Been interested in the Milltek Cat bypass pipes, but got warned off by the fact they are marked up as "not for road use". Someone on here has posted that Audi Tech's are refusing to work on their cars if they see them. I suppose there may be other issues of legality if they are marked up this way and you were involved in a serious RTA and the cop's inspected your car.
Because of this i looked around for an alternative and found these by Supersprint:-
Supersprint Front Pipes Kit Left + Right - (Replaces the Main Cat), Audi A3 Sportback 8P , Sportback 2.5 TFSI 340Hp 2011 On Road Use
Does anyone have any experiances of these?
The important thing is the are advertised as "for road use".
