214/218 from tsp i just put in mine really woke the truck up. I needs a converter. But the truck does fly with it. chirps the 1-2 on 20s

 

Do I need the converters? Im in KY and there is no emisions check. I have a 04 5.3 auto reg cab. Volant CIA, Corsa Cat back, Custom tune on the way. Im getting ready to do a Comp 218/220 cam swap, 4.10s, and long tube headers. I was wondering if there was any advantage to getting rid of them? I figured since the shop was going to have to do some exhaust work to use them with the Corsa I might get rid of them.

Any thoughts what this thing might run in the 1/4 mile?

 

Sorry not sure how that got there?
