1. Who is the go to for 68205983AA OEM parts?
2. Any one running aftermarket BD or Dorman manifolds?
3. Why did you go from OEM?
4. Any other choices to consider?

Are they different from the pickup manifold? If not grab a used one from someone who swapped it out.

Yes.....the cab & chassis exhaust manifolds are indeed different than the pickup variety.

Are you experiencing a warpage issue in regards to exhaust gaskets leaking and sounding off like multiple bottle rockets?

I figured they were but I have an unused one sitting in my barn that needs a new home.

I have a whistle that you can only hear when the exhaust brake is engaged, no noise or smell otherwise. It is an 8 hour job to fix, so the parts are the cheapest cost breakout of this repair and labor is the most.

Good chance you just need six gaskets; get the correct ones from Cummins or a dealer.

When the exhaust manifold is off.....check it for warpage. In the event it is warped some....a good machine shop might be able to true it up some.

Going with OEM again. I question whether the two-piece BD design will leak and Dorman has never been known for high quality.I cannot spend 8 hrs on this repair and not have the parts I need to get it back together. If it does turn out to just be a gasket or fastener issue, I will have a used manifold for sale. FYI: Cab and chassis parts are not sourced quickly, so plan on preemptive purchases if you cannot handle down time.

You could have a machine shop skim it quick if you have a second vehicle it would not take a decent shop more than 30mins max
