OP has VR, 160 thermo, Corsa Sports and a Cartek Tune. Results: 367 RWHP and 370 TQ. By way of comparison, I have Callaway CAI, 160 thermo, Kooks Headers and Hi flow Cats with X Pipe and a Cartek Tune. Results: 384.5 RWHP and 373.7 TQ. For purposes of this discussion, assume all parts were bought NIB. OP spent appx $400.00 less than I did and got 17 HPR less. Granted, he has Catback, I do not. Maybe he got some ponies in there, maybe not. Headers are worth the money, especially when you start making lots more HPR. Just remember, your engine is nothing but an air pump: if it can breathe through a big mouth on the inhale, don't expect it to fart through a pin hole on the exhale and still make lots of power.
Remember, ask Dave and Julio at Cartek - they will tell you that the stock exhaust cans can handle upwards of 500 rwhp before the exhaust becomes a hpr limiting factor. They will not say the same for the exhaust components that come before the mufflers.
