The Chevrolet Trailblazer Muffler enables a car to operate with less unpleasant sound. The typical internal combustion engine is quite audible - to reduce the noise to a bearable noise level, a Chevrolet Trailblazer has a muffler.

Research on Muffler for Chevrolet Trailblazer

Chevrolet Trailblazer Muffler

Designed for comfort and utility, the Chevrolet Trailblazer is a precision machine built with only the highest quality parts. Keeping your SUV’s noise level within an acceptable range, the specially designed muffler allows you and your passengers to have a quiet ride.

If your muffler needs replacement, shop at PartsGeek.com to find the finest quality replacement parts for your vehicle. Your purchase is backed by a 30-day money back guarantee.

What is muffler?

Also known as a silencer, the muffler attaches to the bottom rear of the vehicle and works by decreasing the noise level emitted by the exhaust system of the internal combustion engine.

How much does a muffler cost?

Here at PartsGeek.com, mufflers for your Chevrolet Trailblazer range in price from $80 to $150. Use the online catalog to find just what you need to keep your vehicle on the road.

How does a muffler work?

The muffler is a long pipe filled with finely tuned channels, holes, and tubes which have been arranged to cause the sound from your combustion system to lose energy as it passes through. By losing energy, the loud noise is subdued. The alignment of the channels and holes is so precise that as the sound waves leave the engine, their movement through the network within the muffler combines them with one another and causes the waves to cancel each other out. This alignment reduces the noise.

What are the parts of the muffler?

The muffler contains four parts. Each is an integral component of the system as a whole.

  • Inlet: Attaches to the engines exhaust system and allows the exhaust gases and residual sound to enter.
  • Resonator: The intricate chamber where the sound waves are combined and cancellation begins.
  • Tubes: Two tubes with perforations that cancel further sound waves as they move through it.
  • Outlet: The piece which allows the sound and exhaust gas to exit the exhaust system.

Mufflers available for the following Chevrolet Trailblazer years: 2009, 2008, 2007, 2005, 2004, 2003, 2002, 09, 08, 07, 05, 04, 03, 02.
