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

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.


Where can you get a performance exhaust for a 93 Cutlass with dual exhaust?

Performance exhausts are usually custom bent and made by most exhaust shops.I have a 1987 olds cutlass and have used the Iroc Z design from the converter back .the muffler is an 80 series Flowmaster .It sounds really nice and it definitely helps the performance.Check in the yellow pages for people who custom bend their exhaust. As far as dual exhaust goes , the flowmaster is a single in and dual out sytle which keeps me emissions legal and gives the appearance of duals as well as the sound also.

On a v8 will single exhaust make more power vs dual exhaust without a crossover pipe if sized accordingly?

The more air that moves on the final stroke of a combustion cycle, the better the performance. If the single pipe from the engine is large enough, then yes, it can outperform an engine with a true dual exhaust with smaller pipes.
