... i took my cats off and im running a magnaflow oval case muffler and stock manifolds and my **** pops and is raspy and i was disappointed when i heard it I did the same thing. Using a 4x9x11 Magnaflow, removed teh cats and replaced with straight pipe, exiting in front of the pass. rear tire. The rasp was killing me. Especially on the interstate. I bought a 3" x long bullet muffler and put in front of the Magnaflow, and ran my exit like bigkids
and it sounds great. Its still loud outside, but sounds great inside.

Another thing that will definately affect your 'rasp' of the exhaust is if your running a straight through non-chambered muffler. When I ran with no cats & a dynomax bullet it was loud but did have some rasp at certain RPM's. Now running the same non cat'd exhaust and a center in-center out 3" Aerochamber gives me a sweet and decently loud sound but with zero rasp and zero resonance.
