Terence Posted January 18, 2023 Share Posted January 18, 2023 Hi I’m looking to replace my test pipes for hfc which will pass the MOT. I had berks fitted but only lasted one year . Im running 418whp Any ideas as the MOT is due in March Cheers Terry Quote Link to comment Share on other sites More sharing options...
RickyZ Posted January 18, 2023 Share Posted January 18, 2023 Used to run Kinetix HFCs that passed MOT... My car was not supercharged though, so imagine that would make a difference. Quote Link to comment Share on other sites More sharing options...

The Bounty Bar Kid Posted January 20, 2023 Share Posted January 20, 2023 Have they warmed up the cats? The Berks need some heat to work properly. Don't let them test cold. Quote Link to comment Share on other sites More sharing options...
Ekona Posted January 20, 2023 Share Posted January 20, 2023 If it’s just for the MOT, pop some OEM ones on then put your test pipes back afterwards? Quote Link to comment Share on other sites More sharing options...
Jack94 Posted January 20, 2023 Share Posted January 20, 2023 Or find a "friendly" MOT tester. I thought the general concensus was that HFCs don't tend to last very long on FI zeds. Quote Link to comment Share on other sites More sharing options...
Coz@TORQEN Posted January 20, 2023 Share Posted January 20, 2023 As Jack mentioned above, cats are not meant to be used on FI Z's as the temperature burns the cat material inside. Go for a decent set of resonated test pipes and find a 'friendly' tester if you can. Quote Link to comment Share on other sites More sharing options...
