Exhaust Repair & Service in Columbus, OH

Your exhaust system does three jobs: it routes toxic gases away from the cabin, reduces engine noise, and controls emissions through the catalytic converter. When any part of that system develops a leak, corrodes through, or fails, the consequences range from annoying (a loud engine) to dangerous (carbon monoxide entering the cabin).

At Petty's Auto & Electric Service, we repair and replace every component in the exhaust system — from the exhaust manifold at the engine to the tailpipe at the rear. We also fabricate custom exhaust sections and hard-to-find pipes in-house, which is especially valuable for classic vehicles, older imports, and discontinued models where off-the-shelf parts simply don't exist anymore.

Ohio Winters Are Hard on Exhaust Systems: Road salt accelerates corrosion on the outside. Short cold-weather trips — where the exhaust never gets hot enough to evaporate internal condensation — cause rust from the inside out. If your exhaust has gotten louder over the winter or you see rust flaking off pipes and mufflers, spring is the time to get it inspected before a small hole becomes a complete failure.

Signs Your Exhaust System Needs Repair

Exhaust problems usually announce themselves — the trick is knowing what the symptoms mean and how urgent they are.

  • Engine is louder than normal — the most obvious sign of an exhaust leak; the closer the leak is to the engine (manifold, flex pipe), the louder it will be
  • Ticking or tapping on cold start that fades as the engine warms up — a classic symptom of an exhaust manifold crack or a failed manifold gasket; the metal expands as it heats and temporarily seals the gap
  • Exhaust smell inside the vehicle — this is a safety issue; if you smell exhaust in the cabin, something is leaking near the firewall or under the floor, and fumes are entering through seams or the HVAC system
  • Rattling or buzzing underneath the vehicle — a loose heat shield, broken hanger, or a failing catalytic converter with a deteriorating internal substrate
  • Check engine light with catalyst-related codes — P0420 or P0430 codes indicate the catalytic converter isn't performing efficiently; could be the converter itself or an upstream issue causing it to fail
  • Decreased fuel economy — an exhaust leak before the oxygen sensors throws off the air-fuel mixture, causing the engine to run rich and waste fuel
  • Visible rust, holes, or hanging pipes — if you can see damage from the outside, the problem is well past the early stages

Our Exhaust Services

We repair, replace, and fabricate exhaust components for all makes and models — including custom work for classic and vintage vehicles.

Exhaust Leak Diagnosis & Repair

We inspect the full system from manifold to tailpipe — visually, by sound, and with a smoke machine when needed to find leaks that aren't obvious. Repairs range from gasket replacement and welding to section replacement, depending on the location and severity of the leak.

Muffler Replacement

A failed muffler makes your vehicle loud, but it can also affect backpressure and engine performance. We replace mufflers with quality units that match your vehicle's specs — restoring quiet operation and proper exhaust flow.

Catalytic Converter Service

Catalytic converters can fail from age, contamination (coolant or oil entering the exhaust), or internal substrate breakdown. We diagnose whether the converter is the actual problem or whether an upstream issue is causing it to fail — because replacing a converter without fixing the root cause means the new one will fail too.

Exhaust Manifold Repair

Cracked manifolds and failed manifold gaskets cause exhaust leaks at the engine, affecting performance and sending fumes toward the cabin. We replace gaskets, repair or replace cracked manifolds, and address the warped or corroded studs and bolts that make manifold work challenging.

Custom Exhaust Fabrication

When off-the-shelf parts aren't available — classic vehicles, discontinued models, unusual configurations — we fabricate custom exhaust sections in-house. We bend, weld, and fit pipes to your specific vehicle rather than forcing a generic part that won't seal or last.

Oxygen Sensor & Emissions Diagnostics

Oxygen sensors monitor exhaust gas composition and feed data to the engine computer. A failed O2 sensor causes poor fuel economy, rough running, and check engine lights. We test sensor function with live data — not just code reading — and replace only the sensors that have actually failed.

Why Choose Petty's Auto for Exhaust Repair?

In-House Fabrication

We bend, weld, and build custom exhaust sections on-site. When parts aren't available off the shelf — especially for classic or discontinued vehicles — we make them.

Diagnose Before Replacing

A check engine light with a catalyst code doesn't always mean you need a new converter. We find the root cause first — it could be an O2 sensor, an engine issue, or a leak upstream.

Full System Expertise

Manifolds, flex pipes, catalytic converters, resonators, mufflers, hangers, heat shields, O2 sensors — we work on every component, not just the easy-to-reach ones.

Classic Vehicle Specialists

Hard-to-find exhaust parts for vintage vehicles are our wheelhouse. We fabricate what we can't source and ensure proper fitment on vehicles that no longer have factory support.

Exhaust Repair FAQ

Common questions Columbus drivers ask about exhaust problems and repair.

How do I know if my exhaust system has a leak?

A louder-than-normal engine is the most common sign, especially during acceleration. You may also hear ticking on cold start (manifold leak), smell exhaust inside the cabin, notice hissing underneath the vehicle, or see a drop in fuel economy. Any exhaust smell inside the vehicle is a safety concern and should be inspected promptly.

How much does exhaust repair cost in Columbus?

Muffler replacement typically runs $150 to $400. Pipe section replacement or welding is $100 to $300. Catalytic converter replacement is the most expensive at $800 to $2,500+ depending on the vehicle. Exhaust manifold repair ranges from $300 to $800. We inspect the full system and provide a written estimate before work begins.

Can you make custom exhaust parts for older vehicles?

Yes — we fabricate custom exhaust sections, adapters, and hard-to-find pipes in-house. This is especially valuable for classic cars, older imports, and discontinued models where OEM parts are no longer available. We bend, weld, and fit to your specific vehicle.

Is it safe to drive with an exhaust leak?

It depends on location. A small leak at the tailpipe end is mostly noise. A leak at the manifold or near the firewall is a potential carbon monoxide hazard — fumes can enter the cabin through the ventilation system or floor seams. If you smell exhaust inside the vehicle, have it inspected immediately and drive with windows cracked in the meantime.

Why is my catalytic converter so expensive to replace?

Catalytic converters contain precious metals — platinum, palladium, and rhodium — that do the actual emissions conversion work. The raw materials make up most of the cost. Vehicles with multiple converters or manifold-integrated units are even more expensive. The high value of these metals is also why converter theft has become common. We install quality replacements and can advise on anti-theft measures.

What causes exhaust systems to rust so fast in Ohio?

Two directions: road salt corrodes the outside, and moisture condensation rusts the inside. Short trips are especially hard on exhaust systems because the pipes never get hot enough to evaporate internal condensation. Ohio winters with heavy salting accelerate both. Stainless steel components last longer but cost more upfront.

Loud Exhaust, Exhaust Smell, or Check Engine Light? We'll Find It

From a simple muffler replacement to custom fabrication for a classic car, the team at Petty's Auto & Electric Service has the tools and experience to handle it. Serving Columbus, Westerville, Worthington, Gahanna, New Albany, Lewis Center, Powell, and the surrounding areas.
