Well if you have dual exhaust you don't have a stock set-up. Or are you confusing this with 2 tail pipes? Any local muffler shop should be bale to patch up your stock set-up.

My 82 Z had true duals. Funny I should have kept the piping when I sold it.

The 82 model did have funky dual pipes but I am not sure how true dual it was. It was unique to say the least.

Yes it was Shifty.
BTW(kinda late)I liked your response in the Chevy High Performance mag. Way to inform them. I think it was that mag I have so many its hard to keep up. Either way good job.

The factory has used 2 mufflers with one cat on 3rd gens, the factory has used 2 cats with one muffler on 3rd gens.

But, the factory has never used 2 intermediate pipes on 3rd gens, therefore the factory has never put "true duals" on 3rd gens.
