Have an 05 WRX here just failed on emissions high idle lambda 1.07. CO 0.01% and HC 12ppm. Exhaust leak before my secondary lambda sensor is the culprit. Rather than fixing my stock exhaust, I have a complete new 3" turboback system. Has anyone on here with a newage pass nct with just the up pipe cat on its own? No downpipe or centre cat?
 
Eh no.

We can lend you a catted exhaust system for NCT. If we are fitting and refitting.

You won't pass with just the up pipe cat. You need the main cat at the back of the turbo in place to pass or a sports cat other wise your wasting your time
