I think I posted in wrong section...! Lack of replies meant I thought Id dig a bit deeper before taking the plunge..
I have a friend who works in a motorsport shop; they do parts for Audi, VW, Porsche... He's raced and has been in and around motorsport most of his life - I didnt ask his advice before because I thought he was just Porsche / high end stuff.
He says that inside the industry there are major problems with Milltek and that there are major quality problems with Milltek exhausts cracking? I dont know never used one, but he says that at the beginning of the year they started moving production overseas to china and the quality has just fallen off a cliff??? Im going to do a bit more research but for now I'm steering clear of Milltek - what other options are there??
