Exhaust Repair
Concord, NC
Manifold, turbo pipes, muffler, exhaust brake, flex joints, custom fabrication — CTR provides complete diesel exhaust repair for all commercial truck brands. DOT compliant.
Exhaust System Repair Experts
A commercial truck's exhaust system operates in extreme conditions — temperatures exceeding 1,200°F at the manifold, severe thermal cycling, road vibration, and corrosive environments. Every component from manifold to tailpipe is subject to failure.
CTR provides complete diesel exhaust repair including manifold welding, turbo pipe fabrication, flex joint replacement, exhaust brake service, muffler replacement, and custom fabrication. We use the correct materials for each temperature zone.
Located on Armentrout Drive directly off I-85 at Exit 58. All repairs backed by our 3-year, 36,000-mile warranty.
Custom Fabrication
Custom pipe sections, adapters, and routing solutions in stainless, aluminized, or mild steel.
Exhaust Brake Service
Butterfly valve, VGT, actuator, and control system — critical safety feature.
3-Year, 36K Warranty
Industry-leading warranty on all exhaust repairs. Parts and labor covered.
DOT Compliant
All repairs meet FMCSA exhaust system requirements for DOT compliance.
Complete Exhaust Repair Services
From leak detection to custom fabrication. Click any service for details.
Visual inspection (soot staining), audible detection, and pressure/smoke testing. Leaks repaired by tightening connections, replacing gaskets and clamps, welding cracks, or replacing failed sections.
Warning Signs of Exhaust Problems
Exhaust Smell in Cab
Exhaust leak allowing fumes into the driver's breathing space. Carbon monoxide hazard.
Louder Than Normal Exhaust
Leak, muffler failure, or pipe separation. DOT compliance concern.
Visible Soot at Connections
Gas-tight seal has failed. Indicates active exhaust leak.
Exhaust Brake Not Working
Valve, actuator, or control fault. Safety concern in hilly terrain.
Check Engine Light
Exhaust leaks near sensors trigger fault codes affecting aftertreatment.
Loss of Power
Significant leaks upstream of turbocharger reduce boost pressure.

Understanding Your Exhaust System
A commercial truck exhaust system operates across a wide temperature range — from 1,200°F+ at the manifold to ambient at the hangers. Each component requires specific materials and repair techniques matched to its operating environment.
Exhaust Manifold
Collects exhaust from cylinders. Cast iron, 1,200°F+. Subject to thermal stress cracking and warping.
Turbo & Up-Pipes
Highest-temperature pipes. Stainless steel, 1,000–1,200°F. Flex joints absorb thermal expansion.
Aftertreatment Section
DOC, DPF, SCR connections. Stainless steel, 400–1,000°F. Gaskets and clamps critical.
Muffler & Tailpipe
Noise reduction and exhaust routing. Aluminized steel, 200–400°F. Corrosion is primary failure mode.
Exhaust Brake
Butterfly valve or VGT restricts flow for engine braking. Critical safety component in hilly terrain.
Hangers & Clamps
Support exhaust weight and accommodate expansion. Failed hangers cause vibration damage.
Built for Heavy Duty
CTR's facility on Armentrout Drive has the welding and fabrication equipment for complete exhaust system service — from manifold welding to custom pipe fabrication. Directly off I-85 at Exit 58.
Fleet Exhaust Maintenance
Exhaust system inspection in fleet PM programs with priority service. Proactive inspection catches developing leaks, corroded components, and failing hangers before DOT violations or performance problems.
