Smoke Stacks

Smoke stacks deliver an unmistakable look and a deep exhaust note that sets a diesel truck apart. Also called vertical exhaust stacks, these tall pipes route exhaust upward through an opening in the truck bed or from behind the cab, leaving no doubt about what's under the hood. Whether you're building a dedicated puller, a show truck, or a daily driver with attitude, the right stack transforms both appearance and sound.

Most stacks are made from durable stainless steel or aluminized steel, with polished, black, or chrome finishes available. Common diameters range from 4 to 8 inches, with heights tailored to your setup—from a subtle bed-top exit to a full above-the-roof presence. Many kits include the stack tube, a clamp, and sometimes a rain cap, while others are sold as bare pipes for custom fabrication.

Before ordering, measure your bed or existing exhaust layout, check local noise and emissions regulations, and decide on a mounting style: stake pocket, bed-cut, or behind-the-cab bracket. Always pair with proper exhaust tubing and hangers for a secure, leak-free fit.
