I am looking into changing the exhaust next week for something that will increase bhp/torque and was wondering what everyone else has done? I know about the milltek system increasing stock bhp/torque roughly by 7 and sounding pretty good aswell.
The other option I was thinking about was to have the exhaust made by a local,well experienced exhaust modifier who was saying that the stock design of having only the 1 backbox for both exhausts would not be good for the exiting gas flow suggesting there was potential for greater increase in bhp/torque if he was to make two separate back boxes?
