damn thats a bit rediculous. A bit overkill maybe. shep ran a mid 8 with a “full” 3.5 exhaust… Now he changed it up but what kind of power do you plan on making?

I think its perfect, 4" is all around better alot less heat and back pressure are you going to go all the way back 4"?

looks awsome V band downpipes are SO nice
