The longer the pipes, the more residence time the exhaust has to bounce through the tube. A vehicle’s exhaust system is usually between 8 and 16 feet long. The pressurized gas speeding down the exhaust pipes carries the noise with them.

Performance muffler or not, if you just want a quieter exhaust system, check out our article How to Quiet a Loud Exhaust. This eardrum rupturing cacophony occurs thousands of times a minute. The gasses blast out the exhaust ports between 80 and 100 psi pressure and fire into the manifold at speeds of 2800 fps. It is the explosion of the gasses from the fuel-oxygen mixture. The better it does at both, the greater the expense to you.Įxhaust noise originates in the combustion chamber of the engine.

Improving the airflow into the muffler and reducing back pressure from the engine is what a performance muffler does. It’s a fine-tuned balance with a lot of science involved. What is Performance MufflerĪ performance muffler is fabricated to maximize sound suppression while minimizing airflow restriction. The layout of the system produces a growl, whine, purr, or super quiet exhaust based on its design, and the frequencies it controls. They’re known as Cat-back (Catalytic converter back) changes. But, modifications from the converter to tailpipe can be made. In most jurisdictions, the law prohibits tampering with the catalytic converter. It then runs through a catalytic converter that converts carbon monoxide into carbon dioxide. A variety of fabrication strategies reduce exhaust volume and minimize engine performance lose.Īn automotive exhaust system begins at the exhaust manifold. Mufflers are engineered to perform differently. However, the more restricted the airflow, the more restrictive the backpressure.īackpressure is what hinders engine performance.
