AUDI TT CUSTOM VALVED QUAD EXHAUST SYSTEM... SOUNDS INSANE!!!🔥 

#auditt #exhaust #fastcars
Today is the day Kirbster, my stage 3 Audi TT running 450BHP gets the upgrade I've been dreaming of for a long time! A valved quad exit exhaust system with switchable modes from Overkill Performance in Milton Keynes.
To add icing to the cake I get the guys to upgrade the rear diffuser to a stunning carbon fibre piece from AP.
TODAY IS GOING TO BE GREAT!!!
