Frequently Asked Questions About International RH Elbows, Piping & Comp.

Will these RH elbows fit my specific International truck model and year?

Most of our RH elbows are designed to fit International ProStar, LoneStar, and 9900i models from 2008 onwards. However, exact fitment can vary based on your engine configuration and existing exhaust setup. We recommend checking the product specifications for each item or contacting our support team with your VIN number to ensure proper compatibility. Pay special attention to inlet/outlet diameters and mounting bracket positions.

What's the difference between aluminized and chrome elbows, and which should I choose?

Aluminized steel elbows offer excellent corrosion resistance and heat dissipation at a lower price point, making them ideal for work trucks and budget-conscious buyers. Chrome elbows provide a mirror-like finish for show trucks but require more maintenance to prevent pitting and discoloration. For daily drivers in harsh weather conditions, aluminized typically lasts longer with less upkeep. Chrome is best for trucks that are garaged and regularly cleaned.

Do I need special tools or professional installation for these exhaust components?

Basic installation typically requires standard hand tools including wrenches, sockets, and potentially a sawzall for modifications. Most experienced DIY mechanics can complete the installation in 2-4 hours. However, you may need exhaust clamps, hangers, or adapters depending on your current setup. Professional installation is recommended if you need to modify existing piping or if your truck has aftermarket modifications that could affect fitment.

What pipe diameter do I need for my International truck?

Most International trucks use 5-inch diameter exhaust systems, but some models may have 4-inch or 6-inch setups depending on engine size and configuration. Check your existing exhaust pipe diameter before ordering. If upgrading from a smaller diameter, ensure your entire system can accommodate the change without creating restrictions. Measure the outside diameter of your current pipe for accurate sizing.

How do these aftermarket elbows compare to OEM parts in terms of quality and longevity?

Our aftermarket RH elbows are manufactured to meet or exceed OEM specifications, often using heavier gauge materials than factory parts. Many customers report 5-7 years of service life with aluminized options and 3-5 years with chrome in typical conditions. The main advantages over OEM include lower cost, better availability, and often improved construction. Look for options with reinforced seams and proper heat shielding for maximum durability.
