Just curious.
Yeah, I notice a BIG difference. I get a tremendous ammount of power (over stock, with the muffler on). I only take off the axel-back portion... I am NOT running off of my header... I run off of the 2.25 pipping after the race cat. I have tried running off of just the headder once, and it did nothing but make my car EXTREMELY loud... no power gain whatsoever.
