Adding your products to cart

Thinking of replacing a worn-out exhaust part, enhancing your look with chrome stacks, or doing a complete exhaust system overhaul? Our aftermarket diesel exhaust components are ready to help your rig breathe better, sound stronger, and last longer.

Why Upgrade Your 357/378 Semi Truck Exhaust System?

The exhaust system isn’t just about noise—it’s about power, efficiency, and engine protection. A well-maintained or upgraded exhaust: - Improves airflow and reduces backpressure - Boosts fuel economy and throttle response - Lowers exhaust gas temps (EGTs) - Extends engine performance life - Adds a clean, aggressive look with chrome or black stacks Whether you're running a vocational setup with a 357 or hauling freight in a 378, better exhaust means better performance. Help your exhaust with superior under-the-hood airflow with AC parts for your Peterbilt 357/378 or upgrade your Peterbilt 357/378 engine performance components. What You'll Find in This Lineup: Our Peterbilt 357/378 exhaust collection includes: - Chrome exhaust stacks: Straight, miter, curved, or flat tops to match your rig’s personality - Exhaust piping & elbows: Smooth mandrel bends for efficient flow - Mufflers: Quiet things down without choking performance - Diesel Particulate Filters (DPF): Reduce emissions while keeping your truck compliant - Clamps, hangers & brackets: Keep your system tight and rattle-free - Complete exhaust kits: Everything you need to replace or upgrade in one go
These parts are built from heavy-duty steel or stainless steel, designed to resist corrosion, vibration, and extreme heat. So whether you're customizing for show or replacing for everyday use, you're getting durability you can count on.

Make Your Exhaust Work Harder (and Look Better)

From rugged job sites to long highway runs, your truck’s exhaust system is working nonstop. Upgrading with high-quality aftermarket parts gives you: - Better airflow = more power - More efficient emissions control - That bold, polished big rig look to stand out on the road
We stock direct-fit parts for Peterbilt 357 and 378 models. That means less time fighting with modifications and more time on the road. Plus, we carry universal and customizable options so you can dial in the exact look and function you're going for.

Frequently Asked Questions About Peterbilt 357/378 Exhaust Parts

Will these exhaust parts fit my specific year Peterbilt 357 or 378?

Most aftermarket exhaust components for Peterbilt 357/378 models are designed to fit trucks manufactured between 1987-2007. However, there can be variations based on engine type and chassis configuration. We recommend checking your truck's specific model year and engine (Cat C15, Cummins ISX, etc.) before ordering. If you're unsure, contact us with your OEM and we'll help verify compatibility.

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

Aluminized steel exhaust parts offer good corrosion resistance at a lower price point and typically last 3-5 years under normal conditions. Stainless steel components cost more upfront but provide superior durability, lasting 7-10+ years and maintaining their appearance better. For trucks operating in harsh weather conditions or with high annual mileage, stainless steel provides better long-term value.

Do I need special tools or modifications to install these exhaust parts?

Most exhaust stacks, elbows, and straight pipes can be installed with basic hand tools and proper clamps. However, some installations may require cutting or adjusting existing pipes for proper fitment. We recommend having exhaust clamps, high-temperature sealant, and a reciprocating saw on hand. Professional installation typically takes 2-4 hours depending on the complexity of your setup.

What diameter exhaust pipe should I use for my Peterbilt 357/378?

Standard exhaust diameter for most Peterbilt 357/378 trucks is 5 inches, though some high-performance applications use 6-inch systems. Your existing exhaust diameter should match throughout the system to maintain proper backpressure. Measure your current exhaust outlet at the turbo or manifold to confirm the correct size before ordering replacement parts.

How do I prevent exhaust stacks from discoloring or rusting?

Chrome stacks require regular cleaning with chrome polish and should be wiped down after exposure to rain or road salt. Stainless steel stacks can be maintained with stainless steel cleaner and will naturally develop a light patina over time. Apply high-temperature wax or coating every few months for added protection. Avoid using abrasive cleaners or steel wool, which can scratch the finish and accelerate corrosion.
