I like the idea of using SEAT parts if I can and have been contemplating this mod for a while - IH786 thanks fo the guide However, although not to difficult to replace my present system with the FR, I have found this stainless back box http://www.seat.com/com/generator/su/com/ibiza/site/accessories/sport/Sporty-exhaust-pipe/Main.html - what's your thoughts on this, which is approx £230 including sleeve supply only And yes I know I could get the millteck, but your thoughts would be appreciated.
