I've got a 2001 bug-eye and already have fitted a Green panel filter, performance backbox and two straight through centre sections, removing the centre cat.

The car hasn't been remapped yet. If I fit a sports cat downpipe will I be able to get away without a remap?

Well you can get away with it, yes. But it's worth doing and the downpipe will have made a difference, effectively upping the flow rate of the whole exhaust from the turbo back.

I have always wondered myself as well. Wouldnt mind a full decat but cant afford the re-map just yet!

I am planning on having it remapped at some point in the not too distant future, and fitting a sports cat downpipe is part of the plan to get the most from any remap.

I know you are strongly advised to remap a newage if fitting a de-cat downpipe to prevent overboost and other problems. A sports-cat downpipe should offer 'some' back pressure at least, but I don't want to push it too far to be anything other than safe on the standard map.

Glad it looks like you can get away with it. They are going for a good price on the H&S group buy running at the moment.

^ suggest get yourself a boost gauge (if you haven't already) so you can see if it is boosting higher than it 'should' without a re-map..
