Duels out in front of rear wheels

Hello all. Like most of us money is gettin tight. My project is very close to being finally on the road. 67 Dart with headers 318 running duels to the back. This is what im trying to do. I have mufflers and straight pipe now to rear axle on hangers. I talked to the fellow whos going to certify the Dart. He told me as long as the exhaust comes out from the car (within reason) like in frt of rear wheels it would pass. So, Since i have the majority of the exhaust im woundering if any have done this. I can get pre bent 90s,45s and so on. Im not sure if you can just shorten up the straight pipe to mufflers and then bring them out? Were would you mount to? Im using hangers now at rear seat belt bolt area. Any pics or help in this matter is so appreciated you dont know. Trying to save and do all i can. Thanks in advance.
