DAWG, i'm just curious about something. Did you happen to use the tapered OEM exhaust gaskets when you installed your pipes? I had exactly that problem. I was told to use the SE flat gaskets and the whole rig went together with much greater ease and no brake lever rattle. just a thought.
A little advise, have the Saab towed far, far away!
Borrowed a buddy's truck and tow dolly, pushed the damned and got it rolling down the drive and up onto the dolly. Towed it to the next town over where there is a local old time Saab guy. Sold him the damn thing for parts to get up the cash to help pay for the truck.
