Hi everyone. I wanted to post a new thread about this because everything I was reading was from over a decade ago. I will be removing the cats on my 2000 ACR on the 20th and wanted to know if there is any updated information on where to get what I need to make sure the CEL doesn't kick on? I know a lot of people have done this so it has to be easy. We have no emission worries in OH and the car already has the mufflers removed. Once i get this done I assume I will get it tuned so the fuel map matches the open exhaust. I've read old threads about a Vtec-1 but nothing recently. Roe Racing stopped selling the sensor bypasses about 5 years ago according to them. Thank you everyone!
