RE: Cracked EM 2-piece, RS2, etc.
The 2-piece EM is for turbo 10V engines. It is a beautiful piece of work and is
an AWESOME flower of hot exhaust gasses. If you put one side-by-side
with a stock 1-piece 10V turbo EM you will be shocked at the difference
in port size and passage cross-sectional area! Makes the stock 10V turbo EM
look like a soda straw Vs a sewer-pipe.....
RS2 EM is for turbo 20V engines and is very different Vs 10V EMs.

I can never remember, but is the 2-piece unit made for the turbo MC
engines or for the N/A motors? I keep forgetting, but I think someone
mentioned that the 2-piece is for the 20-valve motors and so is the
RS2 manifold. The RS2 manifold I've been told is a 1-piece unit.
If for the turbo MC (1989 or 1990) 10-valver then what is the part
number(s) for it? Could never figure out how the 2-piece works to fit
into the turbo exhaust inlet. :)
If for the MC, then when fitting it would it be a good idea to match
the EM outlet to the turbo exhaust inlet? I mean, die grind (or
whatever) the rough ridges away and match the 2 flow units.
