Ok I have a friend that said he would sell me some Mac LongTube headers and a Custom off-road H-pipe for real cheap (around 100 bucks) anyway I was thinkin on gettin those with 2 flowmaster race mufflers and turndowns before the rearend... what kinda power gains do you think I'd see? my exhuast now is stock manifolds stock H-pipe with 2 cat's and Dyanmax Bullit mufflers.

Your not gonna have enough backpressure therefor wont get as much out of it as you could with some different mufflers, go with 2 or 3 chamber and youll see better numbers.........

if its a 99+, i've seen gains as high as 30hp to the wheels from headers, o/r midpipe, and catback, and a k&n. My buddy has a dyno shop. Lot of 4.6 99+ with the same results.

What you should do after you get them is Save for an X-PIPE somthing like a drgas would be my choice.
