It's amazing how much faster the spool up is. I can actually manage to break traction while already doing a slow roll (yes, I think it rocks even if it isn't very special). I'm surprised my exhuast isn't very loud either.
I put on my SS brake lines yesterday and decided to gut the main cats as well. I figured out why my brakes sucked so bad. I had all kinds of air in my lines. At least it's all fixed. Now I can stop on a dime.
