hey all,
reason why i am posting is cause i have a series 2 au falcon forte, has done only 59,000kms and ive decided after getting a exhaust system for my ba xt, id get one for the AU, and was wondering if you could help me on the right size of cat for the AU as i dont want to cause back pressure. On the ba i have pacemaker extractors 2.5inch magnaflow cat and 2.5inch redback system. Would a similar system be the best way for the AU as in pacemaker 4499 2.5inch magnaflow cat 2.5inch redback. or can i get away with a 3 inch cat. any advice would be great. Also i know ba's have 2 different extractors from pacemaker low down and high end, whats the best option for an AU low or top end? cheers guys regards Simon
