I bought the header package from SLP, P/N 30214. I already had the SLP LM II. SLP documents 28 HP gain at the rear wheels, with no tune. My butt dyno agrees it put some power to the pavement. I haven't had my radio on since I installed them, SLP got it right on the sound ommiting from the tuned exhaust, truely high performance music to my ears.
