What comes out of your car - is just as important as what goes in. The exhaust system on your car, truck, or SUV, is responsible for removing harmful gas emissions from the exhaust. The exhaust system on your vehicle is complex and is made up of multiple parts including the exhaust manifold, catalytic converter, exhaust pipes, oxygen sensor, and muffler. Your exhaust system does more than just keep your car quiet - it routes exhaust fumes away from the cabin, helps maintain optimum fuel efficiency, and reduces polluting emissions. In some cases, motorists will install aftermarket exhaust systems with the goal of generating more power or improving the sound of the exhaust note. If your exhaust system is in need of repair, replacement, or inspection, call us today at 703-956-9811, or schedule an appointment online at Old Ox Tire & Auto , in Sterling.
