Just installed the above as I managed to pick one up from a guy who had sold his 968 over here in the UK. I have the air box mod and a better flowing Cat Back but alas no headers.
Does anyone know the difference between stage 1 and stage 2?
It certainly seems very smooth delivery, better than the Promax I had (which I think was faulty), also picked up a standard chip as I didn't have one either.
I would go for headers from Pete but believe they are only for LHD cars.....?
