I have notices since I got my aftermarket exhaust system. A pypes mid muffler duel system and two new magna flow catalytic converters. My sound in the exhaust and the aggressive tone is gone. It now wont get very loud and sounds like a terrible rumble. I have also notices a whining and wheezing sound on acceleration and a decreasing acceleration rate. Its like it doesn't want to accelerate like it used to.
