Exhaust System Repair at Jefferson Auto Service
If your car is loud, smelly, or failing emissions, it’s time for professional auto repair from an experienced auto mechanic who knows exhaust systems inside and out. At Jefferson Auto Service, we provide expert exhaust diagnostics and repair for drivers in Harrison Township, Clinton Township, and Romeo. Whether it’s a rusted muffler, cracked manifold, or a failing catalytic converter—we’ve got your back (and your tailpipe).
From Noise Complaints to Emissions Failures—We Fix It All
Michigan winters are rough on exhaust systems. Rusted flanges, leaky joints, and broken hangers are common in our area—and they can cause everything from annoying noises to real performance and safety issues. At Jefferson Auto Service, we inspect the entire system from engine to tailpipe: manifolds, gaskets, flex pipes, catalytic converters, mufflers, and heat shields.
Whether you need a section replaced, a weld repaired, or the whole system redone, our ASE-Certified team will give you options. We’ll perform a Digital Vehicle Inspection (DVI), show you exactly what’s wrong, and help you choose a fix that makes sense for your vehicle and your budget.
