exhaust question

[AsianInvasian425]

alright i am planning out my stunt bike for this summer and i have a couple of questions

since i am going to be doing alot of parking lot stuff and know that i am going to drop it numerous times i am worried about the exhaust being able to hold up. i dont want to run it without a muffler either

i was thinking of custom fabbing a 06-07 gsxr slip on but havent decided on anything yet

also does anyone know where i can find info on piping sizes for stock bikes?

just cut the pipe you have down a little bit

Yeah just do a shorty mod exhaust.
