I still haven't decided SLP vs. Magnaflow.....anyone know what size the SLP pipes are? The tips are 3.5" but I can't find anywhere that says the cat-back size. I had flowmaster series 40/2 chambers on my 01 cobra and they sounded great, i got the same ones for my 04 and they sound whimpier than the stock 01 exhaust. I want it to sound like a Nascar again! Anyone have any recommendations?
