05 G35c-Exhaust-Headers-Cold Air Intake???
 

Hi,

I have had my G for about six months and I have not made any mods to the engine. I do not want to add a turbo kit or supercharger(As of now), I was thinking of maybe a full exhaust with headers and a cold air intake. I am trying to get from 298 HP to about 330HP. What type of gains should I expect from these mods? Do you recomend any specific brands- Injen,Aem,Stillen,Greddy,Hks???

Thank You Kenny...
