Umster Posted March 25, 2019 Share Posted March 25, 2019 They are aftermarket high flow cats, which will improve power output from the engine, increase noise (volume and tone), and are of fairly good quality. They aren't premium and they will mean you need to find a friendly MOT tester or remember to have a spirited drive to get the cats warm and working optimally for the MOT. You can always go back to stock or try another set of aftermarket cats. There will be plenty of buyers on this forum if you decide to sell. Make sure you ask the owner how long they've been on and what happened to the old pair. Ask if the car has been tuned and sensors disabled. Hope this helps.

Mike k-g Posted March 25, 2019 Author Share Posted March 25, 2019 Thanks Umster for your reply ...unfortunately the car is at a Garage guess they wont know much about it. Quote Link to comment Share on other sites More sharing options...
Umster Posted March 25, 2019 Share Posted March 25, 2019 Works to your advantage still, by law, you get a 3 month warranty. Any issues, throw a wobbly and demand your consumer rights. Make sure they MOT it before they sell it to you, makes your first year of ownership easier and if it fails on emissions then get them to source and fit some stock cats for you. Ask them for any paperwork they have, there will always be the name of a previous owner and if you're lucky they might have been on one of the many forums. Good luck and hopefully welcome to the owners club! Quote Link to comment Share on other sites More sharing options...

Andy_Muxlow Posted March 25, 2019 Share Posted March 25, 2019 I have them on my 370z and no issues at all with them so far. They were a straight swap with good fitment also. Quote Link to comment Share on other sites More sharing options...
