Peterbilt 367 Elbows, Piping & Comp.

Frequently Asked Questions About Peterbilt 367 Elbows, Piping & Comp.

What are these elbows and piping components used for?

This category covers exhaust system components for the Peterbilt 367, including elbows, pipe sections, and related fittings that connect the muffler, stacks, turbo outlet, and other parts of the exhaust system. They're used to route exhaust gases from the engine through the aftertreatment system and out through the stacks.

Will these parts fit my specific Peterbilt 367 without modification?

Fit can vary depending on your truck's exact configuration, including engine make, model year, and whether you have a factory or aftermarket exhaust setup. We recommend checking the listed specifications, such as pipe diameter and overall length, and comparing them to your existing part before ordering. If you're unsure, having your VIN and engine details on hand when you contact us can help confirm compatibility.

What materials are these elbows and pipes made from, and how do they hold up?

Exhaust elbows and piping for the 367 are typically made from aluminized or stainless steel to withstand high heat and resist corrosion over time. Stainless steel options generally offer better long-term resistance to rust, especially in regions with road salt or high moisture, while aluminized steel provides a more budget-friendly option with solid heat resistance.

Can I install these components myself, or do I need a shop?

Many elbows and straight pipe sections can be installed with basic tools if you're comfortable working under the truck and have experience with exhaust systems. However, because proper fitment affects both performance and safety, some drivers prefer to have a shop handle the installation, especially when cutting, welding, or aligning multiple sections is involved.

Do these parts affect emissions compliance or warranty coverage?

Exhaust components that alter the factory flow path, such as replacing sections ahead of or within the aftertreatment system, can potentially affect emissions compliance depending on your state and federal regulations. If your truck is still under manufacturer warranty, modifying the exhaust system with non-OEM parts may impact that coverage. When in doubt, check with your dealer or a compliance professional before making changes.
