BMW M5 Exhausts

Your factory BMW M5 exhaust removes the noxious fumes produced when the sports car's engine burns fuel. It works in stages. The first is your catalytic converter. The "cat" captures pollutants, safely turning them them into water vapor and carbon dioxide in a contained chemical reaction. Then second is your exhaust manifold. This part collects the gas, passing it through your exhaust pipe while your resonator and muffler make sure it flows as well as it can. The last stage is your muffler's tail pipe. It expels the cleansed exhaust fumes into the air. The process protects you and your passengers and the environment while keeping operational noise down. When and how often you should replace an exhaust depends on your driving conditions. A catalytic converter, for instance, lasts 100,000 miles, but a muffler or resonator can last as little as 2 to 4 years. A better way to figure out a maintenance schedule is to look for signs of exhaust problems -- a Check Engine light, odd muffler or exhaust pipe noise, a rotten-egg smell, and loss of fuel economy. If you experience any, the best way to determine if your exhaust is the cause is to do an inspection.
