Did the 1989 camaro iroc-z have true dual exhaust?

Answer 1

not a true dual exhaust. most cars had two piped that fed into a single catalytic converter, then a single 3 inch pipe out and over the rear axle.

some cars had an option of "dual exhaust" where each exhaust manifold fed into its own catalytic converter, then into that same single 3" pipe.

some guys have fabricated true dual exhaust systems for these cars....it takes a lot of work to get two pipes over the rear axle and out the back of the car, but it is possible.
