Ask any of our auto parts specialists at Merle's Automotive Supply and they will tell you to have your O2 sensor inspected regularly. Oxygen sensors work in conjunction with your catalytic converter to monitor the amount of oxygen in your car's exhaust system. Your O2 sensor determines if your air to fuel ratio is balanced in real-time as you accelerate or idle. It helps your engine controller adjust the flow of fuel to maintain optimum oxygen to fuel mixture.

So whether you are looking to make your vehicle as quiet as possible, or one that announces your arrival, at Merle's Automotive Supply, we have a performance muffler for you.
