z900 exhaust for my bike. I purchase a first one with Cycle gear and after delivery I noticed that it was the wrong one. I find bill website by my own research he took his time to call me and explain me what I need to buy on the exhaust after the purchase the shipment arrived really quick. That guy is amazing I highly recommend check him out if you need parts and exhaust for your bike. Great service and assistance and quick to respond

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.

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!
