hey man i have a 04 VHO and i put the original flowmaster 40 series turndowns on my truck and i must say it is pretty freakin loooud and it sounds really good! I don't know too much about exhausts I just went with what a friend suggested to me...so that's what I put on mine. But, if you want more power I have heard the magnaflow is wayyyy better, check out some of the other guy's trucks on here and a lot of em' have the magnaflow, I'm unsure of the sound but I heard it's good, good luck man
