To be honest I have never ever seen another single wall OEM downpipe apart from this one. It may be extremely rare - some of the most knowledgeable people in the German crowd I know of have expressed interest in buying it from me.

You might be having in mind the pictures of the early downpipe I posted on the PCGB forum?

From what I have found, the factory transitioned from forged rods to cast rods during MY89. I have seen late production MY89 M44/52 engines w/ cast rods. Early 89s have forged rods. I do not know by what serial/VIN number the transition was made. I think most will say that MY90+ RoW engines all used cast rods. PET also matches this.
I recall some others also commenting on having torn down mid to late production 89 motors and have found cast rods.

Milledge also said that the early NA 944 forged rods were inferior to the turbo forged rods. Early '83 engines and some '84 automatic engines had forged CROSS-drilled crankshafts from the factory! 968 engines have two versions of lightweight forged rods.

I still have the original factory downpipe off mine if you want one to gut.

Thanks I'll bear it in mind, I'd have to make a jig so the orientation and length is maintained, and depending how good the weld is inside the flange that may be a pita to cut through, another problem may be not being able to get the inside tube out without scrapping the outer one.

OK, maybe someone here (Lart) can tell me which year 951 forged rods will work in a 1992 "968". I have a locked up engine to tear apart to find out what is wrong inside it. I hope for the best, but expect the worse. The 92 968 had poor rods as most people already know. I know the engine is not hydro locked. Any help is most appreciated.
Cheers,
Larry
