no low end

well i finally made it to the track and was upset to run a 15.2 at 93 mph with a 2.6 60 ft. Of the line it seems as if I bogged until the r'shiznit about 3k then she pulled like she was supposed to. Is my stall too low for my engine upgrades. i have the b&m 2000. or is it due to a lack of backpressure due to me removing the all the cats and running true duals of each header never meeting. I think the exhaust is 2.25

Dude, That 60 foot is dismal...... with a good launch I can't see why you wouldn't run a mid 14 second pass.  What was your launch technique?

Your exhaust is fine for your setup by the way.

hmmm.....
Do you have a trak-lok in the rear and is it working properly?
What kind of tires/rims did you run?
What was your pressure?
How much gas was in the car?
How much stuff was in the trunk?
What kind of shape are your shocks in?

If you are using street tires, you likely spun causing the bogish feeling(and the 2.6 60ft). On the race track the rubber on the line can fool you into thingking its not spinning. The mph is enough for a mid 14 with a good launch..

If it didn't spin, then you may have too much fuel pressure making the low end soggy.
