Review on Enhanced Performance Muffler: Walker Exhaust SoundFX 18280 by John Kachinosky

I bought two of these for my Ford Galaxie 66 with a 352 engine. This model number is shown as a stock replacement. I'm tired of the noise and hum from two double-glazed windows. The mufflers fit very well, are fairly quiet and seem to be good overall. The only thing I complain about is that when I press to the ground and the 4th kick kicks in, they do something like a high-pitched whine, which is pretty annoying; I do not like it at all. So I would recommend it to people who rarely step on the accelerator hard. Otherwise you can choose another product.
