Have they upped there game recently because ive had two different systems on two Audi S4 and both were crap, the fitment was crap and knocked on the rear diff, on one system the hanger snapped, and on the other the baffles started to rattle in the backbox.
Im running a Piper system on my Golf Gti and the quality is spot on and was no where near as expensive as the Milltek system.
