Manifold to H-pipe connection different between years?
I know some setups had the "pup" cats and the LS1 vs LS6 manifold changed as far as materials. And I know the Air tubes were changed. But do the midpipes bolt right up between the different years? For example, would a 97 manifold bolt right onto an 04 with the exception of the air tube and dip stick thing?
I've searched and searched and all I get are threads detailing the air tube differences and the cat configuration. I just wanna know if they'll actually bolt up. Thanks in advance for any help
Short answer. No.
I think there are three different configuration. I remember reading this, but I didn't save the link. The midpipe needs to match the manifolds being used. Not sure which years are compatible. I'll try to find the link.
