With all due respect to the much touted Borla system, I would like to know if anyone has bypassed the third catalytic converter and resonators? I have a muffler guy that thinks that will lower my back pressure a bit and give me the sound I want. The third converter is after the 2nd bank O2 sensor so it shouldn't affect the computer, right?
