not too bad

November 18, 2011

Product is good quality. works best if applied over dynamated surface. Noise reduction is mild, but noticable. Dont expect it to sound like a lincoln, but it helps with higher frequency reduction. Applies easily and sticks like crazy. Covers pretty large area, most hoods will be fine. kinda expensive for what it is, but overall happy.

Much Less Engine Noise

April 4, 2010

Covered my bare Amigo hood with a bit to spare. Attractive product and easy to work with. Looks great and engine noise is much less. It is much quieter in the cab and my stereo sounds even better. It really seems to reduce the high frequency sounds from the engine. All the valve noise is gone. $50 well spent!
