    Is that the one that fits the stock system. You just remove the twin cats and bolt this decat on? I think they're pretty good for that reason.

    Decat is definitely beneficial over a sportscat, but you need a friendly MOT guy come mot time! Mine release 10bhp a few weeks back.

    I saw someone post the other day asking about back pressure issues with a decat but I've never heard of that before. Removing the restriction of a cat will help.

    If you have a post cat lambda sensor then it will throw up the engine light if you've not had it disabled in your map.

    Not noticed it to be louder to be honest, mine is still the standard downpipe and standard cat back exhaust system.

    Mine didn't have the post cat sensor, so stuck a bung in the hole, and no EML light!
