Took the plunge and had 200 Cell Catalyst downpipes fitted. After fitting I was getting a horrid metallic rattle/resonance from the exhaust. After speaking to a few people the conclusion was that the stock PSE was causing resonance due to more flow.
The resolution for me was to have 9" resonators fitted to the stock PSE exhaust on the flex pipes (see start of video).
All audio from this video is 200 Cell high flow cat downpipes, 9" resonators on stock PSE flexi pipes and stock centre and rear Porsche sports exhaust.
No droning, around 10-20% louder with valves closed and around 30-40% louder with valves open. Sound is glorious.
