    Just about to that point now that i got to start figuring that one out. My current plan is to run the factorie style "Y" pipe and then do singel 3" after that with just a glasspack, but have it run all the way out the back. Does this sound like a good idea? the truck allready is set up for duals (has dual 2 1/4" till the muflers which are both blown up and missing tailpipes) but then id basicly have to buy twice the exaust parts to keep it dual. So what would you do?

    Are you going to be reving the motor to the moon? If not I would just use a highflowing 3" single system. If you are after some high end horsepower with a motor that size you will want something a little larger then 3" I would bet. Probably 3.5" or 4" exhaust or 2.5" duals.

    I have dual 2.25" exhaust on my K5 and it was cool for awhile, but now I wish I had a single 3" system. The duals take up to much space and cost to much when cats and stuff go out.

    Actually the single 3" flows better than dual 2.5's. more cross section area for the exhaust to flow thru.( i think. Im drunk right now and i cant really remember crrorectly)

    stock 78-85 c-10 diesel 350 pipes and manifolds, and they are dual from factory and one of the two manifolds has a blockoff that can be removed for use with a y pipe, i have a pair i can get you casting codes if need be, they are common,

    good luck

    I think you're refering to the olds diesel 350, those won't fit the heads. Personally I would go with the single 3 inch, especially if you keep the rpm under 4000 for the most part.
