I may be wrong, but I remember Twilight saying the Sable exhaust setup was a little bit longer from the cat back. This happened with another members car when he tried to mount the entire dual exhaust setup from a Sable onto his Taurus. When I mounted my duals, I only had the rear section which had been chopped off with a torch. I had to cut off my exhaust and weld on the new exhaust, rather than just unbolt the exhaust from one car and bolt it to mine.
Finding a Taurus would make things easier, but both will work.
Make sure you get the hanger for the right side. A left side hanger will work on the right, it is the same part.
Silicone lube makes taking the rubber hangers off REAL EASY.... otherwise they can be a PITA.
What part of Texas are you from?
