Western Star Heritage Truck Chrome Stacks & Tops

Frequently Asked Questions About Western Star Heritage Truck Chrome Stacks & Tops

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

Chrome stacks are the exhaust pipes that run vertically along the back or side of the cab on your Western Star Heritage truck, while the tops (also called stack caps or rain caps) fit onto the end of the stack to keep moisture and debris out of the exhaust system when the engine is off. Together they handle exhaust routing and add a finished, classic look to the truck.

Will these stacks and tops fit my specific Western Star Heritage model?

Stack diameter and length can vary between model years and configurations, so it is important to measure your existing stack's outer diameter and overall length before ordering, or check the listed specs against your truck's OEM setup. If you are unsure, reach out to our team with your truck's year and configuration and we can help confirm the right fit.

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

Most chrome stacks and tops are made from stainless steel or aluminized steel with a chrome-plated finish for that classic bright look. Chrome finishes resist rust and corrosion well but still require regular washing to prevent road grime and exhaust soot from dulling the shine over time.

How difficult is it to install new stacks and tops myself?

Installation typically involves removing the old stack sections and clamps, then fitting the new pipe and securing it with the appropriate exhaust clamps before attaching the top. Many truck owners handle this in their own shop with basic tools, but if your exhaust routing includes bends, heat shields, or brackets specific to your cab setup, having a diesel technician assist can help ensure a secure, leak-free fit.

Are there any regulations I should be aware of when replacing exhaust stacks?

Exhaust stack height, placement, and emissions routing can be subject to state and federal regulations, particularly regarding smoke opacity and clearance from cab structures. Before making changes to your stack configuration, it is a good idea to check your local DOT requirements to make sure your setup stays compliant.
