I bet there is no actual power difference. Too bad you didn't do a before and after dyno to back it up.

 

Alex, did you have a dyno done before? Not that it really matters - just curious. It gives a great difference in the sound. That low rumble is MUCH more prevelent after the change. Not sure on the power difference but it is also approximately a 20+ lbs weight drop if I remember correctly.

 

Actually, we've done a before, when I dyno'd at 235.4. We will find out this weekend what it puts out post exhaust
