Finally, an affordable high flowing down pipe for the LB7 Duramax. This one WILL fit the emmisions LB7 also and is a true 3" diameter mandrel bent. It is also tig welded and ceramic coated black. Expect better all around performance & lower EGT's from this. You can add heat wrap below if wanted.
This down pipe does not have a support tab. We do not believe it is needed.
