Frequently Asked Questions About International ProStar Chrome Stacks & Tops

What are the material differences between straight chrome and curved chrome stacks for the ProStar?

Our International ProStar chrome stacks are typically available in 304 or 316 stainless steel with mirror-polished chrome finish. Straight stacks offer a classic, traditional look and are generally easier to install, while curved stacks provide better aerodynamics and modern styling. Both materials offer excellent corrosion resistance, but 316 stainless steel provides superior durability in harsh weather conditions and areas with road salt exposure. The wall thickness typically ranges from 16-gauge to 18-gauge depending on the manufacturer.

Will these chrome stacks fit my specific ProStar model year, and what adapters might I need?

Chrome stacks designed for International ProStar models typically fit 2008-2017 model years with standard 5-inch exhaust systems. However, some ProStar models with DPF (Diesel Particulate Filter) systems may require specific bracket adapters or modification to the existing exhaust configuration. We recommend checking your current exhaust outlet diameter and comparing it with the stack inlet size. Most stacks come with reducing clamps to accommodate both 5-inch and 6-inch systems, but always verify your specific model's requirements before ordering.

How difficult is the installation process, and what tools will I need?

Installation typically takes 1-3 hours depending on your experience level and whether you're replacing existing stacks or installing from scratch. You'll need basic hand tools including socket wrenches (typically 9/16" and 5/8"), a torque wrench, and potentially a sawzall if you need to cut existing exhaust pipes. Most installations require loosening the existing exhaust clamps, removing old stacks if present, and securing the new chrome stacks with the provided band clamps. Some installations may require drilling new mounting holes or adjusting bracket positions. We recommend having penetrating oil on hand for stubborn bolts.

What's the difference between bull hauler, miter cut, and turn-out style tops?

Bull hauler tops feature a straight-cut design that directs exhaust straight up, ideal for maximum chrome visibility and traditional styling. Miter cut tops have an angled cut (usually 15-45 degrees) that directs exhaust away from the cab and reduces cab soot buildup. Turn-out tops curve the exhaust outlet 90 degrees to direct exhaust to the side, providing the best protection against rain entry and minimizing soot on your trailer. Your choice depends on your aesthetic preference and practical needs - miter cuts and turn-outs are generally better for everyday driving conditions.

How do I maintain the chrome finish and prevent discoloration from exhaust heat?

Chrome stacks require regular maintenance to maintain their mirror finish. Clean them every 2-4 weeks with a quality chrome polish and microfiber cloth, paying special attention to the area near the exhaust outlet where heat discoloration is most common. For stubborn exhaust stains, use a specialized chrome cleaner or fine steel wool (0000 grade only). Apply a heat-resistant chrome sealant every 3-6 months to protect against bluing and discoloration. Avoid using abrasive cleaners or rough materials that can scratch the chrome surface. Internal heat shields, available separately, can help reduce heat damage to the chrome finish.
