what exhaust diameter ???

i was wondering guys! what diameter would be suitable for a boosted tc 2.5" or 3". is there any benefit of running a 2.5" downpipe with a 3" exhaust?

if you can afford it, 3 inch exhaust. assuming your talking about turbocharging. if your supercharged, all you need is 2.5 inch.

open downpipe is the cheapest route though lol, more power and less weight but you will smell like crap lol

yeah ptuning exhaust kinda sound like a plane, combined with a turbo without an intake pipe that sounds like a jet engine

I hear my turbo spool loudest then my dumptube then the ptuning exhaust
