Exhaust System Repair & Service
Need exhaust repair in Thousand Oaks? Your exhaust system does more than reduce noise – it routes dangerous fumes away from the cabin, reduces emissions, and helps your engine run efficiently. At Gallardo's Automotive Service, we diagnose and repair all exhaust system problems to keep you safe and your vehicle running cleanly.
Warning Signs of Exhaust Problems
Exhaust problems can be dangerous. Don't ignore these warning signs:
Sounds
- Loud rumbling or roaring – exhaust leak or failed muffler
- Hissing or popping – leak in exhaust manifold or pipe
- Rattling from underneath – loose heat shield or failing component
- Ticking at startup – exhaust manifold leak
- Louder than normal acceleration – hole or crack in exhaust
Smells and Fumes
- Exhaust smell inside vehicle – DANGEROUS, stop driving immediately
- Rotten egg smell – catalytic converter problem or fuel issue
- Strong exhaust odor outside – rich fuel mixture or catalyst failure
- Sweet smell – coolant leak into exhaust (head gasket issue)
Visual Signs
- Rust holes in pipes or muffler
- Black soot around exhaust joints – leak at connection
- Visible damage to exhaust components
- Dragging exhaust pipe – broken hanger
Performance and Emissions
- Reduced fuel economy – exhaust restriction affecting engine
- Loss of power – clogged catalytic converter
- Check engine light – catalyst efficiency codes
- Failed emissions test – exhaust system malfunction
How Your Exhaust System Works
Exhaust Manifold
Collects exhaust gases from the engine cylinders and directs them into the exhaust system. Manifold leaks cause ticking sounds and can affect engine performance.
Catalytic Converter
Converts harmful pollutants (carbon monoxide, hydrocarbons, nitrogen oxides) into less harmful emissions. Required by law and monitored by the emissions system.
Oxygen Sensors
Measure oxygen content in exhaust to help the engine computer adjust fuel mixture. Upstream sensors control fuel mixture; downstream sensors monitor catalytic converter efficiency.
Muffler and Resonator
Reduce exhaust noise to acceptable levels. Mufflers use internal chambers and baffles to cancel sound waves.
Exhaust Pipes and Hangers
Route exhaust from manifold to tailpipe. Hangers secure the system and isolate vibration from the vehicle body.

Frequently Asked Questions
Is exhaust smell in my car dangerous?
Yes, very dangerous. Exhaust contains carbon monoxide, which is odorless, colorless, and deadly. If you smell exhaust inside your vehicle, open windows immediately and have the exhaust system inspected right away.
Why is my catalytic converter so expensive?
Catalytic converters contain precious metals (platinum, palladium, rhodium) that serve as catalysts for the chemical reactions that reduce emissions. California-compliant converters must meet strict efficiency standards, adding to cost.
Can I pass smog with a bad catalytic converter?
No. California smog tests check catalytic converter efficiency via OBD-II monitors. A failing converter will set trouble codes that cause automatic test failure.
Why does my exhaust make a ticking sound?
Ticking at startup that fades as the engine warms usually indicates an exhaust manifold leak. The leak seals somewhat as metal expands from heat. This should be repaired to prevent further damage and exhaust fume entry into the cabin.
How long does an exhaust system last?
Original exhaust systems typically last 5-7 years or more, depending on driving conditions and climate. Vehicles driven in areas with road salt or near the ocean may experience faster corrosion.
