Neelnug,
I removed my resonator about 2 weeks ago. When exhaust is cold, it can get real raspy at about 2500 rpm I think? and later on thought e rev range. as the car warms up, the rasp gets tamer. Still a little fart canny for my tase though. I Think, and I stress think I have picked up some MPG and a little power which I notice on the Highway. Not dyno proven, just what I THINK. Hopefully, somebody else will say something about this mod. You might want to give the search a shot, sometimes I can actualy find something worth reading there
Later,
Chris S.
