    For the people that fitted decats, did anyone else have an issue with running rich and extra petrol smell coming from exhaust afterwards. I realise I should have a remap after putting on the decat pipe, but need to purchase an oversize intercooler before I remap. Hoping that will happen soon (still got some xmas money squirrelled away).
    Cheers.

    You’ll get the smell of extra exhaust fumes as they aren’t being burnt off in the cat

    It's the one thing I miss about not having a decat, I love the smell

    You don’t need a remap or a bigger I/C but they would help so don’t be put off
    The cars in front are New MINI Scotland
