The main concern about the Powerbox would be the actual main body of the exhaust. Anyone know whether its a convereted BGM or a SIP clubman thats used.
The interior baffles of the BGM pipes don't have a massive longevity in my experience (mostly V3's - but had the same issue on a V4)
I've started having them split / repaired / welded back up - but there is only so many times you can do that - plus its a pain when they come lose as its spoils the ride / trip. The V4's had additional baffles which reduced the performance too. If its the V4 BGM they are using - then be interested to know how this is being circumnavigated.
At £485 - i'd want some sort of reassurance that this is being stood up by supplier / manufactuerer for more than a season.
