Hi
I’ve had the fault code P0420 on my type r which as I’ve read it’s a good chance the cat is on its way out.
However I have a piper catback exhaust fitted, but(excuse my naivety) would there not be a cat included in that system or might that system be causing the sensors to read wrong?
Either way what advice would you suggest to sort it, replace sensors, replace the cat or is it something stupid as fitting a spacer in the lambda?
Thanks for your help guys
