i dynoed my 03 yesterday and i hit 398 hp and 393 tq with just a c&l mas kit and diablo sport Predator tune and 2 clicks to left on the fuel base is this good numbers for these mods or not?
Still running the stock exhaust? If so, then YUP! Good numbers! U.M. P.S. Now go get you a CB and watch those number go to 420 or more!!!!
Definately nice numbers. My car pulled 396.2/415 with a bassani x-pipe w/cats. Everything else was stock from the cat-back to the paper filter. I just got my predator tune and it feels more powerful. I'll dyno again when I get a catback and intake done.
No dyno with the stock H-pipe, but there was a shop to compare 3 different cars and they show no HP/TQ improvment by swapping out only the H-pipes for aftermarket. The cat-back system is more of a bottleneck than the midpipe is.
so your saying the stock h-pipe is worth keeping on the car and the aftermarket mid pipes are a waste money on a lightly moded car? its gotta be good for at least 10-15 hp. what about cuting of the 2nd cat on the stock h-pipe?
