Default lt1 manifold interchangeability

Attempting to sell the exhaust manifolds off of a 95 lt1, I want to know what years these things fit? will they fit 93-97 or are the newer lt1 manifolds different due to the different y pipe setup? Thanks!

The 94-97 exhaust manifolds on the 6 speed are different from the auto's. That's what ive seen so far.

But the 94 auto's had same manifolds as the 6 speed.

I don't know about the 93's.

After doing some ebay browsing, most I have seen is that 94-95 lt1 manifolds are interchangeable

Only for the 6 speed cars, because they are both federal emissions and have same type of manifolds.

The 95+ with A4 that are CA emission have slightly different manifolds. The thread at the air pump check valve pipe into manifold is a different size, and the manifold flange is different.

Just like to point out all the 93-97 exhaust manifolds are interchangeable but, the correct manifold that came with the car depends on what manifold you are looking at. There are more than one type of manifold so I would be specific when you tell the seller what it came out of.

If your 95 is Auto then they would be same threw these years 95-97 auto exhaust manifolds
If your 95 is 6 speed then they would be same threw these years 94-97 T56 exhaust manifolds.
