Anyone had a CEL with catted Downpipe (No tune/piggyback)??

Active Autowerke are working on a SUPRA catted downpipe thats EPA approved and comes with no CEL guarantee.

Unchecking that "oem/catted downpipe" box simply re-enables the logic check for the rear cat efficiency. Basically undoes what the tune had programmed to deal with the CAT cels.

I have a JB4 installed with a Dp, I usually clear my CEL every other day, what I noticed is the car loses power when I do that, for the past week, I havnt cleared the cat CEL, and boy does the car feel stronger.
Correct me if I'm wrong, but clearing the CEL seems to reset the fuel curve from the DME auto learn, right?

Car should run the same even with CEL

Indeed agreed.
My question was rather ( will the ECU fuel curve reset when I clear the CEL or not.)

deleting the code makes no changes to the ECU adaptive memory. It simply resets the Drive cycles to have the emissions monitors be ready, What you're feeling is pretty much placebo. If you were resetting adaptations, then i would say yes, that will effect it. But youre just deleting a code.

Thanks for the response it's probably paranoia then . I need to hit a dyno asap.
