Mike's Muffler - 12222 Garvey Ave., El Monte, CA - 626.443.5139
I recently had the BMW performance exhaust installed by another shop. It sounded great but to my horror, it sat too low, one side wasn't centered, and the tips stuck out way too far. One visit to Mike's and everything was fixed and I got my stock tips put back on. I don't think this exhaust sat so perfectly even from the factory. They were very professional and checked in with me before tacking on the tips. Well worth the drive from west la, dealing with non moving traffic and all. Two thumbs up for these guys and the hard work they do for a very reasonable price.
