Toyota Prius Replacement Muffler Information


The muffler on your Toyota Prius serves two functions. It dampens the noise of engine explosions, and it vents hot, potentially poisonous exhaust fumes away from the occupants of the car, and out through the tailpipe. When your Toyota Prius's muffler isn't functioning correctly, other people will be able to hear your car from many blocks away. Your Prius may also flunk mandated emissions test many states require before they will reregister your automobile. PartsGeek.com sells replacement mufflers for the Toyota Prius.

Mufflers are actually pretty nifty devices. Their chambers are specially engineered to create pressure waves of an opposite amplitude to the sound waves from your engine. This has the effect of canceling out engine noises. This process creates a certain amount of back pressure, which reduces the performance of your engine somewhat. That's the reason why so many racing cars don't bother with mufflers.


They are available for the following Toyota Prius years: 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 09, 08, 07, 06, 05, 04, 03, 02, 01.

Research on Muffler for Toyota Prius

Toyota Prius Muffler

The Toyota Prius is one of the most reliable vehicles on the road, but that’s just one of the bonuses of owning one. You probably got it because it’s also one of the most fuel-efficient vehicles in the world, and you care about keeping your emissions low. You might not always think of noise as a pollutant too, but it is. That’s why cars are built with mufflers. If you’re ever curious to know what the world would sound like without mufflers, go to a car race. Hear that roar? That’s what your engine sounds like with nothing to damp the noise. So if you’re having problems with your Toyota Prius muffler, get it replaced right away to keep your noise emissions low.

At PartsGeek.com we take pride in offering the most competitive prices on millions of parts. We carry Toyota Prius mufflers by dependable brands like Walker and Bosal. Our 30-day return policy and excellent customer service are here to make sure you get exactly what you’re looking for.

What is a muffler?

A muffler is a component of the exhaust system. As exhaust and the loud noises of your engine move through your muffler, it both cancels out and muffles the noise so your vehicle runs quieter. It also passes the exhaust on so it can be directed away from the vehicle. Without a muffler, your vehicle is extremely noisy.

How much does a Toyota Prius muffler cost?

A replacement muffler for a Toyota Prius will run you between $82 and $106 at PartsGeek.com.

How does a muffler work?

Your Toyota Prius muffler is a pretty remarkable bit of engineering. As a sound wave enters your muffler it moves into the resonator chamber, which creates a kind of echo by bouncing the wave back toward the entrance. Waves entering and waves bouncing back cancel each other out, eliminating the sound. This doesn’t erase all the sound, so your muffler also has an insulated body that absorbs noise, and a series of pipes with small holes that also allow for some noise cancellation in the main chamber.

Reviewer: so quiet

My wife's Prius is back in stealth mode now, thanks to this quiet muffler. Every this lined up just right and was easy to install. It took me an hour to get the exhaust system apart due to rusted nuts that resisted PB Blast and had to be cut off with a sawzall. Then 15 minutes to put it back together again. Very happy.
