Frequently Asked Questions About Kenworth T660 Elbows, Piping & Comp.

What kinds of parts are included in this category?

This category covers the exhaust system components for the Kenworth T660, including exhaust elbows, piping sections, and related fittings that connect the muffler, stacks, and aftertreatment components. These parts are used to route and support exhaust flow from the engine or turbo up through the stack assembly.

How do I know if a piping or elbow component will fit my T660?

Fit depends on the diameter, angle, and length of the elbow or pipe section, as well as the specific exhaust configuration on your truck, such as single or dual stacks and engine setup. Always compare the measurements and part specifications listed on the product page to the components currently on your truck, or check with our parts team if you are unsure before ordering.

What materials are these elbows and pipes made from, and how do they hold up?

Exhaust elbows and piping are typically made from aluminized or stainless steel to withstand high exhaust temperatures and resist corrosion over time. Stainless steel options generally offer better long-term rust resistance, while aluminized steel provides a more budget-friendly choice for standard use.

Can I install these parts myself, or do I need a professional?

Many drivers and shop technicians are able to replace elbows and straight piping sections with basic tools, especially when the new part matches the original diameter and clamp style. However, if the installation involves cutting, welding, or working near turbo or aftertreatment connections, it is best handled by a qualified diesel technician to ensure a proper seal and fit.

Will replacing an exhaust elbow or pipe affect emissions compliance?

Components installed ahead of the DPF, DOC, or other aftertreatment devices can affect emissions performance if they alter exhaust flow or introduce leaks. To stay compliant, use replacement parts that match the original dimensions and routing, and avoid modifying factory aftertreatment configurations.
