Having read about the dramas people were having after changing exhaust pipes and mufflers with O2 sensors and exhaust valve issues and alarms I looked at fitting the Arrows system from Aprilia. After i got up from the floor when I found how much they wanted for the pipe I searched out a business in Yatala, Queensland called Pipework Techniques. Noel came up with a carbon fibre Yoshimira can and cut off the original muffler after the exhaust valve and welded on the new can. I have to say the difference is mind blowing. The bike now pulls so hard from 1000rpm in 6th without a hint of hesitation. The sound is awesome. The overall performance has improved drastically and power is so smooth. My bike suffered badly from the O2 sensor at low revs previously. The work Noel did is bloody awesome. He retained the mounts for the original shroud over the exhaust valve and cut and reshaped the shroud to fit the new can. Brilliant job. If you live in QLD and want to upgrade your system go and see Noel. Hell of a tradesman.
