wtf kind of exhaust is this

agreed that sharp bend in the back makes me shriek if that would have been smooth and straight it would have alot more power

In all reality though i doubt the bends would hinder performance buch but it to me looks like a bastardized scooter silencer.

I woouldnt let that detour me though it looks descent.
 
Stick with FMF, Toomey or something higher end. My guess would be its out of england or somewere like that
