Ok buddy I see what you mean
A bit hard to compare with such a different setup.
My logic: There are plenty of videos of Passat/CC 3.6's with suitcase delete and Magnaflow or Borla mufflers. They mostly sound good but maybe a bit harsh/raspy.
Relative to that, the mufflers I've picked are similar design (straight through with packing) and a big hot dog should just mellow/soften it a bit.
My pet hate... people that go to the effort of setting up, recording, editing and posting videos on Youtube but can't do the small service of saying what components are in their exhaust - it only takes a few words eg "2.5 inch dual pipe with 18" hotdog in middle and two Borla mufflers at back" - how hard is that
