I would look at upgrading the entire exhaust from that middle clamp back. Chances are if the middle muffler is bad, the rest of the exhaust from there back is too. Both my middle and rear mufflers were the original, and totally rusted. It, suprisingly, cost less to go with the Saab sport exhaust then the OE system. IMO, the sport exhaust is the best option...and it sounds great too!
Hi, I just ordered a SAAB sport exhaust from an ebay seller. The price was $320.00. The seller was general sales saab cadilac in PA. The total with shipping and a round tip was $379.59. They said it was complete with clamps. I did a search for Saab exhaust. Good luck.
Update: I ordered this exhaust on Monday and received it on Wednesday.
Now to put it on.
