Need a little help, got me some brand spanking new tarmac sportz HFC's, fitted them and then took the car in for an MOT and its failed on the emissions massively (this is with me pre warming and with the tester taking the car out himself) so my major questions are simple. How hot do you need to get these things? Tarmac Sportz claim they will pass cold on the website but i was dubious of that. Is it a case of a 30minute spirited drive, or closer to 2 hours? or are there other things i can do to bring the emissions down? going back to oem cats isnt an option as car didnt have any when purchased.

Hey chaps. I have recently stripped down and refurbished the 5th bow motor with fresh carbon brushes after it got stuck open and just have a question. Do I need to reset the roof in any way or is it a case of reinstall the motor, hit the button and enjoy the British summer and the v6 noises? Cheers!
