    I have the catless version. But if you get a high flow cat with the downpipe you won't get a CEL.

    I'm in the process still of finding the right spacer combination to get rid of the check engine light with the catless setup.

    I have a 2.0l track edition with about 4000 miles on it ! i installed the cp-e downpipe and cannot for the life of me get it to not set a cel! i have tried defoulers, the simulator they sent me. I have tried different variations of the both of them. I keep getting a 140 code. I don't get the inefficiency code just the no activity code which is a two trip failure code! does anyone know what it takes to take care of this!

    I assume you have the catless version? Ive heard that the ecu isnt trickable when it comes to cats, something to do with the way its tests it. I have tried so many spacers and defoulers and I always throw a code, which for me isnt a big deal because I have the GReddy informeter and can reset it when I want.
