I was going to use rob's log headers but the cost and unproven efforts of any headers kept me from going with them. I have a magnaflow TRU internal X-pipe muffler to go where the rear cats are and a magnaflow "Y" to bring it asll to 3" piping. Then I planned to do a resonator delete and finish with a Borla Pro xs 3" in and out. The Borla does nor drone. I would think having 2 muffler would keep the car quiet or i would add a round perforated muffler where it would fit. I want it quiet. Would I see a couple of tenths from this or would it be a waste? Thanks, mark
I realize this is just about a duplicate, please ignore one of the threads, sorry and thanks, Mark

 

Everything I read says it's a waste. I am waiting for Rob at Needswings to prove this to be wrong with dyno results. Until then, my exhaust will stay stock.
