i have patronized them for over 15 years and they get a+ for courtesy, quality service, and good parts. another dealer just quoted me $650 and said that i needed a complete exhaust system. i took it to allstar and they said that i only needed a cataylitic converter and only charged me $150. the only exhaust place that i ever use!!! get there before 8am, as there are no appts. and they open at 9am: mon-fri.
