Can't tell much from the picture but if it's mild steel it will probably be a Sportex and if it's stainless it could be a Miltek. The Piper on mine has no flexi.

Sportex I'd say as their originally black coated too (cant be 100% postive though) has a flexi as well which is in fact pretty decent after fitting to mine.
It's not black,it's stainless steel it goes that colour after time.
with a flexi, so what could it be? Milltek? Piper? Cant be protec or direnza as they dont have flexi's
