I am looking for a exhaust elbow for a 2003 standard out put engine. It's the one that is 4" from the turbo to a 3.5" down pipe. Does anyone have any idea where to find one,? Or even a part number? The dealer only sells it with the turbo.

 

I have one laying around that came off an 03 HO. Seems to be 3.5x4”?

 

I pulled this # from a local ad selling one

 

The one I have is marked Holset 3593384. I know it came off a 2003 HO (555) which if I recall correctly had a 3.5” pipe partway back, but maybe had a different turbo than the SO.

4035656 I believe was the elbow used on 05.5-07 5.9 600

Anyhoo, let me know if it will fit. Some surface rust from laying on the shop floor.
