So right now with stock headers, very dirty air filter (cleaning that this weekend) and a catted H I'm putting down 280rwhp and 300Ft-lbs tq. How much more rwhp should I expect to see with LTs, VRS X pipe and a clean filter? I'm thinking around 30rwhp with my setup for a grand total of 310rwhp (370+crank hp) and 330 Ft-Lbs.
