This might sound either logical or illogical, but would replacing the standard restrictive exhaust (from secondary cats back) actually improve fuel economy? Reasoning behind this thought is once the stupidly restrictive crimped t-piece (where the pipework splits to the two rear boxes) is replaced with a free-r flowing, angled, full diameter v-split and to different boxes, the air flow would improve this reducing a back log of air flow and in theory reducing workload on engine especially lower rev/higher gear/uphill pull?
