I am very happy with the exhaust. there is a deffinate "sporty" sound to it now when its booted. With the windows open it sounds great too...for a diesel. Definately go cat baqck, straight though with no boxes at all....yours will be lounder than mine as you have the DPF delete. Doesn't the oild in the ITG filter clogg up the Maf or summit ??? I keep wanting to change my air filter as I have to clean out the box once per month !!!
