My Cat eliminater came from spareshack - see link
https://www.fastweb.co.uk/spaceshack...83c80ec 01675 It appears that the quality and looks of the quat-D had been improved a lot over the version I had - had a problem where it blew out the lamba plug hole and it had to be welded up and I was not the only one. Also I did not like the exposed clamps but they seem to have been taken care of . The ones in the link above look loads better than the ones I had.
I ran my bike initially with the udder and Termig end cans. I then de-catted it so my comparison is from Udder with termig end cans to Quat-D with termig end cans. Gut feel was more torque from mid range upwards. Gave more noise - such that at Cadwell track day I had to put baffles in termigs because it failed the noise test.
I have gone to a full termig system now - bit more power again but I think less noise possibly cos of longer header puiped and bigger diameter. Time will tell on the noise front when I go to Cadwell next year. I think full system is loads better but lots more money and very hard to get hold of. And the Quat-D does now look much better than it used to.
I will try to add a graph of the power change from termig ennd cans with udder to termig end cans and Quat-D
