All right, I know there has been a lot of talk about exhaust systems and which is better. Right now Im looking at either the dmc duals or the hmf bill balance carbon fiber full system. There isnt too much of a difference in price. 560 for the hmf 700 for the dmc. Although I dont have a pc3 eiecther so I need to purchase that as well. So after everything is said and done the hmf will be around 900 and the duals a little more. But on ebay they have a package deal for the duals. I just need some feedback on which one produces more power, the db levels, and personal preferences. Any help would be great.
