My H pipe has individual resonators on it, and I'm presently installing 3" downpipes (4 bolt, stock turbos) and resonated 3"-to-2.5" test pipes (or midpipes) to my 2.5" cat-back exhaust. Is this redundant ? Are the resonators adding much restriction ? Shoud I have gone with the H pipe resonators only ? Will the cabin noise be reduced further ?
