Review on Dynomax 22572 Heavy Duty Muffler by Lloyd Edwards

This was the correct muffler for my F250 Super Duty diesel engine. A good compromise between sound insulation and no performance-reducing back pressure. It still has that nice diesel rasp, but at a lower volume. The block is large, about twice the size of the one it replaced, so check your measurements first. I expect this to be long lasting, but if not I'll update this review.
