If you had a stock GSR with a K&N and had to choose one bolt on, what would it be and why? I'm considering The Comp Cams 57100 cams, an Edelbrock Performer X, header, or cat-back. What's the vote......

 

mine? Toda Header
second would be suspension
3rd.. rims of course.. but those have nothing to do with NA

 

Suspension first OR if you must bolt on go intake first but not for performance reasons. for sound!

 

Already have some Konig Feathers and the Tokico HP package. The Tokico blues aren't bad at the stock power level but they would quick become a nightmare if i took the power too much higher. Think motor mods, one vote for the intake, that performer x is a hot little piece from what i hear.

 

 

Ok trust me grab an intake so you know how your car sounds when it can breathe properly. exhaust should go after intake. but this is all my opinion

 

my header completely changed my motor.

 

header abd exhaust. vise versa..

 

traction bar or innovative motor mounts

 

i think a good header makes the most power on bolt ons but every motor is differnt
