Your Toyota MR2 exhaust works in stages to clean and get rid of the fumes its engine creates when it burns fuel. A catalytic converter begins the process. It catches pollutants and safely converts them from noxious chemicals into water vapor and carbon dioxide. Your exhaust manifold then gathers the gas and sends it down your exhaust pipe while your resonator and muffler help ensure it flows as best it can. Lastly, your tail pipe scatters cleaner fumes into the air, where they dissipate, protecting both you and your passengers and the environment.

When Should I Replace Exhaust Parts, and How Often?

That depends on the part, how you drive, and what conditions you drive in. A catalytic converter may last 100,000 miles, but mufflers and resonators last anywhere from 2 to 4 years. A better way to figure out the answer is to look for symptoms of exhaust problems -- more than just a lit Check Engine light. Those signs include everything from weird exhaust pipe and muffler noises to declining fuel economy and even weirder smells, most notably, of rotten eggs. If your sports car shows any of these, do an inspection to determine whether your exhaust is the cause. If you need to order new exhaust parts, buy genuine Toyota. Your OEM guarantees their compatibility with your Toyota MR2, after all. You're in luck as well. You can order what you need online from our auto parts counter in just a few clicks!
