Duramax Diesel Exhaust Mods, and Stuff*

Instead of the crank case venting into the air intake, it reroutes it so. It vents down under the engine, like a big rig.
I thought as much. I will look into it. If it is a clean install, I might do it
It's literally just buying some hose, attaching it, and running it to where you want it, and plugging the hole in the intake... So it's as clean as you want it to be, lol.
A lot of guys run tbe hose into the frame, so when the odd oil drop comes out, it doesn't hit the ground. Your nose dictates where the end of the hose is.
That's a lot of blow by, and that's bad, lol
PLAN B!
-Retain the Cat. Retaining the Cat Converter will take all the stank out of the exhaust. i was not aware of the separate catalyst on these trucks. I am a big fan of DOCs. I sold a ton of them, and they really clean up the exhaust, and have little to no restriction. I can get a Cat Back stainless system, with a resonator, and will sound good, look stock-ish, and burn even cleaner without that eye-burning stank.

Stock cat piping is like 2.5"...
But with the cat still in, just the DPF out, I put 468hp and 850lb-ft to the ground...

Is it really that small?? Shit. Man, I really want to run a DOC. I suppose I could get a 4 incher, but they are like $800.
I also ordered a roll of 307 stainless wire so I can weld it all in, and ditch those stupid looking clamps.
Might be 3" but I'm pretty sure it swedges down to 2.5 in there.Stock cat piping is like 2.5"...
