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!

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

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!
