The other day I heard a buddy's A4 with custom piping setup similar to the 16601 (except he had 14851 mufflers). I was curious which of the two sounds better. Listening to clips it seems like the 16601 is deeper and louder.
Any input is welcome. I know opinions on exhausts are subjective, however I'm just looking for which of the two is louder and/or deeper.
Thanks
