The Exhaust on it that you are seeing is referred to as a 2 Out The Left exhaust... All Stainless steel muffler, And 2 90 Degree Stainless steel tail pipes cut on an angle to resemble tips...'
It is a Great muffler, It is basically a 1 In /2 Out straight through muffler with no chambers in side of it, the only thing inside of it is the piping is perforated to quiet down the exhaust a little bit..
One of the best flowing Mufflers can get for these cars...
The Exhaust system was made and designed by SLP they used the same exhaust on 96,97 Camaro SS's, Firebird GT's and 96-2000 Pontiac FireHawks..
The only thing with the 2 out the left exhaust's is certain years, the EPA Mandated that GM quiet the exhaust down a little bit because it was loud at certain rpm's and during drive by test's ...
So certain years have a Silencer installed in one of the 2 tail pipes to quiet the exhaust down a little bit referred to as The Cone Of Silence..
All you need is a straightened coat hanger and stick it in both tail pipes to check and see if it has it..
If it doesnt cool the exhaust screams..
If it does have it No big deal it can be removed very easily..
That Looks like this..
