Q: How do I fix load muffler noise from my Lexus RX 300

asked by on

Very loud and gets louder at higher speeds

My car has 100000 miles.
My car has an automatic transmission.

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.
