Kenworth T700 Elbows, Piping & Comp.

Frequently Asked Questions About Kenworth T700 Elbows, Piping & Comp.

What is included in this category?

This category covers exhaust and air intake system components for the Kenworth T700, including exhaust elbows, piping sections, couplers, clamps, and related connecting components. These parts are used to route exhaust gases from the engine or turbo through the aftertreatment system and out through the stack, as well as to connect intake ducting between the air filter housing and the turbocharger.

How do I know if a piping or elbow component will fit my Kenworth T700?

Fitment depends on the diameter, angle, length, and material of the piece, as well as where it sits in the exhaust or intake system, such as pre-turbo, post-turbo, or aftertreatment connections. Always compare the part number and dimensions against your truck's original component, and check the model year and engine configuration, since specifications can change across production runs. If you are unsure, our team can help confirm the correct part before you order.

What materials are these elbows and piping made from, and does it matter?

Exhaust components are typically made from aluminized steel or stainless steel. Stainless steel generally offers better resistance to corrosion and heat over time, while aluminized steel is a common factory-style option that costs less upfront. Intake piping is often constructed from steel, aluminum, or reinforced rubber couplers depending on its location in the system. The right material choice depends on your budget, climate, and how long you want the part to last.

Can I install these parts myself, or should I have a mechanic do it?

Many piping and elbow components can be installed with basic hand tools, especially if you are replacing a damaged section with a direct-fit part. However, exhaust work often involves clamps, gaskets, and sometimes welding or cutting to achieve a proper seal, so if you are not comfortable with that level of work, it is worth having a qualified diesel technician handle the installation. A poor seal on exhaust or intake components can lead to leaks, reduced performance, or check engine lights.

Will replacing exhaust piping or elbows affect emissions compliance?

Exhaust components that are part of the aftertreatment system, such as piping connected to the DPF or SCR system, need to maintain proper fitment and sealing to keep the emissions system functioning correctly. Using parts that do not match OEM specifications or that create leaks can trigger fault codes or cause the truck to fail an emissions inspection. When in doubt, choose replacement parts designed to match the original configuration for your specific T700 model and engine.
