Lost. I read everywhere that X pipe is good and produces less back-pressure. Now comes my Question. Please respond if you can. On a let's say 4.8is, If I remove CAT converters(in my countrey, they don't care) + Install an X-pipe. I think i'ts going to be better. What do you say Jordo? I assume It would need 2.25 Dual without longer pipes(Just X-pipe) right? Thanks alot, Sorry to bother.

Your not going to get any performance gain. Little better throttle response and more even louder sound. I have my cats and removed the resonator put in x-pipe and Dinan mufflers. I would go with different cheaper mufflers if I did it again.
