I need clarification.
1. Do the turbo-back exhaust systems include the downpipe piece coming straight off the turbo? (You'd be surprised how dense I am):dunno:
2. Does a 4" MBRP turbo-back straight pipe installer series have a true 4" downpipe or a 3.5"?
3. Do the 5" MBRP turbo-back straight pipes have a 4" downpipe?
Thanks for shedding light!
