Default LT-1 Exhaust

What do you see when you look at this diagram ?



Looks kind of like shorty headers with a catalyst welded to the collector, I've never pulled one apart, is this what it really is ?

That must be a ZR-1. The 1992 LT1 has cast iron manifolds that look nothing like those in the diagram, with separate cats and a slip fit on the passenger side, ball type connection with 3-bolt flange on the drivers side. Also "bean scoop" exhaust tips, not the dual outlet.

Does anyone know if the ZR1 mufflers will fit a LT1? and how do they sound? Looks like they would have less restriction as there are 2 outlets per muffler unlike the 1 per muffler on the standard LT1 cars (my 95). I don't want the loud Flo-Master's resonance and I hear the ZR1 sounds awesome- how much of that is due to the mufflers?

PS The top pic looks like my LT1 mufflers and the bottom pic might be the ZR1- note the different part number for the resonators
