Frequently Asked Questions About Freightliner FLC112 Elbows, Piping & Comp.

What years and models are these exhaust elbows and pipes compatible with?

Our FLC112 exhaust components are designed to fit Freightliner FLC112 models from 1984 through 2003. These parts are specifically engineered for the FLC112 series, including both day cab and sleeper configurations. Always verify your truck's exact model year and engine configuration before ordering, as some variations may require different pipe lengths or elbow angles depending on whether you have a Caterpillar, Cummins, or Detroit engine.

Are these exhaust elbows made from aluminized or stainless steel, and which should I choose?

We offer both aluminized steel and stainless steel options. Aluminized steel elbows typically last 3-5 years under normal conditions and provide good corrosion resistance at a lower price point. Stainless steel components, while more expensive initially, can last 10+ years and maintain their appearance better in harsh weather conditions. If you operate in areas with heavy road salt or extreme weather, stainless steel is worth the investment. For moderate climates and standard highway use, aluminized steel offers excellent value.

What tools and additional parts do I need for installation?

Installation typically requires basic hand tools including socket wrenches (usually 9/16" and 5/8"), a pipe cutter or sawzall for any necessary adjustments, and exhaust clamps (if not included). You'll also need exhaust sealant rated for high temperatures. Many installations require new gaskets, which should be replaced during any exhaust work. Budget 2-4 hours for installation depending on your experience level. Some tight clearances may require removing heat shields or other components for access.

What's the difference between straight pipes, curved elbows, and flex pipes for my FLC112?

Straight pipes provide direct exhaust flow and are ideal for simple stack configurations. Curved elbows (available in 45, 60, and 90-degree angles) help route exhaust around frame rails and other components. Flex pipes are essential for absorbing engine movement and vibration - without them, rigid pipes can crack at stress points. Most FLC112 setups require a combination of these components. A typical configuration includes a flex pipe off the turbo, followed by straight sections and elbows to reach your desired exit point.

How do I determine the correct pipe diameter and length for my setup?

Most FLC112 trucks use either 4-inch or 5-inch diameter exhaust systems, with 5-inch being more common on higher horsepower engines. Measure your existing system at the turbo outlet to confirm. For length, measure from your connection point to where you want the exhaust to exit, accounting for any bends needed. It's better to order slightly longer pipes that can be trimmed than to come up short. If converting from a horizontal to vertical stack setup, add approximately 18-24 inches to account for the upward turn.
