Hi, I’m back with my exhaust! I got in touch with FOX again after my caring workshop told me that FOX also offer very good financing and that the 70 mm systems, which are actually intended for the S2 Quattro, should be combined with an adapted chip up to 10 HP, with a large 200 Zeller KAT even 15-20 HP. This makes the thing more interesting now than a cheap solution. FOX have confirmed on my request However, I have to change the pipe guide from my current exhaust at the front by KAT and VSD for the S2 version, because this has 2 cat ́s and accordingly also a double pipe guide with a different way. But that should not be the problem. And my TÜVler has always registered everything I wanted if I only threatened that I would have to register my all modifications elsewhere. But I am irritated by the statements of some vacuum cleaner drivers, who had significantly less torque and an unstable idleness with S2 systems or generally systems with very little backlog down. That would be fatal. Wa s brings me above all more power, if he runs down in everyday life no more. What do you think about it? If no one knows, I will probably think for the test on the example CU and post not forget Markus
