so far I have bbk long tubes bbk off road h pipe, mangnaflows, and 3.73's. I'm getting a k&n cai, asp aluminum pulleys, steeda g-trac stage 1 for sure. Now I need suggestions on a few other mods. Has anyone heard anything about the bbk off road LT x pipe? I want to get it just because it would be easy to install. I was thinking about a dr.gas x pipe and having the exhaust shop make the rest. The only thing about that is I have to take the tags off my car and take it up there on a trailer. I'm also stuck between a edelbrock performer rpm, the rpm II, and the trickflow track heat mainfolds. Whats the difference between the rpm and rpm II and is either one better than the trick flow? I was also thinking ahead and looking at a aeromotive fuel pressure regulator, 190 iph fuel pump, mass air flow, and 65mm tb. Any suggestions on the maf and tb brands? Thanks for input!
