About Our Heavy-Duty Exhaust System Repair Services for Trucks & Fleets
Exhaust systems are very important to every vehicle on the road. They are especially important in heavy-duty 18-wheelers, for the bigger the engine, the more emissions. Exhausts are designed to suppress noise through a series of carefully designed tubes, mufflers, and catalytic converters. Alongside noise suppression, exhaust systems are also designed to protect the driver from harmful fumes. Your exhaust is generally designed in such a way that emissions exit far from the passenger compartment. A third major responsibility of exhaust systems is the protection of our atmosphere and environment. Using catalytic converters and other emissions control systems, your exhaust limits the amount of carbon that’s emitted into the atmosphere.
Here at Integrity Fleet Services, we are exhaust experts. We understand that most truck drivers are in a rush to get back out on the road, so we prioritize fast and efficient service. Whether you need a new catalytic converter or need holes patched, our technicians will have you covered. Our technicians are fully equipped and qualified to weld, repair, and maintain your exhaust systems at a price that won’t break the bank.
Tell-Tale Symptoms of a Bad Exhaust System
Extremely Loud Engine
If your engine is very loud while running, chances are you have an exhaust leak. The louder your engine is, the more severe the leak. Generally, exhaust leaks are easy to fix. They typically happen when rust and corrosion eat away at your metal exhaust pipes. Sometimes road debris is also a causal factor. Regardless, our technicians will patch your exhaust and have you back out on the road in no time.
Fumes in Passenger Compartment
If you have an exhaust leak that’s allowing fumes to escape close to your passenger compartment, chances are fumes are entering the passenger compartment. This is a very dangerous issue. You and your passengers are at risk of severe health issues. We highly recommend you stop operating your heavy-duty 18-wheeler if you start to experience headaches, migraines, nausea, or any other related symptoms.

Why is my semi-truck exhaust louder than normal?
A sudden increase in exhaust noise may come from cracked piping, loose connections, damaged clamps, a failing muffler, or another exhaust leak. Semi-truck exhaust repair can inspect the system for openings and damaged components, helping locate the source instead of replacing parts based only on where the noise is heard.
What causes an exhaust leak on a commercial diesel truck?
Commercial diesel truck exhaust leaks can develop from cracked piping, failed connections, loose clamps, corrosion, or damaged exhaust components. Heat and vibration can contribute to wear over time. A diesel exhaust repair inspection can trace the leak and determine which components need repair or replacement.
Why does my diesel truck smell like exhaust inside or around the cab?
Exhaust odors around the cab may indicate a leak from piping, connections, or another damaged part of the exhaust system. Because exhaust gases should remain contained, a diesel truck exhaust system inspection should locate the source and determine what repairs are required before the problem becomes more severe.
Heavy-Duty Truck & Trailer repairs

Axle Repair
18-wheelers and other heavy-duty commercial vehicles require hefty axles in order to mitigate the strain of intense torque. Light-duty axles on a heavy-duty rig would likely snap, as the force they’d be under would be nearly unfathomable. Whether through age, use, or exposure to the elements, axles need to be serviced routinely. Here at Integrity Fleet Services, we consider ourselves to be axle experts. Our skilled technicians are well-equipped to handle any and all axle problems.

Body Work
Your heavy-duty vehicle’s body work is responsible for maintaining adequate aerodynamics, benefits your fuel efficiency, and protects your engine and other vital components. It also maintains the look and aesthetics of your vehicle! Here at Integrity Fleet Services, we offer an all-encompassing set of body services. Whether you got into an accident or simply want custom work, our highly trained bodywork professionals will get the job done.

Brake Repair
Heavy-duty commercial vehicles can carry or tow close to a hundred thousand pounds because of their powerful engine and strong drivetrain. Bringing a hundred thousand pounds to a stop requires a hefty amount of braking power, and as such, heavy-duty commercial rigs will generally have incredibly complex and powerful braking systems. Because of what heavy-duty air brakes do on a regular basis, they require significant repair and maintenance.

Coolant System Repair
All vehicles that use an internal combustion engine will use some sort of coolant system. Heavy-duty coolant systems are usually a lot larger and a lot more complicated than what you’d normally find in a small or even medium-sized automobile. Ultra heavy-duty radiators and large coolant line systems are designed to handle an incredible amount of heat produced by large diesel engines. Heavy-duty trucks would catastrophically fail without their coolant system, so maintenance is mandatory.

Diagnostics & Electrical Repair
Newer diesel models are full of electronics. They have a ton of sensors, huge computer units, and a crazy amount of wiring. This makes your diesel truck more prone to electrical issues. These issues can be quite complex, and often require hours' worth of troubleshooting. Computer diagnostic service is the process of connecting your equipment to our state-of-the-art diagnostic equipment and running tests. This allows us to quickly and accurately diagnose and repair your equipment the right way the first time.

DOT Inspection
If your heavy-duty commercial vehicle weighs more than 10,000 pounds, the US Department of Transportation requires you to obtain a DOT inspection certificate on an annual basis. Our technicians at Integrity Fleet Services can perform both State and Federal DOT compliant inspections. Besides ensuring your truck is safe and in peak operating shape, our DOT compliant inspection service will keep you fully compliant with the Department of Transportations rules and regulations.

Driveline Repair & Maintenance
Your driveline is responsible for taking your engine’s torque and transferring it to your wheels. This is typically done using a series of driveshafts and differentials. These components need to be maintained on a routine basis because replacing them altogether can be extremely expensive. One of the major component types in your driveline are your differentials. Your differentials take power from your driveshaft and transfer it to your drive axles. Here at Integrity Fleet Services, we offer an extensive selection of driveline repair and maintenance services.

Exhaust System Repair
Exhaust systems are very important for heavy-duty 18-wheelers, for the bigger the engine, the more emissions. Alongside noise suppression, exhaust systems are also designed to protect the driver from harmful fumes and protect our atmosphere and environment. Using catalytic converters and other emissions control systems, your exhaust limits the amount of carbon that’s emitted into the atmosphere. Here at Integrity Fleet Services, we are exhaust experts.

Express Lube
If you want your heavy-duty commercial vehicle to last a long time, you need to perform adequate preventative maintenance. Here at Integrity Fleet Services, we offer a service called Express Lube. This service will ensure everything from 18-wheelers to lighter-duty haulers receives adequate maintenance in a proactive way. Our techs here at Integrity Fleet Services believe that proactive maintenance is far more beneficial to you as the driver than that reactive repairs.

HVAC Maintenance & Repair

We know the ins and outs of 18-wheelers better than anyone. We’ll have your oil and fluid maintenance done in a jiffy so you can get back out on the road.

Suspension Maintenance & Repair
Your suspension is an extremely important part of your 18-wheeler. Not only is it responsible for holding up extreme amounts of weight, but it’s also responsible for keeping you and your passengers safe. Unlike smaller cars, 18-wheelers use complex air suspension systems. These systems are designed to give you the strength of leaf spring setups and allow for comfort when not hauling. They can be complex, and as such, require routine maintenance and inspection.

Transmission & Clutch Repair
Your transmission and clutch are incredibly important. They allow your engine’s power to be transferred to your drivetrain using a variety of gears. These gears optimize your engine’s power input so you can haul extreme amounts of weight with relative ease. Here at Integrity Fleet Services, we’re experts at maintaining transmissions, but we are also fully equipped to do any and all transmission repairs that come our way.

Wheel & Tire Repair
18-wheeler operators drive hundreds of thousands of miles throughout their careers. They travel vast distances in all types of weather, in all climate types. Over time, drivers are bound to experience some sort of tire damage. The most common form is a tire blowout due to road debris. Here at Integrity Fleet Services, we offer a full suite of tire repair options. Whether you want your tire simply repair or completely replaced, our technicians have your back.
