Mini tub exhaust

Alright guy's and gal's, I installed mini tubs and brought my springs inboard last year. I run 3" to super 40 Flowmasters, and dump them in front of rear axle. Just happened to be sitting behind it at a car show today, and realized how far offset the gas tank is. My question is, how the hell do you run exhaust out the back if I ever wanted to, never realized how close the pass side spring is to the gas tank? Is it even possible with stock tank, or would I need a fuel cell? Hate to put a cell in car, so how have you guys done it??

Thanks Jeff
