Frequently Asked Questions About Peterbilt 362 Elbows, Piping & Comp.

Will these exhaust elbows and pipes fit my specific year Peterbilt 362?

Most exhaust elbows and piping for the Peterbilt 362 are compatible across all model years (1980-1986), as the exhaust routing and frame dimensions remained consistent throughout production. However, always verify the inlet/outlet diameter sizes before ordering. Standard sizes are typically 5-inch for most 362 models, but some configurations may use 4-inch or 6-inch components depending on engine specifications and aftermarket modifications.

What's the difference between aluminized steel and chrome exhaust components?

Aluminized steel pipes offer good corrosion resistance at a lower price point and typically last 3-5 years in normal conditions. Chrome-plated steel provides superior appearance and durability, lasting 5-10 years with proper care, but costs significantly more. For trucks in northern climates with road salt exposure, we recommend chrome or 304 stainless steel options. Aluminized works well for mild climates or trucks that see limited road time.

Do I need special tools or professional installation for exhaust elbows and pipes?

Basic exhaust component replacement can be done with standard hand tools including wrenches, a reciprocating saw for removing old pipes, and exhaust clamps. However, proper alignment is crucial to prevent stress cracks and leaks. We recommend having exhaust hangers, high-temperature sealant, and new clamps on hand. Professional installation typically takes 2-3 hours and may be worth considering if you're replacing multiple sections or dealing with rusted, seized connections.

How do I know what degree elbow I need for my Peterbilt 362?

The most common elbow angles for the 362 are 45-degree and 90-degree bends. To determine what you need, trace your current exhaust routing or measure the angle where your exhaust needs to turn. Standard cab 362s typically use a 90-degree elbow exiting the turbo, while extended cab models may require different configurations. When in doubt, order adjustable angle elbows or contact us with photos of your current setup for guidance.

Why are my new exhaust pipes turning blue or discoloring?

Blue or gold discoloration on exhaust pipes is normal and indicates high heat exposure, especially near the turbo outlet and first few feet of piping. This doesn't affect performance or durability. Chrome pipes may show this more prominently than aluminized steel. To minimize visible discoloration, ensure your engine isn't running excessively hot, check for exhaust restrictions, and consider heat wrap for the first 2-3 feet of piping after the turbo if appearance is a primary concern.
