There was a lot of chat about this a couple of months ago, i think the general opinion is single dump is better but i'm not sure how much, try a search for it over the last few months.

You wont really notice the difference. Both are far less restrictive than a closed neck which is standard on a scoob.
IMO Go for the cheapest and spend the spare dosh on something else
Just my opinion. Mine is a twin dump.

There's pros and cons to the various types of downpipe. There's an open bell-mouth (with and without splitter) and dual-dump pipes (where the dump tube joins close to, or far from - the main tube).
Open-neck pipes are claimed to allow earlier spool-up of the turbo and more low-range torque. Dual-dump pipes are said to give better top-end power at the expense of low-end grunt. Dual-dumps are said to be quieter as well, or at least can be quieter.
I went for a Scoobysport open-mouth downpipe, myself.

Lets see if this works?
