Fabbing a transmission crossmember

Now that it's all done, there's really only one thing I'd do different. Since this is a 6 cylinder, all the exhaust goes down the drivers side. There's space there to tuck the crossmember higher, so the exhaust could go below without having to sit quite so low. It would've been more work, but would've ended up better in the end. It's definitely not big enough that I'm going to redo it, it'll be fine. 

You have the skill set, could go larger pipe from the engine and oval it for the cross member and reduce right after. 

Or do the Jeep thing with the split header and keep it 2 pipes, the collector after the crossmember, or a dual exhaust I6.

Just more time, money and work!
