International IH Cabover Exhaust Parts

Frequently Asked Questions About International IH Cabover Exhaust Parts

Will these exhaust parts fit my specific International Cabover model and year?

Our International IH Cabover exhaust parts are designed to fit most models from the 1960s through the 1990s, including the CO Loadstar, Transtar, and Cargostar series. However, exact fitment can vary based on your truck's original configuration and any modifications. We recommend checking your existing exhaust measurements or contacting our support team with your OEM for confirmation. Stack diameters typically range from 5" to 7", with the most common being 6" for these models.

What's the difference between chrome and stainless steel exhaust stacks?

Chrome-plated stacks offer a brilliant mirror finish at a lower initial cost but require regular polishing and may eventually show pitting or rust, especially in harsh weather conditions. Stainless steel stacks (typically 304 or 316 grade) maintain their appearance longer with less maintenance and resist corrosion better, though they cost more upfront. For trucks exposed to road salt or coastal environments, stainless steel is strongly recommended despite the higher price point.

Do I need special tools or modifications to install these exhaust parts?

Most installations require basic hand tools, including wrenches, sockets, and possibly a reciprocating saw for removing old components. Stack installations typically use band clamps or flanged connections. Some older Cabovers may require adapter plates when upgrading from original equipment to modern aftermarket parts. Installation usually takes 2-4 hours depending on whether you're replacing just the stacks or the entire system including elbows and rain caps.

What exhaust stack height should I choose for my Cabover?

Stack height depends on your specific application and local regulations. Most International Cabovers originally came with 48" to 60" stacks, but many drivers prefer 72" to 96" for better smoke dispersal and appearance. Consider your garage door clearance, low bridges on regular routes, and state height restrictions (typically 13'6" to 14' total vehicle height). Remember that longer stacks may require additional bracing to prevent excessive vibration.

Are these exhaust parts direct replacements or will I need additional components?

While many of our exhaust stacks and pipes are designed as direct replacements, International Cabovers went through several design changes over the years. You may need additional components such as reducers, elbows, or mounting brackets depending on your specific model. Most complete installations require stacks, elbows, clamps, and rain caps. We offer complete kits for common configurations, or you can purchase components individually to match your existing setup.
