Does anyone pull with there truck with stacks. Does the exhaust go directly into the trailer while driving along?
If so I will not do it.
Do all stacks come up through the bed and THEN split into to stacks or did anyone do it with a split under the bed and then up through?
First question, yes unless you have very tall stacks or have a good width of a set of turn outs, you're gonna be gassing your trailer a bit. And if your tune smokes, its gonna stain the trailer.
Solution is to check out a couple of the other "stack" treads, there's a few trucks that run a couple of butterfly valves under the cab, and dump the exhaust that way when towing.
Second, yes all market kits will come up under the truck and then have the Y-pipe and spilt.
Hope this helps ya.
