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 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.
