At HHH & Repair LLC, we understand that exhaust system issues can be a major headache for fleet truck owners. That's why we offer a range of exhaust system repair services to help keep your trucks running smoothly and safely, no matter what challenges they may face.
SCR Catalyst Cleaning
One of the most important services we offer is selective catalytic reduction (SCR) cleaning. The SCR is an essential component of your exhaust system, and it helps to reduce harmful emissions by converting nitrogen oxide into harmless nitrogen and water vapor. Over time, the SCR can become clogged with soot and other contaminants, which can lead to decreased efficiency and increased emissions. Our expert technicians can perform thorough cleaning of your SCR to help ensure optimal performance and efficiency.
DOC Cleaning
We also offer diesel oxidation catalyst (DOC) cleaning, which is another important component of your exhaust system. The DOC helps to reduce emissions by converting harmful pollutants into less harmful substances. Over time, the DOC can become clogged with soot and other contaminants, which can lead to decreased performance and efficiency. Our team can perform thorough cleaning and maintenance of your DOC to help ensure optimal performance and reduced emissions.
Exhaust Leak Repairs
In addition, we also offer exhaust leak repairs, which are essential for ensuring the safety of your drivers and the environment. Exhaust leaks can allow harmful gases and pollutants to enter the cab of your truck, which can cause health problems for your drivers and other road users. Our technicians can diagnose and repair exhaust leaks quickly and effectively, helping to keep your trucks safe and compliant with all applicable regulations.
How Exhaust Restriction and Backpressure Affect Diesel Performance
Diesel exhaust needs to move through the exhaust and aftertreatment system without excessive restriction. When flow becomes restricted, backpressure can increase and contribute to reduced engine power, sluggish acceleration, higher exhaust temperatures, or abnormal aftertreatment operation.
Restrictions may develop from damaged exhaust components, internal contamination, or problems within connected aftertreatment equipment. Diagnostic testing helps determine where resistance is occurring rather than assuming the engine itself is responsible for the performance loss.
Diagnosing Exhaust Temperature and Sensor-Related Problems
Modern diesel exhaust systems rely on sensors to monitor temperatures and other operating conditions throughout the aftertreatment process. Incorrect sensor readings, damaged wiring, or failed components can trigger warning lights and affect how the system manages emissions.
Technicians can compare sensor data, fault information, and actual system behavior to determine whether the issue comes from the sensor itself or from a real exhaust condition. This is especially important when multiple exhaust or aftertreatment codes appear at the same time.
Why Exhaust Heat Damage Should Be Investigated
Exhaust components operate at high temperatures, particularly during regeneration and heavy engine load. Cracked piping, failed insulation, loose connections, or abnormal exhaust temperatures can expose nearby wiring, hoses, and other components to excessive heat.
Inspecting heat-related damage can help identify both the failed exhaust component and any surrounding parts that may have been affected. Addressing the source of excessive heat can reduce the chance of repeat damage after the repair.

What Causes Exhaust Leaks in Commercial Diesel Trucks?
Commercial diesel exhaust leaks can develop from cracked pipes, damaged clamps, failed gaskets, corrosion, or loose connections. An exhaust system inspection can locate escaping gases and damaged components so repairs can restore proper exhaust flow, reduce excessive noise, and prevent nearby parts from being exposed to excess heat.
How Do I Know If My Semi Truck Exhaust System Has a Leak?
A semi truck exhaust leak may cause louder engine noise, visible soot around joints, exhaust odors, reduced performance, or unusual heat near exhaust components. A technician can inspect piping, clamps, gaskets, and connections to locate the leak and determine which parts require heavy-duty exhaust system repair.
Why Is My Heavy-Duty Diesel Truck Producing Excessive Exhaust Smoke?
Excessive exhaust smoke can point to fuel delivery problems, poor combustion, turbocharger issues, engine wear, or aftertreatment faults. Heavy-duty diesel diagnostics can evaluate engine performance and exhaust components to determine why smoke has increased and whether engine or exhaust system repairs are needed.
