A true dual system on the 1984-1997 Camaro (F Body) is not a pretty picture.
Due to the pan hard rod and torque arm that got introduced with the newer style Camaro's it makes a symmetrical "True" dual exhaust a SERIOUS undertaking. You would literally have to cut and fabricate to facilitate a symmetrical dual muffler setup.
Now, there is the later model (96-97) SS models that utilized a "Dual" exhaust however the pipes are rather small and run side by side where the traditonal exhausts would run. I think these style exhaust still run into a single muffler however and then branch out into duals.
I think if GM would have built the 1984-1997 Camaro's and Firebirds with a body more accepting of a TRUE symmetrical "Dual" exhaust we would have seen about 5-10 HP more in any given 305/350 configuration. I should also mention the famous crackle that that goes with the current configurations would also have been replaced by a more deep and tuned sound.
Still, a nice 3 inch into a high flow muffler such as a flowmaster has a real nice sound, and flows pretty good. I suggest shorty style headers if you plan to drive the vehicle every day on the street. Long tubes flow a little better and offer a slight improvement in sound but are a real bear to drive around on city streets without them hitting the ground when driving up inclines, speedbumps, or high spots in the road. I have had good success with the Edelbrock shorty style headers, they are nice and thick where they meet the head and keep gaskets better than the less expensive kind. It really does not matter brand you go with, all the headers must be dimpled on the drivers side to allow clearance for the steering shaft. I suggest marking the contact area, then heating up the tube area and using a 3/4 inch impact socket to dimple the area. Just lay the socket on its side using an extension to hold it and wack it with a hammer. It will leave a nice clean indentation that should clear the steering shaft yet still look professional.
Hope that helps. I do have photos if you want to look at diffrent kinds of headers/exhaust systems.

And There Is just One More Q>>>>>> I have Had Some Chances To Buy lt4 heads ? My Lt1 Is Getting Tired >>> Port The Lt1 heads And Get them worked on Or Buy Some LT4 Heads? Besat Bang For The Buck?
I dont care what LE says about stock heads, LT4 castings are superior.
The new Edelbrock LT4 RPM heads are also VERY sweet with 2.02 valves and have ports matched for their LT4 air gap intakes. The Edelbrock LT4 RPM heads also come with bee-hive springs good to .600 lift. The amount of money you would spend to get a set of stock heads to LT4 specs and bee-hive springs you might as well get the Edelbrock heads.
If you plan on using nitrous then you can get away with a set of home ported and modified LT1's because you are forcing air in, however the LT4's will have better flow ratings and perform much better than an LT1 head naturally asperated.
Check out the LT1 vs LT4 thread, it has cut away images of the difference between the two. If you got the cash though, I would go with the Edelbrock LT4 RPM heads, they are about the BEST I have ever seen.

The Edelbrock LT4 RPM heads are MUCH better than the LT4's.
This is not a super busy forum, even though we see 70,000 hits per month. LOL
To do a true symmetrical dual exhaust with two mufflers your going to have to channel the floor and cut out the foot well for your rear passengers seat. Additionally you would have to do away with the panhard rod suspension in the back. To do it right anyway.
Otherwise just pick up a 1996 SS exhaust system, thats as close as you would get to true duals without cutting things up.
Good luck.
