There are at least four downpipes readily available in the US that employ HJS catalytic converters:
1. Fabspeed 200-cpsi ($1395)
2. HJS 300-cpsi ($1495)
3. Akrapovic 300-cpsi ($1850)
4. Supersprint 100/200-cspi ($2432–$2822)
Given that I have the M-performance exhaust, which is already pretty loud with the valves open, I am leaning towards the HJS downpipe over the Fabspeed unit.

Where are you guys finding the 300 cell HJS downpipes in the US?
