Just had 200 cell crossover cats and the valved sports exhaust fitted, all by Top Gear. Had the work done at my local Powerflow dealer in Ipswich.
Over the moon with the result.
Valves closed = slightly quieter than PSE
Valves open = God of thunder mode.
Not driven it too much as I need to fit new connector pipes so that the tips line up correctly but so far it's very addictive. Quiet mode has no drone even at 70 mph and noisy mode is just mad.
Thanks Top Gear lovin the change and certainly a fantastic alternative to paying 3k for the porsche system.
Edit - Video Link added hope it works
