So I was looking under my flex and it seems to have dual exhaust all the way back except for the center muffler. In interest of $costs$ I was wondering if removing the center muffler for just two straight pipes and leaving the two resonators at the back on if that would be quiet enough? The center muffler is after the two independent cats and after any O2 sensors ect, the center muffler is right after an xpipe which I would leave in place.
