Peterbilt 367 Exhaust Parts

Whether you’re chasing more power, a cleaner burn, or that aggressive chrome look—upgrading your exhaust setup is one of the best moves you can make.

Why Enhance Your Peterbilt 367 Exhaust System?

Your exhaust system is more than just pipes and stacks. It does the heavy lifting behind the scenes—removing heat, managing emissions, and keeping your diesel engine running efficiently. A worn or clogged system means lost power, more fuel use, and more downtime. An upgraded exhaust helps your engine breathe better, lowers backpressure, and boosts overall performance. And let’s be honest—it looks sharp too.

What Your Semi Truck Exhaust System Does

Here’s a quick breakdown of what your system includes: - Exhaust Manifold: Channels exhaust away from the engine safely. - Turbocharger: Uses exhaust pressure to boost engine power. - Exhaust Piping & Elbows: Routes gases from the manifold to the back of the truck. - Diesel Oxidation Catalyst (DOC): Converts harmful fumes into less toxic ones. - Diesel Particulate Filter (DPF): Captures soot before it hits the air. - Selective Catalytic Reduction (SCR): Reduces harmful NOx emissions using DEF fluid. - Muffler: Cuts down exhaust noise without choking airflow. - Stacks & Tips: Sends cleaned exhaust high above the cab while adding major visual style.
Each part plays a role in protecting your engine, meeting emissions rules, and keeping your rig road-ready. If you're looking for a comprehensive performance tune-up, invest in Peterbilt 367 AC components for stronger under-the-hood cooling and engine performance parts for the Pete 367.

Performance Upgrades That Pay Off

Upgrading to aftermarket exhaust parts in your Peterbilt 367 gives you better throttle response, less restriction, and lower EGTs (exhaust gas temps). That means more reliable power and improved fuel efficiency on long hauls. You’ll also get smoother idling, cleaner emissions, and less strain on your engine over time. Whether you’re replacing your muffler, upgrading to chrome 7-inch stacks, or adding new elbows and clamps, these parts are built tough. Stainless steel, aluminized tubing, and high-heat finishes help resist corrosion, warping, and cracking. You’ll find options that fit OEM specs or go full custom for a show-ready rig.
