Wuts Straight piping do ?

Make ur Exhaust super loud!

yups tru dat...but ups 2 u

Like noticeably loud that it will attract cops ?

yes much louder. your problem is that i don't think you could do it with the tC without having the pipe hanging lower than normal. there is a path in the underbody that the pipe follows (and it ain't straight). so it looks like it might have to hang lower than the underbody which means first speedbump = crunch.

i thought straight piping also included the notion that there was no restrictions in the pipe (like a cat or resonator)...is this also correct?

yes hollowed out or no cat at all

also read as no back pressure
