Western Star 5700XE Truck Chrome Stacks & Tops

Frequently Asked Questions About Western Star 5700XE Truck Chrome Stacks & Tops

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

Chrome stacks refer to the exhaust pipe sections that run up the back or side of the cab, while stack tops (also called exhaust tips or rain caps) are the decorative and functional caps that fit onto the top of those exhaust pipes. Stack tops help direct exhaust flow away from the cab, can reduce water intrusion when curved or angled designs are used, and give the exhaust system a finished, custom appearance.

Will these stacks and tops fit my Western Star 5700XE exhaust system?

Fitment depends on the diameter of your existing exhaust pipe and the specific exhaust configuration on your 5700XE. Most stacks and tops are sold by pipe diameter (commonly 5 inch, 6 inch, or 7 inch), so it is important to measure your current exhaust pipe before ordering. If you are unsure of your truck's exhaust size or configuration, our team can help you confirm the correct fit before you buy.

What material and finish options are available, and how do they hold up over time?

These stacks and tops are typically available in stainless steel or chrome-plated stainless steel. Stainless steel offers strong corrosion resistance and is a common choice for daily drivers, while chrome-plated finishes provide a brighter, mirror-like shine that many owners prefer for show trucks. Regular washing helps maintain the finish and prevent heat discoloration or road grime buildup over time.

How difficult is it to install a new stack or top, and do I need a shop to do it?

Many stack tops are designed as a slip-fit or clamp-on installation over the existing exhaust pipe, which can often be done with basic hand tools. Full stack replacements that involve the exhaust pipe itself may require more work, including proper alignment and mounting bracket adjustments. If your installation involves cutting, welding, or modifying existing exhaust components, we recommend having a qualified diesel shop complete the work.

Are chrome stacks and tops legal to install on my truck?

In most cases, aftermarket exhaust stacks and tops are legal as long as they do not alter emissions equipment or exhaust routing in a way that violates state or federal regulations. However, rules can vary by state, so it is a good idea to check your local regulations, particularly if your modification changes exhaust height, angle, or emissions system components.
