Y pipes, others

other part of the exhaust. In one area it's pinched flat almost half the
diameter. Even just replacing that would free up the flow by a large
margin.
        My local muffler shop quoted me $350 for a complete system; Y
pipe, free flow cat, 3" cat back through a "turbo muffler", out the
back. If I could get a set of JBA headers for $250, I'd have a decent
system. By the way I do not condone taking the cat out of the system
completely unless your truck will never see street use. I like breathing
something that comes close to O2.

        Did anyone get my post on a one piece drive shaft? Will the one
from a 90 CC with 4spd OD trans bolt up to the V8 truck??

        Another thought just filtered through the fog in my brain. There
is a piece advertised for GM TB's that fits between the TB and the
intake. It raises the TB about an inch, and the claim is that it gives
about 10 more HP, with similar Torque increases. Would something like
this work for our Dak's?? Or is this another GM gimmick to smoke the
public?? ( The ALL new 99 Sierra P/U. Looks the same, smells the
same.....).

        Any more progress on the shift kit for the 4spd OD Trans??

        This is an excellent list. Thanks for the hard work Jon.
