    As title.

    Does the biturbo petrol 2.7t have just 2 x cats or 4 cats (2x pre cats, 2 x extra cats further along exhaust)?

    If so, can I delete the pre-cats and still pass emissions.

    Or

    Race cats instead?

    Thanks carl

    2 pre cats and two main cats...Folk upgrade to sports cats if they want more performance and still pass the emissions. Speak to MRC...
