This complete exhaust upgrade pairs HSP's one-piece cast manifolds with heavy-wall 304 stainless up-pipes for the 2001-2004 LB7 Duramax. It clears out the factory restrictions that choke turbo response, drops your EGTs, and adds the durability the stock cast pieces never had.
Why run the HSP cast manifold and up-pipe bundle?
The factory LB7 manifolds and up-pipes are notorious for cracking, warping, and leaking bellows, all of which kill spool and reliability. This bundle replaces both sides at once with high-flow one-piece cast manifolds and reinforced 2 inch 304SS up-pipes, every piece ceramic coated to 2,000 degrees for serious under-hood heat management.
