Audi 1.8 T

just had the car mapped and lowered and the cars performance is night and day with over 40% more torque.

Looking at now either buying a remote bi-pass exhaust valve and install after the cat, or could just go with removing the rear twin back boxes.

Question though, does the car drone without the back box baffles? I have a 6 hour commute so don't want to make it unbearable. !

thanks in advance !
