OK after owning a few third gens and a few different exausts i have a few different opinions. the main questions people always ask me is: How do you install true dual exaust? and: What is a cat-back and how does it go into your thirdgen? and: What are dumps and why do you want them?
Well i have SOME of the answers here now for all to see! I've Created skematics (CRUDE skematics) but they should get the idea across.. NOTE: these skematics are NOT for installation instructions, they are merelly ideas I have TRIED and that WORKED on my Thirdgen Camaros....
Now for the first one!

THis is a CAT-BACK that is Typified by companies like Flowmaster, Dynomax, Basically any vendor making a cat-back for a thirdgen camaro. it is the most common one. The area highlighted in Orange are the parts you receive when you order an entire cat-back from flowmaster. the one shown is known as the "American Thunder Series" by Flowmaster. Its a 3" cat-back and I've installed it on my STOCK 1989 RS camaro, AND gutted the catylitic converter. Note I've experience no loss of torque, only an increase in high end horsepower and looks from other people.
NEXT is the FIRST exaust I've installed on my 1983 Z-28 Camaro, which i later changed since i didnt think it was loud enough, as the "custom Y-pipe" restricted too much sound and exaust.

all in all it worked quite well, for a while. very loud, very strong. very cammed up engine. (comps 292 Cam, 2.02 intake/1.60 exaust, 225-230 dur. @ .050 lift, forged pistons, etc...)
This is true dual Exaust! (for me anyways)
Next is my Current exaust for the above 1983 camaro. its also true dual, but there is no equalizer H-pipe since the exaust ends under your car seat!!!

Note: VERY LOUD!! had to change my driver and passenger Windows to plexyglass because they began cracking under the thump of the engine!!

Well I hope my little lesson proved valuable to all those tempering with their exaust.
In case the pictures dont show up for you, here are the links in the order in which i explain them above:

3,000 dollars is it really worth that much money over the stock style set up?

 

$3,000 is for that fully polished stainless steal and fully coated headers, AND all done by an expensive shop.

Many people have done it $500 or less.
