Ace has installed several Magnaflow Cat-back systems on my Ford F150s and Explorers. Outstanding job, fast, quality installation!
In fact, when Ford Senior Engineers (from Detroit) asked what type of exhaust system I had installed on one of my Explorers and who installed, they were so impressed by 1) the Magnaflow system and 2) installation that they requested I mention both Magnaflow and Ace Muffler (Westminster!) on a video interview, to be used later for a Ford endorsement.
I have referred everyone (all the way from South to North County) to Ace (Westminster) that has asked for an exhaust shop referral. Again, great work Ace and truly a pleasure working with someone you trust.
