I need a new exhaust, the OEM sound just is not cutting it. I'm leaning toward the V&H bigshots, but have not commited to anything yet because I need more info. Like do I need a power commander or equililant? Can anyone vouce for discount cycle parts store, they've great prices but will I get the merchandise? I love the way my OEM pipes look and V&H big shot are similar. any help would be greatly appreciated
