up-pipe/down-pipe confusion

[BUCCaNOLES]

Stoopid question time. Does anyone have an illustration of the Duramax exhaust system? I've heard up pipe /down pipe. I bought a turbo back system but apparently that's not totally true. :doh:

The uppipes run from the exhaust manifolds to the turbo. The downpipe runs from the turbo to the front pipe. These bolt up near the starter. From there the frontpipe goes into the cat, then the rest of the exhaust.

Turbo bakc duramax exhausts are actually downpipe back. Turbo downpipes are available for the LLY and LBZ

So other than the downpipe back exhaust, the only other exhaust mods we can do is the BD Manifold and aftermarket downpipe?

Pretty much. unless you have some up-pipes made. I don't know of anyone who sells them. I don't believe you'll see much benefit from them unless you have a highly modified engine.

Cool My Duramax - Welcome to the new site!

built a set of log stlye manifolds and uppipes. They arent cheap but supposedly helped. However I think they might have not even gotten to production due to everybody being skeptical of them

Uuh... no. Rick and TxC were collaborating but have since parted ways. The ones on CoolMyDuramax.com are TxC's, I believe...

So the real point here is that Rick sells 'em too. Therefore... you have two choices. I've heard that both make an amazing difference in the engines...

But what do I know...
