mfg Posted October 19, 2015 Report Posted October 19, 2015 The standard (catalytic converter equipped) factory exhaust system, as found on the 305CI '83 Avanti, is the same system used by the factory on the 305CI '85 Avanti...EXCEPT for the exhaust deflectors!.......True?
mfg Posted October 22, 2015 Author Report Posted October 22, 2015 Answer.....Although the '83 and the '85 Avanti exhaust systems are similar in layout, the '85 system is more refined with gentle bends in the pipe behind the cat....a less restrictive setup! Answer to question....FALSE! PS....and yes, the exhaust deflectors are different also!
