See them on sale on their own website, around £2100 for 70mm Turbo back exhaust (resonated), nice looking system but I think I will stick with Milltek for £1075 and use the other £1025 on remap, Twintake/ITG/ and HPFP internals
Then again you could go BCS/Blueflame for £895 and get your RS4 valve fitted and have enough left for Full tank of Fuel and a good lunch
