    Been thinking of de-catting my 325ci, as a temporary thing - i.e. being able to bolt on and off when ever needed.

    In terms of doing the job, I'm guessing its more than simply removing the outer two cats underneath the car. I assume there is going to be some kind of tinkering around with various sensors ect, is this the case?

    Cheers

    If you are doing this to gain extra power you will be much better of remapping the car

    Indeed bwchiptune, I will be getting a re-map after I have the engine/exhaust mods complete. I currently have a pipercross viper induction kit and a custom backbox from infinity exhaust in Bristol (top guys by the way).

    Main reason to remove the cats, bit more noise and an extra couple more bhp that wouldn't be there otherwise. Also, I'm thinking if I get the re-map before removing the cats, it's going to be set around 'x' amount of exhaust flow - which I guess will be increased with the cats removed, making the re-map less effective.

    Do you know if there are any sensors/fuses ect. to fiddle about with when removing the cats?
