:stupid Thats what I did... single to dual is just cosmetic you won't gain anything and a single in single out routed to the back of the pasanger tire has less shit to rip off on the trails! :beermda said:Don't bother with the single to dual muffler. All that does is add pipe under your truck. There is no performance gain by adding the second tailpipe.
Just get a single in/out and route the pipe out your passenger side behind the tire.
