Dominator exhausts on Ebay - any experiences?

Hi, new to the forum, did a search but could not find anything on this question.

There is a polish guy on ebay selling 'Dominator' exhausts for a reasonable price, I cant really afford Akras or the like at the moment.

I just wondered whether anyone had any first hand experience of these exhausts and their performance / quality.

Also if anyone has any other suggestions about lower priced exhaust options they will be gratefully received.

Thanks in advance!
