Ok...i have a stock 99gt auto with 47k on it with just a catback system but i'm lookin to moddify it...it seems like everyone says gears but i'm afraid it will run such high rpms because right now it runs around 2100...any suggestions

just do gears. i run 3:73 gears in mine and drive it on the highway all the time. no issues.

yea 3.73s are a great gear.good performance gain and not bad at all on the highway.i picked up mpg around town and maybe lost 1.5 on the highway well worth the performance improvement

gears will give you the kick but as for bolt ons they all give about the same power part to part. all bolt ons will add up. best bang for buck is of course vitamin N20! all up to you and what you want.
