2004.5 - 2010 Duramax Downpipe by ProFab Performance

This is a true mandrel bent 3″ diameter, ceramic coated, and heat-wrapped downpipe designed to fit LLY / LBZ / LMM Duramax trucks. 

Plus it's made right here in the USA!

Expect better all-around performance & lower EGTs from this downpipe.

This pipe does not have a support bracket because it is designed not to require one.
