Hardparker, how hard was the DP install? You retain the O2 bung(s) on the UR Catted model correct?
Also I do NOT like loud. I have a turboed SR20 with a straight through 3 inch exhaust no cat and hate it. It's loud and drones on the highway. With the stock exhaust and the UR Catted DP how loud over stock is it?
