This is my second exhaust system in 21 months. The muffler is fine. The weal spot is the flex pipe that connects to the muffler but it's all a single unit. The part itself is $380, plus tax, installation not included! Anyone have cheaper alternatives? Anyone else have this problem of frequent exhaust system wear? Do I drive her too hard? I have been known to go top speed (90 mph) for stretches whenever possible.
