One slim possibility might be to check with a diesel/heavy truck repair shop. Though they probably can't bend it, they may be able to point you to a shop that can. Many truck exhausts are fabbed out of elbows, shorts, and flex, so it's probably not much of a shot, but it's all I got for you locally.
yeah i thought about piecing it together but its a 4x4 so the transfer case/crossmember area is pretty tight. i hope someone knows but if i dont get anything on here ill probably have to see where the big trucks or school busses have work done.
Most (if not all) exhaust tubing benders on the market only bend up to 3''. Anything larger its cut and weld. Aftermarket companies use bazilllion dollar mandrel benders to make their stuff.
Besides, if you have tight clearances, you need to use small mandrel bends. Compression benders (exhaust) use pretty large radius'. My 3'' dies are 8 or 9'' rad. Plus, with that type bending you cannot get the bends close together.....which creates more problems.
