Peterbilt 389 Glider Exhaust Kits

Frequently Asked Questions About Peterbilt 389 Glider Exhaust Kits

What is included in a Peterbilt 389 Glider Exhaust Kit?

Most kits include the exhaust stacks, elbows, mounting brackets, and the hardware needed to complete the exhaust run from the turbo or muffler outlet to the top of the stack. Some kits also include heat shields or clamps, but the exact contents vary by kit, so always check the product listing for a full parts breakdown before ordering.

Will this exhaust kit fit my Peterbilt 389 glider truck?

These kits are designed specifically for the Peterbilt 389 glider chassis, but fitment can still vary depending on cab height, frame configuration, and the engine or muffler setup used in your glider build. Compare the stack diameter, length, and mounting style listed in the product details against your truck's current setup, and reach out to our team if you are unsure about compatibility before purchasing.

What materials and finish options are available?

Peterbilt 389 exhaust stacks and elbows are commonly available in aluminized steel, stainless steel, and chrome-plated finishes. Aluminized steel is a budget-friendly option that resists rust reasonably well, while stainless steel and chrome offer a longer-lasting shine and better corrosion resistance, which many owners prefer for the polished look glider kits are known for.

Do I need any special tools or expertise to install these exhaust kits?

Basic hand tools such as wrenches, a socket set, and clamps are typically enough for a straightforward stack or elbow swap. However, depending on how your glider's exhaust system is routed, some cutting, welding, or fabrication may be needed to get a clean fit. If your installation involves modifying existing piping, we recommend having the work done by someone experienced with heavy-duty exhaust systems.

Are these exhaust kits legal for on-road use?

Exhaust stack height, placement, and noise output are subject to state and federal regulations that can vary by location. It is the installer's responsibility to confirm that the finished exhaust setup meets applicable DOT requirements and local noise ordinances in the areas the truck will be operated. Check your local regulations before finalizing your stack height or configuration.
