Plus I'm changing to solid state ignition.
My question is how to run the new exhausts. Should they run out the rear straight under the bumper? Or along the running boards and dump out the sides in front of the rear tires? Or should they dump out the side behind the rear tires?
Oh, and I'm not interested in cab stacks, although I know that is an option too.
Thanks for your opinions.
Seek results, not perfection. Remember this is a truck, not a Rolex watch.

My pipes have 6 inch chrome tips welded to the ends. This will give you an idea of what duals look like sticking straight out under the bumper.. Exhaust Pics

I think on the sides you would hear more which can be good or bad depending on your mufflers and your point of view.

The six has a rather strong "pop" in the pipes and the longer the pipe the more mellow the sound becomes. You don't need large diameter pipes as they'll make 'em sound harsh as well. 2" work just great. Put'em out the back and they'll put a smile on your face. | | |
