The dollar/horsepower ratio is really bad for short headers. OEM is rather well-designed. There's a reason most firms don't build aftermarket short headers - there's no demand. You could buy long-tube headers from Fast Intentions. The "long" part of the tube replaces your HFCs. But those will still add negligible gains and cost 18% of a twin-turbo kit. If you're serious about gains you're better off saving the money and going F.I.
