tonman83 Posted December 11, 2016 Share Posted December 11, 2016 (edited) HI All, I’m running a 2005 350z with Japspeed 350z de-cats , Cobra y piece and Scorpion exhaust. I bought the car in May, and it was made clear to me that there were no cats. It’s coming up to MOT time, and I have been considering buying some cats to put into the car. I have the following questions: Is it right that if the car is running well, it might not need the cat to pass the emissions test? If it fails and I decide to buy some, are there any that you would recommend, I can see there are a few high flow options at Berk Tech and Torqen, but there are a lot of options! How do I know which one to buy?! And will these pass the emissions? How and where can buy stock ones? Thanks Edited December 11, 2016 by tonman83 Quote Link to comment Share on other sites More sharing options...
Jetpilot Posted December 11, 2016 Share Posted December 11, 2016 (edited) If it has no cats its an instant fail (cats must be present if they were fitted as std), personally if your happy with decats i would just buy some std cats and swap them back in come mot time as hfc's are not guaranteed to pass.

KyleR Posted December 11, 2016 Share Posted December 11, 2016 How friendly is your tester? Many people have passed without cats due to not using a grumpy tester. Quote Link to comment Share on other sites More sharing options...
tonman83 Posted December 16, 2016 Author Share Posted December 16, 2016 I will explore that KyleR as a I have a few garages I use. I'll post on here how it goes! Zmanalex, please let me know if you acquire any! Thanks Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted December 16, 2016 Share Posted December 16, 2016 I wouldnt highlight the fact is has no cats and see if it passes. If it does then great, if not then you know to find somewhere friendly or retrofit some. Quote Link to comment Share on other sites More sharing options...
