LB7 Downpipe

(1 customer review)


Brand: ProFab Performance


Finally, an affordable high flowing down pipe for the LB7 Duramax. This one WILL fit the emissions 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.


Not legal for sale or use in the state of California.

    Fitment was great, has held up very well to the heat. Has held up better than the other aftermarket LB7 downpipes I have used.
