    I guess you mean fitting a K03S?

    Just buy one of these: http://cgi.ebay.co.uk/VW-Golf-GTi-B...CarParts_SM&hash=item58882cd9ac#ht_2406wt_911.

    OK, you have a decat already, but that's a bargin, and is bolt on and go. Perfect fit. Great bit of kit. Cheap too.

    how have you got a decat without a downpipe? the only way to do that would be to fit a dp/decat pipe,

    unless it's a bodge job where someone has pointlessly cut out the cat from the standard downpipe- the most pointless mod possible, as it's the downpipe that's restrictive, not the cat.....

    not really, it'll only smell of egg if it's over fuelling..... If it's running right it won't smell at all no matter how you drive it.

    the standard cat isn't restrictive at all really, not compared to the standard downpipe,

    So, if someone HAS cut the cat out on the standard downpipe then they're a clueless muppet who's done something based on ******** they've heard in the pub!

    Get a 3'' DP and Decat on there and let it breath out properly!
