Diesel trucks are all the rage now, and they aren't being bought only by farmers and construction workers anymore. Nowadays, it's just as cool to hear a turbodiesel spool up through a 4-inch exhaust tip beneath a lifted truck as it is to hear a big-block V-8 growl from a lowered one. The benefits of diesel engines have been touted repeatedly in Sport Truck, so we'll skip the part where we tell you how great they are and just show you some bitchen new projects to make them haul the mail. Check it out.

Hooker Headers Turbo-Back Exhaust System
Application: Dodge 5.9L Cummins Diesel Trucks
Hooker's new single- and dual-outlet turbo-back diesel exhaust systems are robotic-welded for leak-free operation. The system is mandrel-bent from 4-inch 16-gauge 409-grade stainless steel to resist corrosion, increase exhaust flow, reduce power-robbing backpressure, and lower EGT, resulting in longer engine and turbocharger life. All systems include a 7-inch round muffler with a free-flow perforated core, which exhibits an aggressive yet mellow big-rig diesel sound. All single- and dual-outlet systems include polished stainless steel 4- to 5-inch slash-cut exhaust tips. Hooker includes all necessary clamps, hardware, hangers, and comprehensive instructions written for the home mechanic who likes to turn his own wrenches.
