yea the resonator basically muffles the sound so when you cut it off and put a tip with just a straight pipe on it then it definitely changes the sound. It sounds lower and throatier...it is just right. lol when some good weather comes that's on the to-do list.
Where in LA are you?
The weather can't be any better then it has been the last few days. I'm a night washer also. I'm about to go clean mine right now.
Are you getting rid of the MIT and getting a full CAI?
