slk320 replacing resonator with a Borla ProXS dual in/out muffler
my secondary catalytic resonator needs to be replaced. thinking of removing both resonator and replace it with a borla dual in dual out muffler and completely remove everything else, pipes and rear muffler. then install tips pointing down or angled to the sides, since it doesn't look like i can do a dual muffler setup. i think the setup is more efficient and going to save a lot of weight from removing the rear muffler. hopeful for a deep rumble sound and no droning.
