cat or not to cat???
what are the pro's and cons to having a cat or catless DP? Emmisions is not a concern of mine so leave that pro or con out. Im wanting a header and DP to bolt to factory exhaust. Which combo would you suggest and would it be catless or not??

Thanks
Tim

would this set up cause me to constantly have a CEL? i want to eventually have a header, DP, CAI, and OTTP stage 1. Can I do all that without getting a CEL?

Thanx
Tim
