International PayStar 5000 Chrome Stacks & Tops

Frequently Asked Questions About International PayStar 5000 Chrome Stacks & Tops

What exactly are exhaust stacks and stack tops used for on the International PayStar 5000?

Exhaust stacks are the vertical pipes that route exhaust away from the engine and up above the cab, while stack tops (also called rain caps or stack caps) attach to the top of the stack to keep rain, snow, and debris from entering the exhaust system when the truck is parked or idling. On the PayStar 5000, chrome stacks and tops are a popular way to both handle exhaust routing and add a polished, finished look to the truck.

Will these chrome stacks and tops fit my specific PayStar 5000 without modification?

Fit depends on your truck's existing exhaust diameter, stack length, and mounting configuration, since PayStar 5000s can be spec'd with different exhaust setups depending on year and options. Always check the listed diameter (commonly 5 inch or 6 inch) and length against your current stack before ordering, and reach out to our team if you're unsure so we can help confirm compatibility before you buy.

What's the difference between chrome-plated and stainless steel stacks, and which holds up better?

Chrome-plated stacks typically start as steel or aluminized steel with a chrome finish applied over top, giving a bright, mirror-like shine at a lower cost. Stainless steel stacks cost more upfront but generally resist corrosion and pitting better over time, especially in areas with road salt or heavy weather exposure. Both finishes will need regular cleaning to keep their shine, but stainless tends to be more forgiving if maintenance is inconsistent.

How do I install a new stack top, and do I need any special tools?

Most stack tops are designed to slide or clamp onto the existing exhaust stack, often secured with set screws or a simple friction fit, so basic hand tools like a wrench or screwdriver are usually all that's needed. Before installing, make sure the stack diameter matches the top exactly and that the stack is cool and clean for a secure fit. If your setup uses a swivel or flip-style top, double check that it moves freely and seats properly once mounted.

How do I keep chrome stacks looking good and prevent rust or discoloration?

Regular washing with a mild soap and water solution helps remove road grime, bugs, and exhaust soot before they bake onto the chrome finish. A dedicated chrome polish applied periodically will help maintain shine and add a layer of protection against moisture. Since these stacks sit right at the exhaust outlet, some heat discoloration near the top is normal over time and is generally cosmetic rather than a sign of a problem.
