Customer Reviews
This is hands down the best exhaust you can buy for the Z650. This not only has the best exhaust note for a parallel twin, it absolutely brings the bike alive!! Almost completely removing the harsh engine breaking these bikes have. I have zero cons about this purchase but I have so many pros! You can feel the weight reduction under the bike, the exhaust note is absolutely perfect, the noise when cruising is almost non existent compared to what I was expecting from a full exhaust. Installation is very easy due to the high quality parts and workmanship behind “Yoshimura”. This system is worth every penny and I wouldn’t hesitate to buy it again if I had the opportunity.
