Stamped mounting flange

Our restoration quality muffler has the correct dimensions and baffling, including a deflector, which provides the correct look and sound. The flange is stamped steel not a piece of sheet metal like the competition. Additionally, our muffler has the same amount of steel as the factory mufflers, weighing 3.75 lbs. Many other companies sell a light weight muffler, which is loud and not as durable and need to be replaced more often.
