Are you after one for your ZT-T 190 Carl? My Dad is looking at trying a Longlife system after buying a genuine Xpower back box and pipe. Nick and Jean at Austingarages suggested the Xpower may be a bit much for the motorway driving he does.
I had tried calling a few local companies, who also seemed to have difficulty obtaining prices easily, saying they were " quite rare " .
The prices for mild steel systems were only slightly less than Longlife quoted for a stainless replacement.
