Adding your products to cart

Upgrade your truck's exhaust system with the International S1700-S1900 Elbows, Piping & Comp. category. This selection includes essential components like elbows, Y-pipes, adapters, and piping solutions designed for durability and reliable performance. With aluminized and stainless steel construction, these parts resist corrosion and offer long-lasting use. Whether replacing components or improving airflow, this assortment of high-quality solutions allows for smooth and efficient operation.

Frequently Asked Questions About International S1700-S1900 Elbows, Piping & Comp.

What kinds of parts are included in this category?

This category covers exhaust and intake system elbows, piping sections, and related components designed for International S1700 and S1900 series trucks. This includes items such as exhaust elbows, turbo piping, intake elbows, and connecting pipe sections used throughout the engine's air and exhaust routing system.

Will these elbows and piping fit my specific International S1700 or S1900 truck?

Fitment can vary depending on the engine configuration, model year, and cab style of your specific truck. We recommend checking the listed specifications on each product page and comparing part numbers or dimensions to your existing components before ordering. If you are unsure, contacting our parts team with your VIN or engine details will help confirm the correct fit.

What materials are these components made from, and how durable are they?

Most elbows and piping in this category are constructed from steel or aluminized steel to withstand exhaust heat and road vibration. Some pieces may include a chrome or painted finish depending on their application. Material and finish details are listed on each individual product page, so be sure to review those specifics before purchasing.

Are these parts OEM or aftermarket, and does that affect installation?

We carry both OEM and quality aftermarket options in this category. OEM parts are built to match original factory specifications, which typically means a more straightforward installation using existing mounting points and hardware. Aftermarket pipes and elbows are generally designed to be a direct-fit replacement as well, but minor adjustments or additional clamps may occasionally be needed. Product descriptions will note whether an item is OEM or aftermarket.

Do I need any special tools or professional help to install these components?

Basic elbow and piping replacements can often be handled with standard hand tools, such as wrenches and pliers for clamps and mounting brackets. However, because these parts are part of the exhaust or intake system, proper sealing and alignment are important to avoid leaks or performance issues. If you are not experienced with exhaust or intake work, having a qualified technician handle the installation is a good way to ensure everything is fitted correctly and safely.
