Just received this up pipe off ebay. Just want to make sure it will fit my 2003 blobeye wrx before I try and fit it, and didn't realise classic and newage decat up pipes are the same but it does say it fits 93-07

Just checked it over and think I answered my own question, got a feeling I wasted my money as there is no boss for the Lambda sensor which I presume you need on an 03 WRX.

 

The Lambda sensor is in the manifold just before the up pipe, so you are fine for that. The EGT sensor is in the up pipe on the 03, which will bring up the CEL if not connected, but you have the option to either fit a resistor to the wiring to fool the ecu into thinking it is connected, or have it mapped out of circuit.

 

If you fit the pipe, you should get a map quickly after. The mapper can map this out.

 

Thanks for the replies.

I also have a decat downpipe so going to do a full decat and remap if I can find anyone to do it. Problem is, there is nobody on the isle of man who can do it so might have to come to the mainland to get it done sometime.
