for stunt? Anything goes... YOu dont really need to much power to do stunts... its al labout balance...

but its also not bad if you have few extra HP


and avoid high performance exhusts...

Bu what exhaust do you prefer ?
I'm searching for a low boy exhaust what is very good for stunt. Do you think the Yasuni R2 is good ?
