Exhaust problems rarely happen without warning. Recognizing these early signs can help you address issues before they become dangerous or expensive.
Loud Exhaust Noise
A sudden increase in exhaust volume usually indicates a hole, crack, or disconnected component. The noise may be a rumble, roar, or hissing sound depending on where the leak is located in your system.
Rattling or Vibration
Loose heat shields, worn hangers, or damaged components can rattle against your vehicle's undercarriage. You may feel vibration through the floor or hear metallic rattling sounds while driving.
Exhaust Smell Inside Vehicle
If you smell exhaust fumes inside your car, you have a dangerous leak allowing gases to enter the cabin. This is a serious safety concern because exhaust contains deadly carbon monoxide.
Decreased Fuel Economy
Exhaust leaks before the oxygen sensors can cause your engine computer to adjust the fuel mixture incorrectly, resulting in poor fuel economy and reduced engine performance.
Check Engine Light
Problems with the catalytic converter or oxygen sensors will trigger your check engine light. These components are critical parts of your exhaust system that affect emissions and performance.

Exhaust System Repair you can count on:
Your exhaust system consists of multiple interconnected components running from your engine to the tailpipe. We service and repair every part of this critical system.
Exhaust Manifold
Collects exhaust gases from engine cylinders and routes them into the exhaust system. Cracked manifolds or failed gaskets cause exhaust leaks near the engine and create a distinctive ticking noise that increases with engine speed.
Catalytic Converter
Reduces harmful emissions by converting toxic gases into less harmful compounds. Failed converters cause check engine lights, poor performance, and sulfur smells, requiring expensive but necessary replacement.
Oxygen Sensors
Monitor exhaust gases and help your engine computer adjust the fuel mixture for optimal performance. Failed sensors cause poor fuel economy, rough idling, and check engine light activation.
Exhaust Pipes and Muffler
Connect exhaust components and reduce engine noise. Pipes rust from inside out due to Indiana's harsh climate, while mufflers develop holes in their outer shells or internal baffles fail from corrosion.
Hangers and Clamps
Secure the exhaust system to your vehicle's undercarriage. Worn rubber hangers and corroded metal clamps allow the system to sag and contact other components, causing rattling and potential damage.

Our ASE-certified technicians follow a thorough process to ensure your exhaust system repair is done right the first time with quality parts and proper installation.
Complete System Inspection
