Emission System and Exhaust
From the headers to exhaust, the emission system is an integral yet often overlooked item when it comes to vehicle maintenance and repairs. Cleaning and discarding the waste gases from the engine's combustion cycle, the exhaust system is the last step for the power plant of your BMW.
Aside from failing a smog or CARB test, a faulty emission system can lead to lower mileage realizations, foul-smelling or black-colored exhaust fumes, or louder than normal vehicle operation. Autobahn Automotive is fully capable of testing, diagnosing, and repairing emissions systems including the muffler, catalytic converter, piping, heat shields and various other emissions components. We utilize electronic testing to gauge on-board emissions sensors, and stock most parts that may need replacement to ensure your BMW runs smoothly and quietly.
For the enthusiast, we can recommend aftermarket and BMW-approved headers, mufflers, exhaust tips, and catalytic converters that can add a few horsepower to your vehicle while still maintaining emissions certification, with installation typically being the same or next day. An aftermarket exhaust not only aides in the aesthetics of a vehicle, but can help air to exit more smoothly and quickly from the car, which in turn has a positive effect on the overall efficiency and power of the engine, with durability and good looks to boot!
