Our options for exhaust are limited. on eisenhaus website the race exhaust looks nice and im sure sounds nice but iam not not looking into sound change, my priority is gains in HP and TQ. I dont know of any before and after exhaust data. After reviewing the pics from eisenhaus i though of replacing the stock mufflers with a borla or magnaflow race muffler and doing a before and after dyno. any thoughts or feedback?
