    Catalyst replacement on 3B

    Hello all,

    I am wondering is anyone running with catalyst replacements on a 3B coupe?
    What's the effect / result / opinion (bhp, torque, feeling)??

    I am thinking about having a set mounted.

    Thanks

      I have de-catted mine. It had a Scorpion cat-back exhaust, and removing the Cats certainly increased the noise! It also felt as if it freed up the top end a little so maybe a bit more power there. I haven't got a before and after rolling road output to prove that though. Well worth it just for the change in exhaust noise though!

              Yes it is legal in Holland. The car is old enough.

              Most important question; Did decatting bring out the fivecilinder sound??!!
