    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!

    I don't have CATS and no CEL. I'm not sure if 2000 is any different but I didn't do anything special.

    No CATS and no mufflers? Damm you must have good ear plugs.

    Seems to be what most people say regarding cats and CEL. Just hope I’m not the exception. What year is your car?

    And I just don’t understand why a Viper would be anything other than loud and aggressive sounding. The entire car makes that presentation in every other way, why not in its volume as well :)

    My car is a '97. It's in my signature.

    Loud is nice but with no cats & mufflers to me it would be unbearable after 5 minutes. I don't have either but the turbos and my cross over cut out a lot of the drone so it's not obnoxious.
