We packed tons of horsepower into these pipes, 20 to be exact! The top end speed is increased immensely as the Thunder Cat tops out at almost 190 hp at 8400-8600 rpm which is a proven 130 mph.

We do recommend ‘V-Force’ reeds, jetting, clutching as well as a crankcase modification (that can be done here at Jaws).

We offer both a triple glass pack silencer system or a 3 into 1 trail muffler.

Definitely the pipes to have on your Thunder Cat!  

Also available to fit into the ZR chassis.


Crank case modification $500 (only top half of case is needed)
