OK, this is me doing my early research. I am getting ready to "pull the trigger" and order a ZZP DownPipe w/ High Flow Cat for my '04 Monte Carlo. As I understand, this will more then likely cause the car to throw a PO420 service code.

The solution I've seen is to have someone with a tuner erase that code from the car's computer (otherwise it will pop up frequently.

My question to the folks here, is there anyone near Cleveland Ohio (I actually live in Mentor Ohio) that would be willing to help me out with this situation?

I'm looking to line someone up for after I install this mod OR perhaps just erase the code before I even order the mod.

Thanks everyone!
