Here at Expressway Mechanic on Duty we have the expertise to repair exhaust systems, mufflers, flex pipes and catalytic convertors. We have pipe benders and welders so that we can fabricate an exhaust system for any car. We do dual exhausts and can usually repair exhaust pipes on an older exhaust system on most cars and trucks. We also can repair oxygen sensors and catalytic converters in some cases. Come on down to Expressway Mechanic on Duty located at 4002 Lagrange Street, corner of Sylvania Avenue.
