ive been reading on here that if i can find someone to replace my cats with hiflow cats and eliminate the rear two that it will set off my 02 sensor, what do i have to do to eliminate that problem??

thanks for your help!

 

You need a programmer such as SCT XCal

 

so your going to throw a CEL regardless when you go to a pair of high flow cats ? i was unaware of this...thought that had only happened in a few cases...where mileage and wear and tear was high

 

so i have to get a custom tune and tell them that i have my rear two cats eliminated and they can write me a code??
