i dont know what i want... There is probably quite a sound difference. I dont think ive ever heard dumps. Are they too loud in the car?? Ive heard the mac 2.5 catback with 3" tipsand i like it. I dont mind alittle drone but i dont want it so bad i cant see straigh while driving. I want a muscle sound.

 

the dumps will be a bit louder in the car and I imagine the drone will be ungodly. I'd go with 2.5" CB as their isn't a need for 3" pipes with your mods.

 

i think hes talking about a 2.5 inch catback just with 3inch dumps..

it is louder in the car, but it sounds so sick
