Just wondering if anyone has seen any variations of tube manifolds for diesels? I have searched around, but cant find anything. Dont know if im searching the wrong area or if the area hasnt been explored yet.

For Cummins I know of at least 4 different manufactures currently. Including Dave@Passenger who is a member here. For Duramax there are two or three. I am not up on my powerstrokes enough to know for sure if there are any available, but I would imagine there are.

Dave was making some for baja 1000 Cummins chase trucks so you know they are top quality.

I wonder what kind of power that makes over a stock manifold. My brother is about to start modding his new truck, and were gonna build a ex and a intake mani.

I think it is more about spool and egt's than power but pm "passenger" on here and chat with him about it. I know Dave personally and he is great to deal with.

Dave is a nigger. He comes to your house gets you drunk, and convinces you to let him have the motor out of your car. He then takes said motor and makes more power on that style of motor then anyone else ever in North America.

Oh and I know Dave's mom personally.

Hey shutup about my mom slutbags

Funny story about that engine I took from you Brett, you know how I got that cylinder head I did up, made in mexico under the Kolbenschmidt license, and than slapped on that block, and later blew that engine from shitty pre cups? K well it turns out I actually had an OEM German made head sitting here I could have used, so that failure was totally unnecessary, gay, I just found the German head yesterday.

Yeah I have made a bunch of tubular exhaust manifolds for some baja1000 race and chase trucks, 4 variations, done lots of testing. Also have extensive experience porting, and milling the sides of the heads off to remove the integrated stock intake manifold.

All in all, cummins are train/tractor engines, but you can get some decent response out of them with some work.

Gay, is right, I guess you better build another one.

Have any pictures of the other manifolds? What kind of performance do you get out of the tube manis? What do you sell a manifold like that for?

Maybe, I'll look around. Not sure if I had a digital camera then, better odds seeing if my friends have any pics.
Performance was good, biggest thing was response, woke the engine right up, no more waiting for the power to come on. I think I sold some manifolds to some guys not from the team for around $1600CAD.
