I'm theory if the car is running well and the cat material is of good enough quality, it shouldn't cause concern. Plenty of straight 6 cars have options for a single sports cats ie the below. I'll get the car tested and if whereby it won't pass, il swap out the system to OE spec. Few hours work on the drive once every 12 months is more than worth it for ART pipes.

Morning Nick, spot on for the super quick reply - its greatly appreciated.
Just called AF and spoke with Brian who lowered my renewal to a few quid below what Kim had quote so I've renewed. Speak in 2020, take care.
Just had a quote Kim on the team ref 7747, GREAT customer service and very friendly. Can you @CK@Chris Knott Insurance offer anything further, even 5% before choosing who to renew with?
Cheers
David
Do mapped cars with HFC's and rear O2 sensors switched off pass a lagit MOT for emissions? I understand the rear sensors don't effect the every day performance of the engine, however does it effect the emissions on test?
Ello n welkom, these I've found are great GT cars, power available at any rpm, comfortable, good view of the road with a great soundtrack from the VQ35
Have you checked the tyre pressures? Did the garage adjust them prior to adjustment. I can't seeing it being the cost to the garage as they hardly adjusted anything.
