My car is NA. I disconnected the muffler to see how that would affect the exhaust note. Being that the car has EL headers, a lot of the boxer rumble is lost but not entirely. Essentially what I will be doing is a muffler delete and replacing it with a straight pipe exiting at the back of the car instead of just after the rear axle.
On a side note though, since you upgraded your dp, did you reflash your ECU to stage 2?
