Pie cuts to offset a resonator

I’m going to be adding Vibrant Ultra Quiet resonators (#1141) to my car and on one side it would be about 1” from the side of the transmission. For heat purposes, I think it should be a little farther away than that. I’d like to make it about 2”.
But I don’t have much length between the bottom of the down pipe from the engine and transmission crossmember so I can’t use regular offset pipes from Walker, etc, so I’m thinking of using pie cut sections of tubing.
So my question is, does anyone know how much offset I could get in 2"?  
The body length of the resonator is 9.75” OA length is 13.75” which means there is a 2” inlet/outlet tube on each end. The inlet/outlet diameters are 2.5”.
I'm trying to figure out if I can move the inlet/outlets over 1” in as close to the original OA length as possible.

The exhaust on the Abomination is closer than 1" to the transmission and the transmission tunnel. Any reason to not run heat shields?

These are held in place by welding a bolt to the exhaust and using nuts to space the shield about 3/8 off the exhaust tube and nuts to hold the shields in place. Even with rotary power, they made a significant improvement on trans tunnel temps after installation. No more 2nd degree burns on passengers' legs.
