What year cars would 94 Camaro LT1 stock manifolds work on?

 

both the exhaust and intake should fit all years of ltx model cars. you'll want to use the 94 y-pipe with the exhaust manifolds if that's what you're referring to.

intakes should all be the same, there were no updates to the intake until edelbrock made the air gap intake for the ltx cars...there is one other manifold that's like 1400 that is a polymer intake, like the lsx but designed for the lt cars.

 

I apologize, I was talking about my stock exhaust manifolds. I was going to sell them and was just trying to get correct information on them.

 

I believe the exhaust manifolds will fit 94-95s only (as a direct swap).

 

my 97 was the exact same as my friend's 95 with single cat. so, for me and him, they were direct swaps.

 

Were the AIR fittings the same?

 

The AIR fittings are different. Single-cat manifolds use the equivalent of an M22 thread, dual-cat are more like M18. The flange on the drivers side exhaust manifold is different also. The dual-cat cars have a large triangular 3-bolt flange that is used to mount the dirver's side car. The single-cat exhaust manifolds don't have that.
