Proper expansion chamber that runs across the bottom

[Dylan57]

I’ve heard about the Sick Bike Parts expansion chamber, but couldn’t find the one that runs across the bottom. I want a proper expansion chamber, that will give me a performance boost atleast close to an MZ65, but doesn’t run across the top of the bike. I would also prefer one without a silencer, just the expansion chamber. The Banana ones would work perfect, if they were real expansion chambers, so if anyone knows of anyone knows of anything that fits that, please let me know. It would be going on a CDH YD-100.

You're not going to find a ready made expansion chamber type exhaust with a long enough divergent cone to have any good performance.

Most have to be custom built.

i mean if your down for the challenge I don’t think it would be to hard to bend a cdh 67 lower on a bike
