I just installed the Hooker 2055 headers, 3' catco cat, and 3" Hooker catback on my car and was wondering since the exhaust is capable of flowing more air now, if I would have to do anything to the prom to compensate for this? My friend told me I could burn up my exhaust valves if I didn't. So since I know nothing about this stuff, I figured some of you guys must have the same set up and can help me out here. Thanks in advance.

 

Ive never, heard of anyone ever burning up their valves. Used to hear that all the time with open headers too. I believe its an old wives tale. Heard that it can happen, but, never saw, or heard that it actually did. IMO.

 

alright, cool. that's what i thought too. so i don't have to worry about touching the chip, everything should be just fine?

 

I don't think an exhaust valve could get damage like that. Maybe if you had a turbo.

GM's programming is not a perfect tune, even on a stock vehicle. THey used simulations and a group of "average" test cars to mass produce the programming in your firebird. Sure, they "should" have fine tuned each vehicle. That's not cost effective though and nearly impossible(considering the volume of cars sold each year). Point is that you can reprogram the computer to gain HP, reduce emissions and increase MPG on a stock car. Any modifications done will just move the calibration further away from optimum.
