Peterbilt 389 Exhaust Systems & Chrome Stacks

Repair and restore the entire Peterbilt 389 exhaust system with a comprehensive selection of exhaust pipes, stacks, and hardware. Shop for premier aftermarket exhaust kits from brands like Lincoln Chrome, made to fit Peterbilt 389 model years (2011-2017 and 2018– 2023). Add clamps, Y-pipe hanger brackets, bushing kits, elbows, bellows kits, and more.

Aftermarket Peterbilt 389 Exhaust Upgrades

Find the hardware you need to keep your exhaust system sealed, stable, and functioning at a high level. Avoid costly exhaust installation mistakes by being prepared with the right hardware for a one-and-done DIY-exhaust installation. Metal Flex Pipe: stabilize the exhaust as it moves in tandem the Peterbilt 389 cab ride suspension. Pre-Formed Stainless Band Clamps: To create a leak-free seal without crushing the tubing. Polyurethane or Heavy-Duty Rubber Exhaust Bushings: To isolate engine vibration and prevent rattling. High-Temp Gaskets: Essential at every flange and manifold connection to stop minor exhaust leaks before they erode clamps or trigger backpressure sensors.

Replacement DPFs, Mufflers & Emissions Components

Reduce backpressure, promote stronger engine performance, and lower EGTs with our in-stock selection of high-flow semi truck mufflers, DPF/DOC 1-box assemblies, and other heavy-duty emissions system parts.

How to Choose the Right Exhaust Setup for Your 389

For newer 389 models, chrome stack kits require a DPF shift kit or specialized long-drop elbows to properly reroute exhaust from the factory-style under-step emissions canister. Verify if the Peterbilt 389 chrome exhaust kit is made for EPA10, GHG14, or newer emissions architecture. Choose a stack diameter and sound profile. The smaller exhaust diameter creates a lighter popping sound while the wider stacks have a deeper, rumbling tone.
  • 5-Inch Stacks (The Practical Standard): Provides a clean, factory-balanced look and modest exhaust flow improvement without overwhelming cab acoustics.
  • 6-Inch to 7-Inch Stacks (The Owner-Operator Sweet Spot): Delivers a deeper, more resonant tone and a bolder visual presence. This is the most popular range for custom highway trucks.
  • 8-Inch to 10-Inch Stacks (The Show Rig Tier): Massive and loud, these require heavy-duty bracket support and reinforced mounting plates to prevent vibration stress cracks on the body. They are ideal for extreme custom builds where aesthetics are paramount.
Choose the right chrome stack top style for your Peterbilt 389 theme:
  • Miter Cut: Angled, sharp, and traditional; the most popular choice for custom 389s.
  • Flat Top: A clean, classic straight-pipe look.
  • Turn-Out / Curved: Directs exhaust gases away from the trailer or sleeper, useful for specific vocational applications.
  • Bullhorn: Flared outward for a distinct, aggressive acoustic resonance.
Choose the right material: Aluminized Steel: The budget-friendly choice (lasting 3–5 years). Best for dry, southern climates or fleets prioritizing lower upfront costs, though prone to surface rust in northern winter salt. Triple Chrome-Plated Steel: The classic custom choice. Delivers a brilliant mirror finish for show trucks, but requires regular polishing and maintenance to prevent chrome pitting from intense heat cycles. 304 Stainless Steel: The longevity champion (7–10+ years). Ideal for long-hauls during winter weather due to its high corrosion resistance and less upkeep requirements.

Frequently Asked Questions About Peterbilt 389 Exhaust Parts

Will these exhaust parts fit my specific year Peterbilt 389, and are there differences between model years?

Most exhaust components are compatible with Peterbilt 389 models from 2008 to present, but there are important variations. Pre-2013 models typically use 5-inch diameter systems, while 2013 and newer models may have different mounting brackets and heat shield configurations. Always verify your truck's build date and check for any fleet-specific modifications. Key differences include the DEF system integration on 2011+ models and changes to the exhaust mounting brackets in 2016+ trucks.

What's the difference between aluminized and stainless steel exhaust components, and which should I choose?

Aluminized steel parts cost 30-40% less and work well for moderate use, lasting 3-5 years in normal conditions. However, they're prone to rust in salt-heavy regions or with frequent washing. 304 stainless steel components resist corrosion better and typically last 7-10 years, making them ideal for coastal areas or heavy-duty applications. 409 stainless offers a middle ground with good durability at a lower price than 304. Consider your operating environment and how long you plan to keep the truck when choosing.

Can I install these exhaust parts myself, and what tools or expertise do I need?

Basic exhaust stack and tip replacements can be DIY projects requiring standard hand tools, jack stands, and about 2-3 hours. However, full system replacements involving the turbo downpipe, flex pipes, or emissions components often require specialty tools like exhaust hangers, torque wrenches, and possibly welding equipment. Common challenges include seized bolts on older trucks, alignment issues with aftermarket parts, and ensuring proper clearances. Professional installation typically runs $200-400 for complex jobs.

What exhaust tip styles and finishes are available, and how do they affect performance?

Popular styles include straight cut, curve cut, turn-down, and miter cut tips, available in chrome, polished stainless, or powder-coated black finishes. While tip style has minimal impact on performance, the exhaust stack diameter and length do matter. 5-inch stacks are standard, with 6-inch options providing a deeper tone but potentially requiring bracket modifications. Chrome requires regular polishing to maintain appearance, while polished stainless needs less maintenance. Black powder-coated options hide soot better but may show wear faster in high-heat applications.

Why are my new exhaust parts not fitting properly, and how can I ensure compatibility?

Fitment issues commonly stem from aftermarket frame modifications, non-standard exhaust routing from previous repairs, or mixing OEM and aftermarket components. Measure your current system's diameter, bracket spacing, and overall length before ordering. Pay special attention to cab-to-sleeper gaps, as extended and custom sleepers may require different stack lengths. Some aftermarket parts may need minor adjustments like drilling new bracket holes or using adapter clamps. When in doubt, provide your OEM to ensure you receive the correct OEM-specification parts.
