 'I would just like to say that I would recommend a Zorst Exhaust to anyone who wants (a) top quality workmanship; (b) excellent customer service; (c) an awesome looking and sounding after market system; and (d) 110% value for money.'

BMW K100

  The K100 factory silencer unbolts and the new one slips onto the 4 factory headers. It's a straight swap. (as are most of our systems)

  customer comment

'Hi Graeme,

The exhaust is fantastic.

Great sound. Butterfly damper in the 10% position.

Have not tried it anywhere else. Will see how it performs on a trip in the next few weeks.

Thanks again. Regards

Andrew Kidd.'
