Official db Reading Thread
So I downloaded the iPhone app: Decibels by David Bannach. I created this thread so that it serves as a guide for how loud aftermarket exhausts are. Since videos never do justice of how an exhaust sounds so I thought at least we can see how much louder they are than stock in further aiding the decision buying process. As a rule of thumb lets keep this app and keep the phone about a foot away from the exhaust. My results:
If anyone wants more revs or other readings let me know for the stock exhaust. I know this app may not be the most accurate but if we all use the same one and all get the readings from about a foot away from the exhaust we will have a good basis of how different exhausts are read. Everyone post!
