This what I run on my Evo Powerpipe (pic on details). I like the look of the straight back exhaust.

I would not recommend running this without the pipe, since the exhaust will shoot straight down on to the scooter.

Stalker™ exhaust for the 43/49cc midbike/superbikes. Features a baffled interior design for a lower noise output, while still offering exceptional performance.

Includes billet canister, spacer, gaskets, and 6x65mm mounting hardware.

I had to slightly open up the holes in my powerpipe to get it on. You will also need two 10MM locknuts.

I used the manifold that comes with the stalker, but the clearance is pretty tight to the tire. You may want to leave the manifold off, and shorten the bolts. Fits: *Notes: May also fit other applications - slotted center to center mounting spread is 1.59 - 1.7". Exhaust opening is .6 x 1.08".
