After a long a painful process of repairing and replacing a lot of parts in my WRX, I have finally got this thing working. I am now just looking for some advice on one last repair I have to make before relocating to a new state.
The car was purchased with some sort of aftermarket catless downpipe. In my current state this isn't an issue and honestly I can live with the cel it produces, but I am about to move to a state that does cel Checks and a sniffer test. With this catless downpipe I figure I would fail such a test, so flashing the ECU wouldn't fix my problem alone. Anyone have any experience with this? Also If I go ahead and replace the downpipe, any ideas on where I could pick up a stock downpipe with cat (I hear tell of a magic place that has them available for fairly cheap)? Or is it possible that an exhaust shop may be able to add a cat to the existing downpipe, and if so how do I know which cat I need for the downpipe (front or back)?
I apologize in advance, prior to buying this WRX I knew nothing about cars. Nothing at all. I learned a bit, but now that I am looking at the exhaust I am quite a bit lost.
Any help is appreciated!
