International WorkStar Chrome Stacks & Tops

Frequently Asked Questions About International WorkStar Chrome Stacks & Tops

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

Chrome stacks and tops refer to the exterior exhaust stack pipes and the decorative or functional top pieces that attach to them on your International WorkStar. The stacks route exhaust up and away from the cab, while the chrome tops cap off the pipe, add a finished appearance, and in some cases help direct exhaust flow or reduce water intrusion when the truck is parked.

Will these stacks and tops fit my specific WorkStar model and existing exhaust setup?

Fit depends on the diameter and length of your current exhaust piping, as well as how your stack is mounted (behind the cab, under the frame, etc.). Before ordering, measure your existing pipe diameter and check the listed specifications on each product page. If you are unsure, our team can help confirm compatibility based on your truck's model year and current exhaust configuration.

What materials and finishes are available, and how do they hold up over time?

Most stacks and tops are made from stainless steel or chrome-plated steel. Stainless steel resists rust and holds up well in most weather conditions, while chrome-plated finishes offer a brighter, mirror-like look but may require more regular cleaning to prevent water spots, road grime, or minor surface oxidation from building up, especially in winter climates where salt is used on roads.

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

Many drivers and owner-operators install stacks and tops themselves using basic tools, since most connections use clamps or slip-fit joints rather than welding. That said, if your setup requires cutting, welding, or modifying existing exhaust brackets, having a qualified shop handle the installation is a safer bet to ensure a secure fit and proper exhaust routing.

Are there any regulations I should be aware of when changing my exhaust stacks or tops?

Exhaust modifications can be subject to state and federal regulations covering noise levels, emissions, and stack height or placement, particularly for commercial trucks. Requirements vary by state and by whether your truck is used for interstate operation, so it is worth checking your local DOT guidelines before making changes to your exhaust system to avoid compliance issues during inspections.
