This exhaust has a race-tuned expansion chamber to help your engine make maximum power in the range of 4000-12000 RPM. The included variator parts are necessary modifications to help your engine rev that high and take advantage of the power available to it. Your stock variator setup doesn't want your engine screaming like that, so you've got to switch it up to make higher revs.

This kit consists of:

NCY Performance Exhaust (Bracket, ex gasket,  included)

NCY Super Transmission kit

You can always add a big bore kit later on!

Follow good break-in procedures, and work with an experienced tuner for best results.
