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

What material are these exhaust elbows made from, and how long do they typically last?

Most International HX exhaust elbows are manufactured from either aluminized steel or 304/409 stainless steel. Aluminized steel elbows typically last 3-5 years under normal driving conditions, while stainless steel options can last 7-10 years or longer. The lifespan depends on factors like climate, road salt exposure, and driving frequency. For maximum durability in harsh conditions, we recommend 304 stainless steel components.

Will these parts fit my specific International HX model year?

International HX exhaust components are generally compatible with models from 2017 to present, but there are important variations. The 2017-2019 models use 5-inch diameter piping, while 2020 and newer models may have different configurations depending on engine type (Cummins X15 or International A26). Always check the product specifications for your exact year and engine combination, or contact our support team with your VIN for verification.

Can I install these exhaust components myself, or do I need professional help?

While experienced mechanics can install these components with basic tools, we recommend professional installation for most customers. The installation typically requires cutting and fitting pipes, proper alignment to prevent leaks, and torquing clamps to specification (usually 40-45 ft-lbs). Common challenges include accessing tight spaces near the DPF system and ensuring proper hangar alignment. Budget 2-4 hours for a complete elbow replacement.

What's the difference between OEM and aftermarket elbows for my International HX?

OEM elbows are exact factory replacements with guaranteed fit but typically cost 40-60% more than quality aftermarket options. Aftermarket elbows from reputable manufacturers offer comparable performance and often feature improvements like thicker walls or better corrosion resistance. Key differences to consider: OEM parts maintain warranty compliance, while aftermarket options may offer better value and enhanced features like polished finishes or mandrel bends for improved flow.

Do these exhaust components affect my truck's emissions compliance or warranty?

Properly designed replacement elbows and pipes that maintain factory specifications will not affect emissions compliance or void your warranty. However, any modifications that alter exhaust flow characteristics, remove emissions components, or change pipe diameter from OEM specifications could impact compliance. All components sold in this category are designed as direct OEM replacements and maintain EPA compliance when installed correctly. Always verify that replacement parts match your original system's specifications.
