What year exhaust manifolds bolt up to our trucks? Is there any way a manifold off of a 6.7 will fit? I know it has the egr plumbed into it.

 

You need a 12v one. I think the 24v will bolt up, but the ports are different.

 

Has to be 12v up to '98

 

12v is the easiest. 24v will work with lots of porting. Commonrail manifolds won't work as the downpipe would run through your firewall

 

yeah the 3rd gen manifolds are different, they have the flange that connects to the turbo farther back, so its like 2 ports, flange and then the other 4 ports instead of havin it centered with 3 ports on each side like on our trucks.
I've heard the 24 valve manifolds usually crack so just heads up, my friends dad has one and its cracked, and its all stock

 

12V port is rectangular, 24V and common rails are round.
