Interesting to see people's opinions. Looking for an exhaust too. Pretty undecided!
I have a BCS Powervalve on my Edition 30, hence why I'm very keen to go back with them as Nige produces some epic equipment. He advised me to go with the WRC Valved system since the GPF kills it so much that it's the only one that will give it a bit more oompf.
Their full systems work off turbo pressure so when cold start or just idling about it's quiet and when you put the foot down the valves open and you get the noise.
There's plenty of system and videos of mk7's on his instagram and youtube that don't have a GPF filter, if you're lucky enough not to have one.
There's a reason why I'm not going Milltek or Remus.
