Was at the track 2 weeks ago. Every ladder bar car with exhaust out the side & in front of the rear tire I seen you could see everything. Mufflers etc. Only way to really tuck it up there is to have the front ladder bar cross member buried up in the car. Mine will be somewhat like that because I want the cars stance to be as low as possible. It may end up with enough room. Just don't know yet. I will see what I got to work with after it's under the car.
There is so much room on the picture you posted with the 4 link that an exhaust could be brought up an over that whole set up. To the rear of the car if you wanted.
