Maybe back in the early 70's, but now engines are designed to work with them, and you aren't going get that much better gas mileage on a stock engine with the cat removed. Plus its not street legal in most states (that I know of) to be driving without one

If you dont replace it im sure your mileage will suffer more, I just replaced mine in Fresno after driving around with a P0420 code (other side from yours) and gained back a few miles per gallon. So yes a Cat will increase your mileage

When i had a flex pipe issue with my 2004 9C1 Impala,i just replaced the whole down pipe,flex pipe,and cat with a Magnaflow unit (its all one piece).The magnaflow unit flowed better and had a better over all design.

Out of all the mods i did to that Impala,the biggest gain i felt was from that Magnaflow unit.Also the MF unit was cheaper in cost than a OEM replacement....It was really a win win for me

For example: The stock down pipe had a U bend that really restricted exhaust flow,the MF unit had no U bend and was strait through.The cat looked better as well.Really good bang for the buck.

Hi longstand. Good idea if you just use a Universal Catalytic Converter.
