Is there a reason GM went with single exhaust?

i reckon youre refering to the y-pipe? and im pretty sure its because the suspension gets in the way of the of dual pipes. which is why my bullets are dumped before the axle and my x-pipe scrapes over speed bumps.

It all started in 75 with the cat finding it's way onto the f-body. From 75 until 89 they only ran one cat so all exhaust gasses had to go through one pipe. Now consider the platform under your Z28 was basically designed in the late 70s and that will clarify why.

I always wanted to know this as well.
*Briefly off topic since the above member mentioned chassis** What frame/chassis is used in the late 4th gen's? Is it a carry over from something else or an older F-Body? For example like the stangs all the way up to 04 used the old out dated fox body chassis.

The fourth gen platform is pretty similar to the 3rd gen platform. My brother has an 89 Camaro and its very similary underneath. However his engine doesnt sit under the cowl

Despite of everyone complaining about this, including a lot of mechanics I kind of like it and Im sure they did this for a reason. Look how much forward the engines in stangs sit compared to our cars.

To get that slick windshield angle the designers had to extend the cowl over the engine.
And the Platform is basically refered to as the 4th Gen F-body (because all the other Gens are their own aswell). The only real thing shared between the 3rd and 4th gens is the rear suspension design. And the Single exhaust is due more to packaging constraints and peice costs.

The 98 WS6 SS "one on the left" was supposed to be the new version of the famous "two on the left" SLP exhaust but it didn't catch on and was dropped in favor of the Dual Dual SLP setup.

The floorpan is also common between 3rd and 4th gen. The passenger floor "hump" on a 4th gen is a remnant of the 3rd gen catalytic convertor cove.
The engine in a 4th gen isn't "back", it's just that the windshield's leading edge is so far forward. Like an Intrepid lol.

that may be the case but since they didn't change the car from the mirrors back there is a reason why an LS1 car would still have the hump since it was necessary for the LT1 (and apparently the early LS1)

I read somewhere the engines are under our cowl and pretty far back is to put more weight to the center of gravity. I am not 100% sure if that is the case but it would make sense.
The reason I asked the original question is because I have true dual exhaust that goes over my axle (Bassani) and I really love the way it sounds. But I dont think it is loud enough, but it could just be me since I was running two open cut outs with a big cam lol.
