    As im due to get a bigger turbo fitted to my s3 getting around 350bhp, APS have told me i will need a new cat, because my milltec cat is not up to the job! this was fitted by AMD when i had the exhaust done, any info?

    I don't understand why you'd need a new cat - is it related to the custom downpipe etc?

    Either way I'd trust what Ed is saying from my experience.

    Also from my experience do not get somthing this big done by someone you don't trust - I do trust APS by the way.

    you should have 2 cats!

    most ihi conversions use a 3 inch dp and a 100dpi (single) cat on a custom dp.
