Does anyone know the flow rate of the stock front boxy cat on the Aveo/Barina E-TECH II 16V engine ?
As part of my 'get a move on' campaign I'm thinking of replacing the stocky cat with a high flow metalcat but as I have no idea what the stocky OE one cat flows at I'm not sure whether I'll just be wasting my missbegotten gains or not.
Stock cat on E-TECH II 16V ?
