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).
As with the E46, I think the problem may be the stock exhaust is installed before the rear suspension subframe is put in and impossible to remove without dropping it? Not a big deal, IMO, unless you want to revert to stock when you sell it.
