i wanted to know what would be the loudest exhaust system for a 1986 iroc camaro, i want a header back system non/with catalytic converter it doesn't matter what ever's loudest. the car is all stock for now but i plan on doing some head work. thanks.

 

Probably straight duals or duals with bullet mufflers.

 

Exactly what engine do you have? There was no "HO" in 1986, except a very few L69's - seriously doubt you have one of those.

Loud, stock '86 with head work is a receipe for getting embarrassed by Accords.
