I currently have a single in/single out FM super 44 and love it. I recently notcie the piping, a foot before the muffler, is 2 direct pipes.
Would I get better performance/sound/back pressure by swapping in a dual in/dual out(single out, I have it dumped so will the # of outs improve this as well?)
A buddy of mine recommended getting a small x-pipe before the muffler and getting a dual in/dual out
