i ve been told if i fit milltek cat / downpipe on to my existing cat back on my S3 with out getting stage 2+ map it will bring on engine fault light !! any one heard /experienced this ????????????? sorry resonated is really quiet more so than oem imo
If you want a bit of noise but want to keep it refined, there is a butterfly valve in the standard exhaust which is closed at low revs.
This is air controlled and can be simply modified by pulling off the air lead and securing the valve open. There is no harm in this and will not cause any issues or bring up any lights on the dash or on vagcom - just means you have a nicer note all the time but still keep the stock system
I'd personally go for non-res, Matt's res is far too quiet for me
Yeah i agree nate id go for the non res i like a bit of low grunt in an exaust ...
I want all the performance gains without the extra noise. Why can't I have that?
To be honest this is what I was after - was pretty nervous about fitting a Resonated Milltek, but god knows why - in the cabin I can't say I notice any difference - it's only when I'm outside the car or tunnel blasting with the windows open that I notice the difference.
