Mate with new HFC's on his 57 plate today failed his MOT on emissions. Before having to pay to swap back to OE cats, is there anything we can recommend to try first?
Been thoroughly warmed and even a fuel cleaner put through.
Nice modification with ease of adjustability too.
I'd say the whiteline lowering springs probably have the perfect drop for the 350z. Tein isn't enough and eibach seems too much. Look forward to the next update.
