Has anyone installed the Big City Thunder baffles in their Vance & Hines slipon mufflers? If so, how do they sound compared to the stock baffles that came with the mufflers? I am not so much into loud volume in my exhaust but I am really after a deep, low rumble. The stock V&H mufflers with baffles are pretty close to the sound I wanted but if I could get a little deeper tone it would be even better.
