School Bus Exhaust

With over 26 million students relying on school buses across the country, it’s no wonder that there is so much demand for exhaust replacement parts. These buses tend to put a lot of wear and tear on their extensive exhaust systems. 

The majority of school bus fleets are diesel as well, so issues with the diesel particulate filter (DPF) can affect performance or drop buses out of daily use entirely. Maintain proper emissions readings, get the best possible fuel efficiency, and enjoy more reliable performance from your school fleet by making timely repairs and upgrades with our school bus exhaust parts.

Why School Bus Exhaust Systems Commonly Need Repairs

School buses can travel tens of thousands of miles each over the course of a year. Combine that with the need to idle for 10 to 45 minutes during pickups and drop-offs, and you can start to understand why they need exhaust repairs every three to five years on average.

The exhaust parts most likely to wear out on school buses, regardless of manufacturer or design, include:

• Broken hangers and isolators, putting too much weight or vibration on the rest of the system
• Cracks around pipe elbows and joints that lead to exhaust leaks
• Clogs in the DPF system and damaged sensors that affect engine performance.

Upgrading and Updating Bus Exhaust Systems

In addition to repairing the stock exhaust systems on your school bus fleet, you may need to upgrade or update the exhaust pipes on older models. We carry a wide range of school bus exhaust parts in 3-inch, 4-inch, and 5-inch diameters to increase the flow through on vehicles with smaller pipes. 

You can also find 2.75-inch pipes and smaller for stock repairs, as well as all the larger exhaust pipes you need to keep exhaust temperatures low and reduce thermal damage to the entire system.

The School Bus Manufacturers We Cover

Here at Truck Pipes USA, we carry exhaust pipes and other parts for all of the major school bus manufacturers. That includes the companies that make up 90% of the current fleets in the US: International, Blue Bird, and Thomas Built. We also carry parts for Freightliner buses to ensure you can keep your fleet moving smoothly all school year long, whether all your buses are from the same manufacturer or you maintain a mix of makes and models.

Tips for Sizing School Bus Exhaust Parts

Many exhaust parts for school buses, especially elbows and straight pipes, require a match for both the inner diameter (ID) and outer diameter (OD). Other parts rely on only one of those measurements. 

You can start your search with the basic make and model of your school bus, but be sure to verify the fit details with caliper measurements before ordering. Coordinate the details with your mechanic provider.
