Someday I would like to receive an Aires muffler without at least one dent in it = 7 in a row in the last three years. The box is always undamaged, so I have to believe the mufflers were packed from the manufacturer with the dents already in place. Only the stainless steel muffler I ordered earlier this year was undamaged. I installed a regular Aires muffler yesterday that was ordered on Monday. One dent. SURPRISE!!!
Not to sound complaining, but we also had to place a drive shaft inside the pipe portion that mates to the exhaust manifold and bend this portion forward. The angle was wrong and wouldn't seat properly against the exhaust manifold flange, no matter what angle we titled the muffler. Bending that portion of the pipe forward brought the alignment into place. The car's frame is not sagging, the rear motor mounts are original style with good rubber, and the hand crank fits into the pulley ratchet nut. The exhaust manifold is brand new. So, everything in in alignment - except the Aires pipe.
Don't get me wrong: The Aires muffler is a good product and I'm glad they are being made to replace those worthless cheap-^ssed Midas garbage mufflers that we have been obliged to buy until the late 1990's. But I would like to see a little better quality control from the manufacturer. Perhaps occasional spot checks after packing to find out who is putting dents in the muffler portion? This many dents over the years is not co-incidental. Someone at Aires doesn't like his job so he takes it out on the mufflers. Or at least, the ones I have bought. Anyone else receiving dented Aires mufflers? Or am I being targeted?

O.K. Enough grousing. I like the muffler. I just question the quality control in the last couple years.
