Well after 9 months and about 800 miles since completion I want to buy an assortment of sidepipe mufflers. My kit supplied mufflers sound great at idle and wot but living with them on long ( 1 hr plus) road trips requires noise canceling head phones. Wouldnt it be cool if someone had a sidepipe muffler with variable sound levels using electric baffle valves. My ears ring like after a WHO concert when Im at a steady 2200 rpm on the highway withoutear protection for more than 45 minutes. I guess Im getting old
