Exhaust idea.
Hi guys, This may be a silly question or idea, but after being at a mates place, and sussing out his wrx sti, he told me about his exhaust, he has a 3inch dump to a 3 inch cat exhaust into a 2.5 inch axel back into a 3 inch muffler back and going off his dyno results, he netted .1awkw in total power..
