fairladyz2013 Posted July 2, 2014 Share Posted July 2, 2014 Hello, Was wondering would it be 'better' to either decat or even get high flow cats for the zed before a remap/flash? Even though I might not run decats on all the time, due to noise (as find my cat-back noisy enough as it is). Many thanks for any answer given Quote Link to comment Share on other sites More sharing options...
GMballistic Posted July 2, 2014 Share Posted July 2, 2014 Depends ~ it is better to get all your breathing mods done before a remap as if you fit them afterwards you will need another remap to get the car running smoothly again & to see any gains. Personally if you think de-cats will be too loud then I wouldn't bother. If you can stretch to Berks HFC's or similar then that would be what I recommend as I love the sound my Berks give my Invidia system. Not to loud imo but then everyone's hearing is different. Also passed the MOT with no problems on my Zed which I hear isn't so easy with the de-cats. Quote Link to comment Share on other sites More sharing options...
