We had one with 197 cams and RS2 inlet, so circa 200bhp, worked well, sounded nice.
Did eventually fall apart but was a few years old at the time.
As is always the way with such things it of course chose to fail miles away when we were in the middle of a Ring/Spa trip, lol.
Luckily a quick favour from Rent4Ring with their welder sorted it:
So back on
and on with the holiday
Main reason for failure was just too much strain on the joints where its a bit poorly designed and not very well gusseted, if I had one again I would just weld a couple of extra brace bits on while its still new and im sure you would get 5+ years out of instead of the 3 or so ours did.
Really quiet exhaust, passed noise tests everywhere, was quiet on the motorway, and yet still sounded a bit sporty when you put your foot down.
I think its a reasonably good product, just needs a bit of extra bracing and you are sorted for ages.
