Frequently Asked Questions About International 9900/i/ix Exhaust Parts

What years and models are compatible with these exhaust parts?

Our International 9900/i/ix exhaust parts are designed to fit International 9900i models from 1999-2004 and 9900ix models from 2005-2016. The 9900i and 9900ix have different exhaust configurations, so double-check your truck's model year before ordering. Most parts specify whether they fit pre-2005 (9900i) or post-2005 (9900ix) models. If you're unsure about compatibility, check your OEM or contact us with your truck's specific year and engine type.

What's the difference between aluminized and chrome exhaust stacks?

Aluminized steel stacks offer good corrosion resistance at a lower price point and typically last 3-5 years with regular maintenance. Chrome stacks provide superior shine and durability, lasting 7-10 years or more, but cost significantly more. Aluminized stacks can develop a matte finish over time, while chrome maintains its mirror-like appearance with proper care. For trucks in harsh winter climates with heavy road salt exposure, chrome is worth the investment.

Do I need special tools or brackets for installation?

Most exhaust stack installations require basic hand tools, but you'll need proper clamps and mounting brackets specific to your truck's configuration. International 9900 series trucks typically use 5-inch exhaust systems, requiring matching clamps and reducers if transitioning from different pipe sizes. Stack installation usually takes 2-3 hours. For DPF-equipped 2007+ models, ensure any modifications comply with emissions regulations. We recommend haOEMg exhaust sealant and new gaskets on hand.

What exhaust tip styles work best for International 9900 trucks?

The most popular styles for International 9900 series are curved stacks (for that classic look), straight pipes with turnout tips, and miter-cut stacks. West Coast-style curved stacks typically measure 96-108 inches for proper clearance above the cab. Bull hauler stacks work well for flatbed applications. Consider your trailer type - dump truck operators often prefer straight stacks to avoid clearance issues when tipping. Factory locations accommodate dual 5-inch or single 6-inch configurations.

How do I prevent exhaust stacks from discoloring or rusting?

Regular cleaning every 2-4 weeks prevents buildup that causes discoloration. Use specialized exhaust cleaners or mild soap - avoid harsh chemicals that damage chrome or aluminized coatings. Apply high-temperature wax or polish after cleaning chrome stacks. For aluminized stacks, high-temp paint can restore appearance. Internal rust prevention requires ensuring proper drainage - drill weep holes if needed. During winter months, rinse salt residue weekly. Heat shields can prevent cab discoloration from exhaust heat.
