Exhausts for GP100

[MarlinHemi]

Hiya I was wondering what if there are any exhausts with an expansion chamber that will go straight on my gp100 or do i have to get one custom made,

cheers

Third pic is the RG/RM spec pipe, fourth pic shows where we cut the flange end off and turned it down in the lathe to fit the GP cylinder. Cutting it here made it easy to re-align the pipe to fit onto the GP.

Found that an old Honda RS125 pipe is close to what I need for my new engine and has the right tuned length and other features for making max power at 9,500 rpm on my GP.

Maybe not straight on, but easily modified to fit. Follow the links back to the original posts for the details.
