Frequently Asked Questions About International LT Exhaust Parts
What are the main differences between aluminized and chrome exhaust stacks for my International LT?
Aluminized steel exhaust parts offer excellent corrosion resistance and heat dissipation at a more affordable price point, typically lasting 5-7 years with proper maintenance. Chrome stacks provide superior aesthetics and durability, often lasting 10+ years, but require regular polishing to maintain their mirror finish. For International LT models operating in harsh weather conditions or heavy salt exposure, chrome is recommended despite the higher initial cost.
Will aftermarket exhaust parts fit my 2017-2024 International LT without modifications?
Most quality aftermarket exhaust components are designed as direct-fit replacements for 2017-2024 International LT models. However, variations can occur based on your specific engine configuration (Cummins X15, International A26, or Navistar N13). Always verify the part number matches your OEM-specific requirements, particularly for DPF and SCR equipped trucks. Pre-2020 models may have different mounting bracket configurations than 2020+ models.
How difficult is it to install a new exhaust stack or muffler on an International LT?
Installation typically takes 2-4 hours for experienced mechanics and requires basic tools including band clamps, exhaust hangers, and potentially a sawzall for removing old components. The most challenging aspect is usually removing corroded factory clamps and aligning new components properly. Professional installation is recommended for DPF-back systems or when dealing with emissions equipment to avoid check engine lights or compliance issues.
What diameter exhaust stack works best for International LT performance and appearance?
The standard 5-inch diameter exhaust is optimal for most International LT applications, providing the best balance of performance, fuel efficiency, and sound. While 6-inch stacks offer a more aggressive appearance and slightly deeper tone, they can create excessive backpressure on stock engines. For modified or high-performance builds exceeding 500 HP, 6-inch may be beneficial. Always ensure your choice maintains proper exhaust gas temperatures and doesn't void emissions compliance.
How do I prevent exhaust stack discoloration and maintain the finish on my International LT?
Chrome stacks require monthly cleaning with specialized chrome polish and should be wiped down weekly to prevent water spots and exhaust residue buildup. Aluminized stacks benefit from high-temperature paint touch-ups annually and should be inspected for rust at mounting points. Installing a rain cap prevents internal corrosion, while heat shields can reduce discoloration near the stack base. Avoid using abrasive cleaners or steel wool, which can damage protective coatings.
