LMC Truck offers a complete mandrel bent single exhaust for my 70 Chev LWB Fleetside for $99.95, and that includes a glasspack and all the correct hardware to set it up. They claim it flows 20% better than stock. When I do the rebuild I'm almost ready to do I'm going to do some semi serious work on the head. If I clean up the manifold real good inside so it matches the ports and is correctly polished inside that might make another 5% improvement in efficiency. A 25% improvement in efficiency for $99.95, and a couple 3 hours work, would be a heck of a deal. Think it'll work?
