The muffler in your Buick Park Avenue reduces the loud noise produced by exhaust system pressure throughout engine operation. Together with this noise, the exhaust system carries fumes, water and acids produced throughout engine combustion. This toxic mixture of exhaust by-merchandise finally corrodes the exhaust pipes and muffler after a interval of service. In case your muffler has already developed a leak, poisonous gases might find their method into the passenger compartment and put the lives of anyone on board in danger. Substitute the rusted muffler as soon as possible.
