Re: needswings dual cold air intake or magnaflow backcat exhaust???
Exhaust is for your pleasure, little HP gain. CAI on an N/A... same thing. Sprint booster will get rid of the throttle lag, no HP gain. A tune however, would help the car. It's your $$$$, but that is the facts.
On the supercharged cars, all those things, but exhaust, helps. As we need more air for more boost.
