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

What material are these elbows and pipes made from, and will they rust or corrode over time?

Most International LoneStar exhaust elbows and pipes are manufactured from either aluminized steel or 304/409 stainless steel. Aluminized steel options provide good corrosion resistance at a lower price point and typically last 3-5 years depending on your climate and road conditions. Stainless steel components offer superior longevity, often lasting 7-10 years or more, making them ideal for trucks operating in harsh weather conditions or areas with heavy road salt usage. Always check the product description for specific material specifications.

Will these parts fit my specific International LoneStar model year, and are there different configurations I need to know about?

International LoneStar exhaust components are typically designed to fit model years 2008-2021, but fitment can vary based on your specific engine configuration (Cummins ISX, MaxxForce, etc.) and exhaust setup. Key factors include whether you have a single or dual exhaust system, DPF/DEF equipped models, and cab configuration. We recommend checking your existing pipe diameter (usually 5" or 6") and comparing OEM part numbers when possible. If you're unsure, contact our support team with your VIN for exact fitment verification.

How difficult is the installation process, and what tools or additional parts will I need?

Installation difficulty ranges from moderate to challenging depending on which components you're replacing. Basic elbow replacements typically take 1-2 hours and require standard hand tools, exhaust clamps, and potentially a reciprocating saw for removing old components. Complete system overhauls may require 4-6 hours and additional items like hangers, gaskets, and band clamps. Many customers report that having a lift or working over a pit makes the job significantly easier. Anti-seize compound on all connections is highly recommended for future serviceability.

What's the difference between OEM and aftermarket options in terms of quality and performance?

OEM International parts guarantee exact fit and finish but come at a premium price. Quality aftermarket options from established manufacturers often provide 90-95% of OEM performance at 40-60% of the cost. Key differences include wall thickness (aftermarket may be slightly thinner), bend radius precision, and warranty coverage. For most applications, premium aftermarket parts offer excellent value without sacrificing reliability. Look for brands that specifically state they meet or exceed OEM specifications.

Are these parts emissions compliant, and will they affect my truck's warranty or inspection status?

All exhaust components sold for highway use must meet EPA regulations. Stock replacement parts that maintain factory emissions equipment (DPF, DEF, catalytic converters) are fully compliant and won't affect warranties or inspections. Any modifications that alter or remove emissions components may void warranties and cause inspection failures. For trucks operating in California, ensure parts are CARB compliant. When in doubt, choose direct OEM replacement parts that maintain all factory emissions systems intact.
