Adding your products to cart

The International WorkStar Elbows, Piping & Components category offers a variety of high-quality exhaust solutions for semi-trucks. This includes durable aluminized steel and stainless steel pipes, elbows, flexible tubing, and connectors. Designed for a custom fit, these components enhance both performance and appearance. All products are built to last from 90-degree elbows to Y-pipes and straight pipes. Whether replacing old parts or upgrading your exhaust system, this category has the right components.

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

What part of the truck do these elbows and piping components come from?

This category covers exhaust and charge air system components for the International WorkStar, including exhaust elbows, connecting pipes, and related fittings that route exhaust or turbocharger air between the engine, turbo, and exhaust stack. These parts are used to replace worn, cracked, or rusted-out sections of the original piping.

Will these parts fit my specific WorkStar model year and engine?

International WorkStar trucks span multiple model years and engine configurations, so pipe diameter, bend angle, and mounting points can vary. Always check the listed part number, diameter, and engine application against your truck's existing component before ordering, and compare against your OEM part number when possible to confirm an exact match.

What material are these elbows and pipes made from, and will they hold up to heat and road conditions?

Exhaust and piping components in this category are typically constructed from steel or aluminized steel to withstand high exhaust temperatures and outdoor exposure. Aluminized finishes generally offer better resistance to rust and scaling than plain steel, but all exhaust components will show wear over time from heat cycling and road debris.

Can I install these myself, or do I need a shop to do it?

Many elbows and straight pipe sections can be swapped with basic hand tools if you're comfortable working underneath the truck, especially when replacing a like-for-like section. However, jobs involving welded joints, tight clearances near the turbo, or components integrated with emissions equipment are often better handled by a shop with the right lift and cutting tools.

Do these components affect emissions compliance?

Some piping sections connect directly to emissions-related components such as the turbocharger, DPF, or EGR system. If a part is positioned before or within the emissions system, replacing it with anything other than an equivalent, correctly fitting piece could affect emissions performance. When in doubt, match the original part specifications closely or consult your service manual before making changes.
