I cut my factory exhaust off at the flex pipe and put some 3 inch pipes with out the cats going out the back with 2 single chamber flowmasters mounted in where the old resonator was. I haven't heard any of the production exhaust systems that are out there to base it off of but I think it sounds decent. Its definitely louder and I will put my headers on and dyno it soon.
I did notice it seems to be running a little rich afterwards has anyone else had this problem when cutting off the cats?
