Want an a/mkt exhaust with low tones & some volume - suggestions?

[MillBilly]

Hello everyone, first time posting. I just got my Spyder RT-L a few months ago and got all my mods installed. I have a Road King Classic. I just took my wife for her first ride on the Spyder. One of her responses to the ride was "I want rumble" lol, I told her that wasn't possible, but I was already looking into what I could do to make it sound as aggressive and throaty as possible. I've already done the cat delete pipe, that gave me a little volume. I was looking at the Two Brothers Exhaust, but I'm hesitant to pull the trigger not knowing if it's the best fit for what I'm looking for. I want to get the lowest tones with some volume. Any suggestions or input would be greatly appreciated.
