Exhaust System Inspection $79.99 - $89.99 Get a Quote

You will need to have the exhaust inspected to see where the exhaust is leaking. Sometimes the flex pipe connected to the engine goes bad and leaks. Other times the muffle can rust through causing this.

Have a muffler shop or mechanic inspect your exhaust system to quote the repair. Have them show you what exactly is wrong. Be sure to check it yourself to avoid replacing the entire unit when you only need a piece of the system.
