Default 00-02 Stock manifolds.... are they different and will they fit my 98 TA?
I just bought a set of stock manifolds off of a 2001 Camaro LS1. I have a 1998 Formula with the LS1 and the exhaust manifolds are leaking bad. Will the 01 stock manifolds bolt up to the 98 LS1 Firebird? i can tell that they are a little different....

the AIR and EGR fittings are different locations and directions. also, the 00-02 passenger cats bolt directly to the manifold. so, not sure if the bolt angle is the same, or not.

They will not fit ddirectly to Y pipe. If I remember correctly they are slightly variated on the Y fitting (as in position of collector)

Pretty sure the Y-pipe fit is the same. The 01/02 do not have EGR and the AIR is in a different location.

The y pipes fit different. How does a manifold leak? Maybe you just need to change the gaskets?

The all thread where the nuts hold the y-pipe on are broken off. 2 on each side.
