84 Bronco with Heddman hedders (long tube). I was laying out the route for my dual exhaust. When i did a temp bolt up of the collectors off the headders I noticed that I will either have to go under my tranny x-member (pipe will be hanging down under the frame-real ugly) or go over the x-member. Just wondering how other members dual's are...

Due to the output of the tcase, many run parallel tubes on passenger side and either swing back cross over the rear ds to a parallel muffler and exit opposite sides or run 2 mufflers in the stock location and exit next to each other. Remember, backpressure is a consideration. More tube on one creates a difference in the pressure.

I would suggest you not worry about the duals exiting opposite sides, but rather just step up the exhause pipe size and a high flow through muffler.

I dont know what year yours is, but I know that alot of people that have newer Broncos dont even run true duals.. Rather, they use a Y pipe and then split the pipe later in the truck where theres more room.. Just a thought..

it's a 84 bronco. But it's a all custom build. I'm using a NP200 t case. The OEM exhaust manifolds and pipe went above the tranny x-memeber if I remember correctly. I just installed my heddmans and the collectors are almost dead center of the tranny x-member with about a 3" gap between the two. I'm leaning towards going under because the bend will be real steep to go above.
