converter or not?
 

When I get my headers on and my exhaust redone, should I leave the cat. converters off or not? In the county that I live in TN we do not have inspections, and my se light is on and the code is for the front left converter. I can get the part thru gm at a little above cost but that is still about $425.00. If I leave the converters off and reset the computer will the se light come on because there are no converters?

Ditch the converters. For the computer you can get O2 sims so that the PCM thinks the car still has one. I think a mail order tune can do that for you as well.
