Exhaust leak isb 325

Discovered exhaust leak on my Cummins ISB 325. Can someone identify part, what it is called, where to order new?

Coil looking piece incorporated into line that "T's" off exhaust manifold, wraps around valve cover and goes into intake from charge air cooler line.

One end of coil looking part appears to have broken off allowing exhaust to escape. It appears I may need to buy entire length of pipe rather than just the coil looking piece.

Thanks, John

egr cooler to turbo

Simple replacement, two marmon flange clamps, or take it to these people, they are good! Order the part should take no more than 1/2 hour to install it or go the easy route! It may be covered under warranty because it is an "emission" part. I would call and find out.
