Tassie, if you are looking for more flow from the exhaust then combined with the chip you are running then we are talking about a system that runs from the turbo back. Hence new high flow cat plus the extra bits and pieces. Might be worth while taking to someone in the know down there, ( exhaust specialists ) as the general concensus seems to vary somewhat even on this site. I have found with mine and the chip that the torque flattened out somewhat straight off idle and then there was a noticeable improvement in the mid - range. I then had the tune of my chip retuned via laptop to regain and improve the bottom end torque. Silver actually tested my chip and was very impressed with the bottom to mid range capabilities of his vehicle when fitted. Silver also has custom 3" from turbo back...........There is a benefit but I must ask the question, At what cost?

Mr Silver has a new project at the moment. He has started restoration on his Charger which he has owned for some twenty years and judging by the quality of his work then this will be one god almighty vehicle when finished.......
