Excess noise, reduced power, or a check engine light can all signal problems in your truck’s exhaust system. We provide comprehensive heavy-duty exhaust system repairs to restore performance and keep your emissions in check.
Truck Exhaust Repair in Darlington, SC
We service everything from exhaust manifolds and gaskets to mufflers, pipes, and aftertreatment components. Our diagnostics start with a backpressure and smoke check, followed by an inspection of the diesel particulate filter (DPF), exhaust gas recirculation (EGR) valve, and selective catalytic reduction (SCR) system. We replace rusted pipes, repair broken hangers, and resolve DEF delivery issues to ensure your truck runs clean and compliant.
Common exhaust system repairs include:
- Exhaust manifold gasket and leak repair
- DPF cleaning or replacement
- SCR and DEF system diagnostics
- Muffler and tailpipe replacement
- EGR and DOC component servicing
We also address common signs like black smoke, loss of power, hissing or rumbling sounds, and emissions-related fault codes.

Can I Drive With an Exhaust Leak?
It’s not recommended. Exhaust leaks can allow harmful fumes into the cab and lead to performance loss or emissions violations. If your truck is hissing, rumbling, or producing excess smoke, bring it in for service.
What Does the SCR System Do?
The Selective Catalytic Reduction (SCR) system reduces nitrogen oxide (NOx) emissions by injecting DEF into the exhaust stream. It’s critical for emissions compliance and performance in modern diesel engines.
