Ok I have an 02 2500 HD with an LQ4. I have CAI, Pacesetter LTs and ORY-pipe to a single in and single out muffler. I know the truck came with a huge dual in dual out set up from the factory. So basically it had a true dual set up. Is my exhaust, the way it's flowing now, giving me the best perfomance or do I need to redo my exhaust back factory with the dual, H or X? I rather not redo and leave it alone but just need to know. I called TSP and they said it was ok since the ORY-pipe was 3in. What do you guys think?

 

youre fine with the single 3"
