What next?
 

I was wondering what I could add next on my '04 GT... I have intake on it and super 40's mufflers and thats pretty much it. I have underdrive pulleys waiting, I need to find someone with an impact gun so i can take off the alt pulley first.... After that i am not sure what to do next that will not void my warrenty just yet....

I wouldn't take the time to put pullies on a car, but alot of people like em'.....anyway, do you have a good midpipe? Headers? Gear? Tune? Any of those would help it out. :)

I'd say either gears or LT's. Those 2 will yield the biggest gains. Otherwise, just save your money for some sort f power adder

LT's??? and I had already bought the pulleys so I might as well put them in :). I should have those in by the end of the week. And as for gears, I am buying 3.73's. But I do not know when exactly yet. Other than that.... you say chip or something.

LT's....Long Tube. As in Headers. Chip and tune is pretty nice, start out with something like that.

oooooo okay... headers, yea I should. And chips :)

Def. headers and a midpipe.

what are some good LT's and midpipes?

SLP LT and Midpipe, Just installed and I am ver happy with them
