Do all exhausts require hacking stock muffler?
As the title says, do all of the current aftermarket mufflers require that the stock muffler be hacked off the pipes? I am primarily interested in the Eisenmann, SS or Remus mufflers. Do these particular ones require the hack? From my search it seems the Remus does and I believe the Eisenmann as well. Would love to get some info on this, though I will probably wait until AA and Rogue release their mufflers before purchasing any (hopefully this will cause pricing to be more realistic as the Eisenmann and SS are at this point overpriced imho).
