Catalytic converter question.
I have a 2001 dodge ram 1500 4x4 5.2, the truck is from California so it has Cali emissions. I now live in Ohio so I do not have any type of emissions inspections. I have three catalytic converts one right after each exhaust manifold with o2 sensors before and after each one. Then at the very bottom a third catalytic converter right before the muffler it's a good size one too. I found a muffler guy who will cut that third one out and replace with a pipe along with a new flowmaster 60 series muffler single side exit after the rear tire just the the stock muffler did. He said he would also put a crime tip on. Would this hurt my low end, would I gain anything from this mod? So far I have put the 1.7 Harland sharps in and got an SCT tuner from Hemiefever. Thanks for the help guys
