Frequently Asked Questions
Can I drive with an exhaust leak?
Small leaks aren't immediately dangerous but should be fixed soon — exhaust fumes contain carbon monoxide. Loud exhaust leaks near the engine are more concerning as fumes can enter the cabin. Don't ignore exhaust leaks, especially if you smell fumes inside the car.
How long does an exhaust system last?
In dry climates: 8-15 years. In salt/rust belt states: 5-8 years before components start failing. Stainless steel exhausts last much longer. Catalytic converters typically last 10-15 years or 100,000+ miles.
Why does exhaust system repair cost different in St. Louis than other cities?
St. Louis's costs reflect local labor rates driven by the diversified economy, varied climate conditions that affect materials and scheduling, and moderate permitting requirements. The balanced labor market also influences competitive pricing.
