MPH and Times with Full Exhuast

[302N20]

Ok I need some help from you guys since I'm not a termi expert. What does a full exhuast, full weight, stock pully, stock wheels, coupe termi, trap and run in the 1/4?

I'm sure many of your guys know this off the tops of your heads.

Thanks

I went 12.20@116mph with a cat-back only.
