Peterbilt 352 Elbows, Piping & Comp.

Frequently Asked Questions About Peterbilt 352 Elbows, Piping & Comp.

What size exhaust elbows and pipes fit the Peterbilt 352, and how do I measure for the correct fit?

Most Peterbilt 352 models use 5-inch diameter exhaust systems, though some heavy-duty applications may require 6-inch components. To ensure proper fit, measure the outside diameter (OD) of your existing exhaust pipe at the connection point. Also check the degree of bend needed - common angles are 45, 60, and 90 degrees. For cab-to-stack applications, measure the distance between your exhaust outlet and desired stack location to determine the correct elbow length.

Are these exhaust components made from aluminized or stainless steel, and which material lasts longer?

We carry both aluminized steel and stainless steel options. Aluminized steel components typically last 3-5 years and offer good corrosion resistance at a lower price point. Stainless steel (usually 409 or 304 grade) can last 7-10+ years and handles extreme temperatures better, making it ideal for trucks operating in harsh climates or with high exhaust temperatures. For coastal areas or heavy salt exposure, we strongly recommend stainless steel.

Will these parts fit my specific year Peterbilt 352, and are there differences between model years?

While the Peterbilt 352 maintained consistent exhaust routing through most production years, there are some variations. Pre-1980 models may have different mounting brackets and clearances compared to 1980-1986 models. Always verify your truck's build date and compare mounting points. Most universal elbows and straight pipes will fit, but cab-specific components may require year verification. Contact us with your OEM if you need help confirming compatibility.

What tools and additional parts do I need for installation, and how difficult is it to install myself?

Basic installation requires a reciprocating saw or exhaust pipe cutter, band clamps or U-bolt clamps (usually 5-inch or 6-inch), high-temperature exhaust sealant, and standard hand tools. Most DIY mechanics can complete the job in 2-3 hours. You may also need exhaust hangers or mounting brackets if replacing entire sections. Common challenges include removing rusted connections and ensuring proper alignment to prevent leaks. Having a helper makes positioning easier, especially for longer pipe sections.

Do you offer chrome or polished finishes, and how do they hold up compared to standard finishes?

Yes, we stock chrome-plated and polished stainless options alongside standard aluminized and raw stainless finishes. Chrome elbows provide excellent appearance but require regular cleaning to prevent pitting and discoloration from exhaust heat. Polished stainless maintains its shine better over time and can be re-polished if needed. For working trucks, standard finishes often prove more practical, while show trucks benefit from the aesthetic upgrade of chrome or polished components. Chrome components typically need replacement every 2-3 years in daily use applications.
