I got mine at the Meineke on Holland Road near Lynnhaven. Originally I had them put on a Vortex muffler, made by Cherry Bomb. The muffler sounded great, but developed a rattle in it. Unfortunately, once the muffler warmed up, the rattle would go away, but it drove me crazy! Finally it got bad enough that the fuys in the shop could hear it, and discovered that one of the baffle was broken. They replaced the muffler with a flowmaster- at no extra charge. Now my truck sounds terrific. I'd go back there again. I also had them do my inspection last year- got out of there in about twenty minutes!
