Stillen headers its good and you'll get some gains from that like about 11.5 hp 18.5 lb/tq probably even more gains after a tune

Mike what other mods have you made to your exhaust system? Stillens headers will only give you that kinda torque if they're converter delete! Most of the restriction is the OE cats, replacing them with high flow cats (HFCs) is where you'll pick up 6 to 8 RWHP. By doing so you'll also find yourself running lean and throwing a error code which will require a Osiris tune to correct, which is where you'll gain another 25 WHP and a bunch of torque! Headers themselves will only give you 3 to 5 WHP gain at most which is why most of us consider them a waste of time and $$!

If you've done the intake/spacer and exhaust an Osiris tune should be your next step. Cost is in the $600 range, they put your G on the dyno and change the parameters. Should give you another 25 WHP and almost that much torque which will put a smile on your face for months to come.
