These muffs are quality! Well polished, welded in well, and have provided the sound I was after. Note, if you're looking for total quiet like your daily driving family car, these are NOT what you're looking for. But if you're looking for a good deep sound that says muscle, you want these Kooks muffs! Note, these are installed on a Factory Five Cobra Roadster with a 347 CID Small Block Ford with AFR heads and a pretty racy roller cam in it that makes about 525 HP @ 7,500 RPM. So these may be a little louder on my application that a V8 that is more tame. All expectations met or exceeded! more
