Kooks LTs, Kooks Y w/ high flow cats, 18" bullet muffler in the I pipe, over the axle splits off and 2 (1 each side) 12" bullet mufflers with dumps. NO RASP, ZERO, ZILCH! U gotta go with something like this if u don't want any rasp but still high flow.

I think if you added a moroso spiral flow then it will cut back that rasp. I wouldnt put cats on it. Way too expensive and you will loose more performance then if you just added a bullet.

i have the same thing...... i am straight exhaust out the back XS headers and Y to a nonmuffled borla...... lets just say it is deafening to anyone outside the car.....
its resonance from the exhaust being only 1 pipe.... and i agree the only way your going to get rid of it is cats ....
do you get this resonance at 2200-2500 rpm at steady throttle and it disappears???? if so its exactly what i have. heres what im getting
