Turbo Sound Exhaust Muffler Pipe

OverviewTurbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as 'spooling up', which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.The whistle tip is a small metal plate with a central hole that is welded into the inner tip of the exhaust pipe. As exhaust gases are forced through the exhaust system under pressure, they pass through the hole and generate a whistling sound similar to a steam locomotive whistle.If your turbo starts to make a noise similar to an emergency services siren, or a dentist drill, it is a sure sign that there may be a problem. Some common causes of turbo noise (not to be confused with turbo damage) can be compressor wheel damage, split hoses, and over boosting.To make your car's exhaust louder, you can increase the exhaust sound by taking off the muffler. You can also remove the catalytic converter or install a cat-back exhaust. Consider putting on a performance muffler, cold air intake, turbocharger, straight pipe exhaust.
