Exhaust systems

There are several companies making 3inch E body over the axle pipes but the problem comes in when you want just the over the axle pipe.

A few years back I ordered from Summit a over the axle pipe for B body cars. It was a Flowmaster pipe. You could try tti. I'm not sure if the sell singular parts to there exhaust systems. But I know there's will exit at the valance cut outs. I don't know about anybody else's though. IIRC, there might be an issue with rear sway bars & the tti pipes.
