This shop in Glendale is very nice with a comfortable waiting room and most of all the work they do is impressive. I was bit reluctant initially taking my BMW for an upgraded exhaust system, but the gentleman named Lucas was extremely knowledgeable, polite and professional. he took the time to explain all the available options answered all my questions which helped ease my initial reservations with changing the system.
i am glad i went with them because they truly do great work.. They are also affordable and give you lifetime warranty on their work.
I am only giving them 5 stars because that's the most you can give. two thumbs up!!
