Adding your products to cart

Upgrade your truck's performance and style with the International LoneStar Exhaust product lineup. This selection includes various high-quality components such as chrome stacks, DPF, mufflers, elbows, piping, and clamps. Whether you're looking to enhance the sound, appearance, or efficiency of your LoneStar, you'll find the right parts here. With durable and reliable options, this product lineup has everything you need to customize and optimize your truck's exhaust system.

Frequently Asked Questions About International LoneStar Exhaust Parts

What exhaust stack sizes are compatible with my International LoneStar, and will I need adapters?

International LoneStar trucks typically accept 5-inch or 6-inch exhaust stacks, depending on your engine configuration and model year. Most 2008-2020 LoneStar models with ISX or X15 engines use 5-inch DPF systems, while some specialty configurations may have 6-inch outlets. We recommend measuring your current exhaust outlet diameter before ordering. If you're switching sizes, reducer or expander adapters are available, though they may slightly affect exhaust flow and sound.

How difficult is it to install aftermarket exhaust stacks on a LoneStar, and what tools do I need?

Installation typically takes 2-4 hours for experienced mechanics and requires basic hand tools including socket sets, band clamp tools, and potentially a sawzall for trimming. The main challenges involve properly aligning the stacks with existing brackets and ensuring adequate clearance from the cab and sleeper. Many customers report that having a second person helps significantly with positioning. Pre-2015 models may require additional bracket modifications due to changes in the exhaust routing.

Will chrome or stainless steel exhaust parts discolor or rust on my LoneStar?

Chrome-plated stacks will eventually show heat discoloration (blueing) near the base after 6-12 months of use, which is normal. 304 stainless steel resists discoloration better but may develop a golden tint over time. For maximum longevity in harsh climates or heavy-duty applications, we recommend 409 stainless steel, though it has a more industrial appearance. Regular cleaning with appropriate metal polishes can minimize discoloration on both materials.

Are there specific exhaust configurations for LoneStar models with DEF systems?

Yes, 2011 and newer LoneStar models with DEF systems require exhaust components rated for higher temperatures due to the DPF regeneration process. Standard chrome stacks may experience accelerated deterioration near the DPF outlet. Look for exhaust parts specifically marked as "DPF compatible" or rated for 1000?F+ continuous operation. Some aftermarket options include heat shields or thermal wraps to protect chrome finishes.

What's the difference between curved, straight, and miter-cut exhaust stacks for appearance and performance?

Curved stacks direct exhaust away from the trailer and reduce cab soot buildup but can create slightly more back pressure. Straight stacks offer the best flow characteristics and classic appearance but may deposit more soot on your trailer. Miter-cut tops (typically 15-30 degree angles) provide a good compromise, directing exhaust at an angle while maintaining good flow. Turn-out tops are popular for reducing trailer soot but add 2-3 inches to overall height, which matters for garage clearances.
