exhaust mod, trx 3.3 sleeve fangs
guys and gals, im looking in to some mods into my trx 3.3 engine and exhaust, the first modification
ive done research on was drilling out the stinger on the exhaust. i have a chrome SC pipe which i have just drilled out today. boy i tell ya , there is a definite change in power and responsiveness. the sound too! (make sure to richen the HSN)
another mod im looking into is making fang like incisions on the piston sleeve as seen on the RBmods website
has anyone done this , if so i need some guidance regarding what kind of cutting tool i require and how to perform the cuts.
here is the pic of the pipe,
