Muffler

Mufflers may have no place in some racecar drivers' vehicles, but for regular street-drivers like you, it's important that your vehicle sports a reliable muffler. Also called a 'silencer', it helps tone down your engine's exhaust sounds to more aurally-pleasing notes.

The muffler is designed to cancel out the loud sounds made by exhaust gases rushing out of your vehicle's tailpipe. This means you won't be waking the neighbors up and making a racket just by driving down the street.

Aftermarket silencers can also improve engine efficiency by reducing backpressure, preventing exhaust gases from re-entering the engine block and the cylinders.

More importantly, there are laws governing exhaust systems and exhaust noise levels on public roads. Yes, police officers can actually give you tickets if your vehicle's exhaust system is too loud. As stock mufflers get rusty and develop cracks or holes through the years, you might want to get a proper replacement.

This ensures that your vehicle's exhaust system makes as little noise as possible. Here at Auto Parts Deal, you have dozens of muffler brands and types to choose from.
