Default Removing UTEC - What effect on ECU?

I have a PDE Up-Pipe and TurboXS TB Exhaust. I've been running their UTEC for about two weeks. I've decided to purchase the new STI and am getting my WRX-02 back to almost stock condition. If I remove the UTEC and keep the up-pipe and TB exhaust will I have any problems with the stock ECU?

Your ECU will work just fine.

You may get a CEL - but the car will run fine.

If you do get a CEL - either put the upipe and TB back to stock or you can do the resistor mod which will fool the stock ECU.

P.S. I am currently running my car with the vishnu uppipe and turboback without engine management and my car works just fine. I did have a CEL for the cat, but it disapeared after a couple hundred miles.

I appreciate your reply. I think that I should be OK. I don't have the original stock Up-pipe and don't really want to locate a used one. I plan to get the UTEC on E-Bay this week-end. Thank you.

If you are not getting CELs now, you won't be getting them without the UTEC as the UTEC does absolutely nothing to prevent them. Do yourself (and the next owner) a favor and leave the uppipe in.
