I suggested he sell the catted dp on ebay or nasioc because catted dp can normally get some decent money because well high flow cats are expensive.
those little turbos create enough backpressure as is adding a cat on the car does not really help much. that is why i suggested he get rid of it. if you have ever seen the stock tdo4 its is really small.
