I had put some SuperTrapps slip-ons on my '17 Boss (after some cutting and grinding), but they are just a little too "putt-putt" for me, dont know any other words to describe it. Anyways, I am building a custom Softail and know that the Supertrapps will sound great on them, so I am looking for some kind of throaty exhaust in black. Can be 2 into 1 or not. I like a big pipe or pipes and they have to be straight. I like the sound of the Grenades but havent seen anyone put them on an M109. Any suggestions? Thanks,
