Lets start with dp. First off is ive read write ups on doing these and all of them said dropping the transmission is a must. Is this true? Do able but would rather not. Second is three inches optimal for these TT's? Or would 2.5 dp's to tail pipe be sufficient? I dont plan on building the motor any time soon (internals). Than test pipes. First do they throw a CEL? Ive been looking at z1 2.5" test pipes. Any good? Any info or opinions is greatly appreciated!
