CEL with ZZP downpipe

[Foxbox]

Has anyone else installed a ZZP downpipe and NOT triggered a CEL?

I installed mine months ago and have put thousands of miles on my setup and still have no CEL.

I'm not complaining that it hasn't, just have always wondered why. I didn't touch anything in the EZflash software to disable the code either.

Anyone experience something similar?

I cant speak from experience but what might have happened is your car has a pending trouble code instead of just a trouble code. In which case your check engine light wouldnt be on but youd still have a trouble code. Im not sure but that may be the case

did you get the downpipe with a cat or catless?

Depends on when you got your trifecta tune. If it was over a year ago and you noted that you had a DP in anticipation, then they may have turned the code off for you. They used to do that before they added the EZ-flash DTC function.

Otherwise it just may be a fluke. I went quite a while before it tripped a code on mine. Then the CEL frequency went from every 400 miles down to every 50 or so.

Catless down pipe.

Still no CEL. I've had a tune since 400 miles (roughly two years ago now). Didn't specify in advance that I would buy a down pipe.

Pipe has been on my car for prolly 5,000-6,000 miles now I guess. Still no CEL.

Weird, lol.

Still have your second cat?
