Peterbilt 352 Exhaust Parts

Frequently Asked Questions About Peterbilt 352 Exhaust Parts

Will these exhaust parts fit my specific year Peterbilt 352?

Most of our Peterbilt 352 exhaust components are designed to fit models from 1969 through 1981, which covers the entire production run. However, there were minor variations between early models (1969-1975) and later models (1976-1981), particularly in mounting bracket positions and pipe diameter specifications. We recommend checking your existing exhaust system measurements or contacting our support team with your OEM to ensure proper fitment. Stack kits and mufflers are generally universal across all 352 model years, but Y-pipes and elbows may require year-specific selection.

What's the difference between aluminized and chrome exhaust stacks, and which should I choose?

Aluminized steel stacks offer excellent corrosion resistance at a lower price point and are ideal for working trucks that see regular use in harsh conditions. They maintain a subtle, professional appearance and typically last 5-7 years. Chrome stacks provide a mirror finish for show trucks and last 10+ years with proper care, but require regular polishing to maintain their appearance. Chrome is more susceptible to pitting from road salt and requires immediate cleaning after exposure. For daily drivers, we typically recommend aluminized, while chrome is preferred for show trucks or owner-operators who prioritize appearance.

Do I need special tools or professional installation for these exhaust parts?

Most Peterbilt 352 exhaust components can be installed with standard hand tools including socket sets, wrenches, and a reciprocating saw for removing old parts. Stack installation typically requires 2-3 hours and basic mechanical skills. The most challenging aspect is usually removing corroded factory clamps and hangers. We recommend having penetrating oil, new grade 8 mounting hardware, and high-temperature exhaust sealant on hand. Professional installation is advisable for complete system overhauls or if you're uncomfortable working under the truck. Many customers successfully complete installations in their driveways with jack stands or ramps.

What size exhaust pipes and stacks work best with the Peterbilt 352?

The Peterbilt 352 originally came with 5-inch exhaust systems, and this remains the most popular size for replacement parts. We offer 5-inch, 6-inch, 7-inch, and 8-inch options, with 5-inch providing optimal back pressure for most engine configurations. Upgrading to 6-inch or larger is beneficial for heavily modified engines producing over 500 horsepower. Stack heights typically range from 48 to 96 inches, with 60-72 inches being most common for highway use. Consider your state's height restrictions and garage clearance when selecting stack length. Curved stacks should match your cab configuration - standard or extended.

How do I prevent exhaust leaks at connection points?

Exhaust leaks commonly occur at Y-pipe connections, muffler joints, and stack bases due to thermal expansion and vibration. Use high-quality band clamps rated for diesel exhaust temperatures (1000?F+) rather than standard U-bolt clamps. Apply a thin layer of high-temp exhaust sealant at all slip-joint connections before assembly. Ensure all mounting brackets are secure and use rubber isolators to reduce vibration transfer. Check and retighten all connections after the first 500 miles of operation when components have gone through several heat cycles. Regular inspection every 6 months helps catch developing leaks early.
