Your exhaust and emissions system does far more than quiet your engine — it controls harmful emissions, protects engine performance, and ensures your vehicle stays compliant with local and federal regulations. At By The Book Diesel & Auto Repair, we provide complete exhaust and emissions service for gas and light-duty diesel vehicles, using advanced diagnostic equipment to identify issues quickly and accurately.
Exhaust leaks, clogged catalytic converters, failed DPF systems, or malfunctioning sensors can cause reduced power, poor fuel economy, diesel smoke, strong exhaust odors, or a persistent check engine light. These issues are often early signs of bigger problems, especially on modern diesel platforms with complex emissions systems.
Our technicians service the entire exhaust and emissions system from end to end — including catalytic converters, mufflers, exhaust manifolds, gaskets, sensors, EGR valves, DPF filters, SCR components, and DEF systems. We use smoke testing and diagnostic scanning to pinpoint the exact cause of the problem, preventing guesswork or unnecessary parts replacement.
For diesel trucks, we specialize in solving emissions-related issues on Powerstroke, Duramax, and Cummins engines. Whether your vehicle needs a DPF regeneration, DEF system repair, NOx sensor testing, or EGR service, we have the tools and experience to restore proper function and prevent further damage.
Routine emissions maintenance is also essential. Replacing sensors, fixing small leaks, or cleaning carbon buildup can drastically improve performance and fuel efficiency while helping you avoid costly repairs down the road.
At By The Book Diesel & Auto Repair, we take pride in providing honest recommendations, clear communication, and high-quality repairs performed the right way. Whether you’re dealing with a loud exhaust, an emissions failure, or a check engine light, you can count on our team to fix the issue quickly and correctly.
