Okay I put a header on my car and removed the cat all on sat. Well my car is very quiet now. And their is a little rasp in the exhaust note. I am still using the oem resonator and I installed a 3.5" resonator where the cat used to be. So why is it qiueter. And i thought the resonator took out the rasp. Yes it sounds like a bee. So does the header make the car quieter? Is it possible that the resonator made it quieter than a cloged cat? Does to big a resonator cause rasp instead of removing it?

with greddy header, gutted cat, stock mid-pipe, and tsudo axle back,, my car was louder than fuck w/no raspiness in the exhaust note. when i got a custom mid-pipe w/o a resonator put on, it got really raspy but not any louder.
