What is the part # for the Y pipe?

[sly1types]

I have found 2 different part #s for the Y pipe. I have a leak in the passenger side flex joint above where the EGR delete pipe is.

Which one do I need?

5C3Z-6K854-BA
5C3Z-6K854-CA

This one has the CA#
OEM LH SIDE TURBOCHARGER INLET PIPE FORD F250 F350 F450 F550 EXCURSION 6.0L V8 | eBay

This one has the BA#
NEW OEM LH TURBOCHARGER ADAPTER ASSEMBLY FORD LINCOLN MERCURY #5C3Z-6K854-BA | eBay

Thanks for the help!

5C3Z-6K854-CA is the part you need for your 07. the other number is for an earlier year model.

the early ones had the heat shield bolted to the pipe, the later ones have the shield bolted to the motor. My 06 had the shield on the motor. I strongly suggest not replacing with the stock part. Elite Diesel makes a better quality replacement for $$$ or I made my own for $50. See Really annoying whistle just started, help!
