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 $$!
