persian54 wroteOh I'm pretty sure that you and James make more power than me, actually. You guys got custom dyno tune and stuff, right? I got ESS because they had an off-the-shelf tune for my Akrapovic. I like it for what it is.next track even let's do a drag race
I want to see just how much slower 440lbs makes me

Cured that damn torque dip from Akrapovic down low. Good nuff.

... lol, the old addage used to be every 100lbs makes you 1/10 of a second slower in the quarter mile. Don't know how true that is but yeah.
