I think I might just buy the header and make the rest myself. I was going to buy the cat-back first and add the header later, but now I am not sure. I don't really like the huge tip, but its what I could find. I may just put on the header, skip a cat, and exit right before the left rear tire. My main concern right now is keeping exhaust out of my cab, and hopefully increasing power. These trucks are so underpowered. I might just be my truck though, because I don't know the history of this engine, and I blew the original engine. The first truck I drove for any length of time was a '91 F-150 with a mildly built 302. When I switched over to a Toyota, it kind of made me laugh. It works pretty well until I try to get over 65 mph on the highway. I am afraid to take the engine much over 3000 rpm, especially after blowing my last engine. What rpm can I take these engines to? Also, what size exhaust tubing should I use? I thought 2.25 in. because that's what LCE is using, and they have probably been doing exhaust for these engines longer than I have been alive. But I also know I need a certain amount of backpressure for the exhaust to scavenge correctly. Now I have no idea what I should do. Suggestions? Thanks!
