Catted downpipe and opf delete CEL

[sabin321]

Hello everyone!

If I install a 200 cel high-flow catted downpipe from armytrix with cat simulator and a OPF delete exhaust with Whifbitz OPF harness can I prevent a CEL from appearing or will it come up eventually?

I have an European 2022 Supra and I want to improve the sound while keeping my ECU locked and preventing EML. What are my options?

I honestly wouldn't worry about the CEL from a dp. If you have a jb4, just delete it when it pops up. You can also use the jb4 to check the codes periodically, to make sure it's still just the dp related code(s).

I bought an AA high flow dp, which is supposed to be no CEL guaranteed, but it still threw a CEL. Yeah, I can get it replaced at no cost, but then I'd have to pay for another install (I don't have the hardware to do it myself). So I just delete the CEL when/if it starts bothering me. It will typically stay gone for a few days before it pops up again.

Your armytrix has a cat simulator. You shouldn't even get a CEL. I haven't and I'm catless. My other car is a 200 cell and it didn't even need a simulator, just a spacer. No CEL either.

Good that you did go for that DP because that is literally the only way to prevent CEL on locked dme.
