I needed a new flex tube put on my 2000 Toyota Camry. The Toyota dealer gave me an absurd quote-- close to $1500-- and recommended that I check out Red's Muffler Shop for a reputable fix from an independent garage. The people at Red's were very friendly and walked me through exactly what had gone wrong with my car. The real kicker, however, was the price: about $200; or, 1/7 of what the dealer wanted to charge.
I don't drive very often, but after a few months and a few hundred miles on the new flex tube, everything is still running well on my car. I would go back to Red's again.
Update: it's been two years and about 5K miles and the car is still going strong.
