All I can add is that the sound
is fantastic
both at tick over and on higher revs.
One of the advantages
and disadvantages of the single side exit on my previous S2 was that it was quiet as a pussy cat on tickover and only barked when revved. The SS system is far more aggressive/boisterous all round.
Can't comment on the cost though Matt, as both times it was negotiated as part of the procurement process
