Shaun E from Trenton, NJ said, "Went very well once you get old system off, I had to cut it out. The only thing is you buy a really nice exhaust system & you have to use your old bolts to attach. Which for me snapped off when I took the old one off so I had to go out anyway & get new bolts. Very pleased w/ it, performance is better but I still have OE manifold & cats so I'll really see wut happens w/ my new OTTP header and only one high flow cat."
