Freightliner Cabover Chrome Stacks & Tops

Frequently Asked Questions About Freightliner Cabover Chrome Stacks & Tops

What exactly are exhaust stacks and tops, and what do they do?

Exhaust stacks are the vertical exhaust pipes that route engine exhaust up and away from the cab on your Freightliner cabover, while stack tops (also called rain caps or top sections) attach to the top of the stack to cap it off, add a finishing look, and help keep rain and debris out of the exhaust system. Together they complete the exhaust system's appearance and function on classic cabover models.

Will these stacks and tops fit my specific Freightliner cabover model?

Fitment can vary by model year and configuration, so it is important to check the diameter, length, and mounting style listed on each product page against your truck's current exhaust setup before ordering. If you are unsure, comparing the measurements of your existing stack or referencing your truck's exhaust specs will help ensure a proper fit.

What materials and finishes are available, and how do I keep them looking good?

Most stacks and tops in this category are made from chrome-plated steel or stainless steel, offering a bright, reflective finish that stands out. To maintain the shine and prevent corrosion over time, regular washing with mild soap and water is recommended, along with periodic polishing using a chrome-safe cleaner, especially after exposure to road salt or harsh weather.

Do I need any special tools or professional help to install a new stack or top?

Basic installation typically involves clamps or slip-fit connections, so many customers are able to install stacks and tops themselves with common hand tools. However, if your setup requires cutting, welding, or significant modification to the existing exhaust piping, we recommend having a qualified diesel technician handle the installation to ensure a secure and safe fit.

Are chrome stacks and tops legal for on-road use, and are there any exhaust regulations I should know about?

Exhaust height, routing, and emissions equipment are subject to state and federal regulations, including DOT rules, so it is important to verify that any stack or top you install keeps your exhaust outlet at a compliant height and does not interfere with emissions components. Since regulations can vary by jurisdiction, check with your local DOT office or a trusted mechanic if you have questions about compliance for your specific truck and operating area.
