Richf Posted January 9, 2016 Posted January 9, 2016 No , they will not meet the emissions required for the mot , if it is done correctly, its pretty clear, some hfc struggle unless they are really hot Quote
Jetpilot Posted January 9, 2016 Posted January 9, 2016 The op's question was will they pass, not will they keep anyone up at night. My berks passed as do quite a few Quote
zippypooz Posted January 9, 2016 Author Posted January 9, 2016 I suppose if any cat can, the motordyne cat can!!...hopefully. If not i'll do as Jetpilot does and change each year! Quote
Kev T Posted January 9, 2016 Posted January 9, 2016 I have the Art decats mated to the XYZ HFC and the 370 has passed mot every year. ( so far) 1 Quote

Rich260 Posted January 9, 2016 Posted January 9, 2016 I run Berks de cats with XYZ pipe with sports cat, past mot for the last 4 years with no issues. 1 Quote

88 Zed Posted January 10, 2016 Posted January 10, 2016 Obviously it wouldn't pass the emissions test with de-cats fitted but if by some magic it did, and the de cats look like sports cats or at least thicker than the rest of the pipe work than there is no way to tell whats inside. Obviously if its just been cut out and a piece of straight pipe welded in then its a fail. Good luck! Sent from my iPhone using Tapatalk 1 Quote
zippypooz Posted January 10, 2016 Author Posted January 10, 2016 I'll probably end up buying the XYZ HFC pipe!!...and see what happens!! Quote

HaydnH Posted January 11, 2016 Posted January 11, 2016 [quote name='zippypooz' timestamp='1452366485' post='1572208'] Id be interested to know if anyone has fitted de cats and an XYZ HFC pipe and passed a legit MOT. [/quote] I had the ARTs+XYZ/HFC combo on my HR and it passed, sometimes it required a second run to to warm up but that's not really an issue. I accidentally went decatted when I got a custom titanium exhaust made and they did it from the decats back rather than the XYZ/HFC pipe back... it's a pain to have to go to a friendly MOT tester to be honest, but not enough for me to bother replacing the ARTs.

[/quote]ahhhh sounds promising then!! Did you notice any drivability improvement with this combo? Quote

Did you notice any drivability improvement with this combo? [/quote] Hard to tell, I also had an Uprev done at the same time so there was lots of difference, just not completely due to the exhaust. Great combo though. I actually miss my XYZ pipe even if I do have a custom titanium bit there now. 1 Quote
zippypooz Posted January 11, 2016 Author Posted January 11, 2016 I think an uprev may be worth doing after the Art pipes and xyz are fitted!...although ive heard conflicting stories on its results but im thinking art pipes and xyz may do the trick with uprev. Ive done all the other gubbins. Quote

[/quote] Yeah, moving the cat further down the exhaust chain apparently has an effect on torque after an uprev.... if I remember from what Mark@abbey was telling me ages ago. Quote

zippypooz Posted January 13, 2016 Author Posted January 13, 2016 Ahhh ok. Had my Art pipes fitted today. Sounds nice!! Quote
RD - Forged GT4 Posted January 13, 2016 Posted January 13, 2016 Not that I've done it but you could always just leave the standard cats on for mot then whip them off and put some decats on. quick 15 min job Quote
