I have a non-s line 2011 A5 2.0t coupe. I'm thinking of upgrading the exhaust to either an AWE touring or Jetex. Both come with an option for a quad tip setup. The AWE site says you have to replace the bumper and valance to get a quad setup with the non-s line. Jetex is silent on the issue. Anyone here have any experience with switching to a quad exhaust? Having to purchase a bumper and have it painted adds too much to the cost of just finding buying a valance (not cheap either, but at least it will not have to be painted and take of the bumper). Any help will be appreciated.
