Okay I am looking to get my exhasut system going. As most of you know I took my Manifolds off and my single exhaust was all rusted. I keep seeing y pipe and h pipe and dont know which one is the best or why they even matter. I am looking for the complete kit, and I know I have to get my headers seperate, but I am only finding 4v headers and no 2v.I am still dont know if it would hurt to get 4v or if it even matters. Looking for some ideas on what to get. I know I am trying to get the whole system for a good price, I can change out the mufflers if they are cheap, and I think a good 2 and a half pipes would be good. I am haveing a hard time finding a system that works, and the y or H isn't helping me. Is is bad if I have a 2v goignt o hurt me if I start throwing on all this 4v stuff. I know my valves are smaller and dont want to let it breath to much where it hurts because that is all it wants to do is breath and not suck, if that makes sense. If any of my topics aren't making sense I am sorry but I ripped off my finger and the army doped me up.
