Hey Jarrod....

What kind of pressure are you running in the front tires at the strip. By
going to the wider tread and lower profile you increased your rolling
resistance a bit. Try airing the fronts up to 40lb. to reduce resistance.

If you think the Flowmaster is hurting your low end try this trick. Pick
up a 3" to 2-1/2" reducer and cap the exhuast pipe with it. Buddy at work
knows a guy with a Dak that lost *all* his low end after a Flowmaster
(picked up a bit) and the cat removal (lost it again). Tapped a reducer
on end picked some power back up. Created just enough additional
backpressure.

Just my $0.02.
