just had a magnaflow race series muffler installed 500 miles ago. i know that you have to let them burn in a bit, but i was expecting a bit more sound. it sounds exactly like the stock muffler. is that huge cylinder under the car towards the front a resonator or is it a secondary 3 way cat? if so, i didn't see any o2 sensors running into it. has anyone removed this monstrosity? any info? tia

Sounds like that might be the problem. I was thinking about the magnaflowand this guys sounds good, but he also had headers made.
