High-Performance Header Upgrades
While exhaust manifolds and headers play a similar role, at Autotech of Danbury we know they are miles apart on performance. Headers are upgrade parts designed for performance applications, while exhaust manifolds come standard. Both move exhaust away from the cylinder head to the exhaust pipe. Most noticeably, headers and its companion gaskets and wider exhaust pipe are much louder than a traditional manifold. But more importantly, the header improves exhaust system performance.

• O2 Sensor Replacement: Ask any mechanic at Autotech of Danbury 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.
