3" Xpipe to 2.5" tail pipes?

I am in the same situation and am currently mocking up and building the exhaust system for my fish. I have the engine on a stand with the headers bolted on so I cen fab and weld the X steup before taking it to a muffler shop to get the rest done. The SB has TTI headers which I bought a nice stout flange/3" extension for and a X-pipe kit, also 3". Will go 3" back to 3" muffs and dump toward the ground right at the diff so the heat points out toward where the rear tires contact the ground. The first problem encountered is the X-pipe wants the headers to come out parallel and the TTIs angle inward in somewhat bt about 10 degrees each.

The joy of hot rodding...
