best mods per $$ IMO

Stillen Gen 3 intake
Hotchkis Sways
ARK dual exhaust
HFCs
UPREV Tune

I have the ARK dual + Stillen Headers & HFCs and it can be raspy depending on what gear and rpm range you stomp the gas on. IDK if its caused by the headers or the HFCs. Wish there was something i could do to eliminate it. Any ideas i would love to hear. . .

Intake, hfc, cbe, and uprev is all you really need, IMO.

Weight reduction is another great cost effective way to make your G faster.

You literally saw a 20hp gain to the wheels from just HFCs? Sounds hard to believe

I don't think the HFC's gave much of a power boost. Not enough to feel, anyway. I have Berk's on my car and you get a better sound, no engine lights either.

How about swapping out the stock headers, would that make a difference with HFC, CatBack system and a tune? Or is there no need to change the headers?

Lol! I know, I was doing some research.

I'm referring to Swapping out the stock headers on the car, replacing with an aftermarket.
