seriously thinking putting Milltek on my B8 S4
Wondering has anyone did the same on their B8 S4? Did you go for the twin pipe or the oval? If I went for race version does it mean it is louder and will i fail my MOT in the future? Are you happy with the outcome? does it sound as good as the AMGs? Sorry for bombarding all the questions? Just thought if I am going to spend circa £1800, i just want to make sure I've made the right choice.
Thank you so much in advance. Looking forward to hearing your views
