03gtmustang said:Ahhh another header thread. Most popular headers are probably bbk, hooker, and mac. As for gains, this 01 bullitt got 20rwhp and 15rwtq with bbk headers and a bbk h pipe. Another guy on here gained 23rwhp with hooker LT's and a hooker o/r x pipe. Definitely a worth while mod, which Im planning to do this summer. Ill be getting the mac lt's with o/r h pipe.
The loss of backpressure will cause you to run rich. Thats why you get a tune!03gtmustang said:Someone correct me if Im wrong, but dont headers make your a/f ratio a little richer?

If you are running lean you want a tune ASAP! Lean is very bad!!! Lean means there is more air than fuel and that is how you blow the motor.03gtmustang said:Thanks, just wanted to make sure. Im running lean right now so maybe I wont need a tune?
Yeah...don't get it tuned until after the longtubes. I wouldnt suggest many WOT runs though!03gtmustang said:Yeah, I know Ill have my lt's in a couple weeks so Im going to wait for a tune.
For $75 I would do it. It would be nice to have a before and after. If you do that post them up on here for sure.03gtmustang said:I can get 3 pulls for $75, so maybe Ill get a before and after dyno with the lt's so I can see how much I gained and where my a/f ratio is at before and after the lt's. Then Ill get a tune if needed.
