I recently purchased my fairlady and I know, i still haven't posted photos, unfortunately weather has been horrible etc. Anyway I need to buy a pair of catalytic convertors for her. I got a horrendous quote for a pair from motex, however they also said it would be cheaper to buy sports cats. I just need them to beable to pass the mot. So not bothered about if they are reconditioned etc. Although I do need them to always be on as my luck isn't as good as others haha. She's an 03 model with chassis number: z33-001378 any help would be greatly appreciated.
