    As the title suggest's, I want to decat my 323i and was wondering if there is an off the shelf one i can buy that anyone knows about.

    Only reason I am wanting to do this is because the cat is rattling/vibrating at 3k rpm plus and its driving me up the wall but its still passing emmisions tests so i'm reluctant to fit a new one.

    If there isnt one out there i will just get one made up i think. Also, if i decat it are there any problems i need to be aware of... I know power gain will be nominal and it probably wont pass an MOT.

    Maybe its just easier to fit a new cat
    All advice welcome.
    Thanks in advance.

    you could always buy a second hand cat and gut it and make your own decat?

    I had my 325i decatted as it is pre cat test. TBH it made a big difference, the car is much more eager to pull from low revs..
    The only problem is that you wont pass an emissions test...

    i think the best thing to do would be to keep a spare exhaust just for MOT.
    There are only two products required to make the universe work properly: Duct tape and WD40. 


    If it moves (and it shouldn't): duct tape. 
If it doesn’t move (and it should): WD40.

    Everything else is just stuff.

    Why not keep the 323 exhaust with cat for mot time and rest of the year fit a 325i or 328i twin pipe system. Much more free flowin than 323i type

    328's have 2 cats. Find your local powerflow fitter and they will either sell you very expensive free flowing sports cats or make you straight through pipes for a reasonable price.
