Car: 92 camaro 305
havent put everything in, but im gonna do it all at once, what i have waiting is, a 276hr-14, comp controled, hydroller 276/290-220/230-.510/.510-114 cam, 2 power pulleys, vortec heads, edelbrock performer intake, custom tbi and custom cold air
im thinking about getting the american thunder exaust, which would be the best and with what headers? cat or no cat?

 

I hope you visit the TBI board to make sure your combo will run. SOunds like it could be great pending you have done everythingto those heads to accept that cam. Along with all of the tuning and fuel you will need. I would go with a set of Hooker 2055's for your set-up and cut the tubes off and go without AIR. it is not worth it in my opinion to go without a cat. They don't rob any hp and can be had fo really cheap. A quick search will help you determine what headers and cat-back you should go with.
