Utec's 2 step taking out my cat?
 

I have a Utec, fuel pump, and a Profec B spec II on my 2003 Evo 8. I had it tuned to 23.5 lbs and use to be able to launch the car with the 2 step with 12-17 lbs of boost. Now I am lucky to boost at 10 lbs and will only launch at 6-7 lbs. Do you think the 2 step took out my cat? Any other solutions you think I should look at? I only had the 2 step on for a couple of weeks until it got this bad.

Anyone in Colorado have a mid pipe or full exhaust they want to sell?

i just have my stock exhaust on the car.
