Just wanted to chime in on this thread about "Mr. Muffler". I've had this same guy do a whole bunch of different work for me, about 5 mufflers and some custom welds for parts that had to be fabricated. He is indeed a master craftsman, who puts a lot of effort into his work. When working with higher quality materials, stainless steel for instance, he is very careful not to scratch anything and even buffs it all out once its installed. I highly recommend this guy's welding, and if you have some custom work, can speak Chinese (or have a friend to translate), he will try his best for you at a very reasonable price.
