On my 85 Berlinetta, the pipe from the cat to the muffler is completley rusted, and holes keep cropping up. the muffler looks alright. I wanted to take it to a custom exhaust place and get a cat back, but my mechanic says its a waste of money. that pipe costs 44$, and he wants to reuse the muffler. Should I do this, or go with the aftermarket? Also, are there any aftermarket hi flow mufflers that will connect on the stock location to the origional exhaust tubing?

 

Any cat-back exhaust system should contain the new piping you need.

With a 2.8 you won't get much of a power gain, and the noise might get annoying with something aftermarket.

Personally I'd save the stock muffler and just put new piping on it.

 

fair enough
sounds like that is the easiest route... ill take it thanks man
