Other Master Mufflers of Utah I believe are okay. Some are franchises, others are corporately owned. In 2005, I brought my life-time warranted, rusted out, muffler (purchased at the Sandy location) to be replaced at the downtown Salt Lake City shop. This location (the owner-manager) lied on the condition of my tail pipe describing a non-existent split of the seam and gave me two grossly inflated replacement part costs--whether custom built or shipped from out of state. Local auto parts stores quoted a replacement tail piece at a small fraction of his price. Furthermore when I asked for the upgrade cost to a MagFlow, again the price was triple what I would pay at a local auto parts store. I rejected the business of this shop and took the warrantee work to the Murray location which was fairly priced and like myself was unable to find the split seam in the tail pipe. I called the corporate office to complain only to be rebuffed with a protectionist posture for their downtown location.
Cons: Predator owner-manager
