I'd like to warn all Yamaha RXZ owners to be very careful when replacing your leaky and noisy exhaust pipe. I had this bad experience with one bike repair shop in Midview Building, Bukit Batok where I brought my RXZ for piston replacement. The mechanic advised me to change its exhaust also because it had a small puncture. He then fitted a new exhaust which he claimed was original part as it was engraved with the words "Yamaha 3BS" on the chromed end of the exhaust. I was charged $90 for the exhaust alone.
I really regretted letting him do this as I realised later it was in fact a fake part. It made so much noise that I had to go back to the shop for rectification 3 days later. Despite all efforts, even a more experienced mechanic of the shop was not able to solve the problem.
The main issue with this fake part is that it uses a much thinner pipe or cylinder. Becuase of this, it works like a sounding box. Another problem is, internally, it does not have the same structure as the orginal part that is meant to hold the muffler firmly inside. As a result, at higher rpm, the muffler starts to vibrate and makes the exhaust even noisier. Although the experienced mechanic stuffed a lot of fibre around the muffler to damp the vibration, the exhaust still made a lot of noise.
Worse, due to the excessive use of fibre which I believe has interfered with the proper functioning of the exhause, the bike loses its power.
So if you do not want the same thing to happen to you, be very careful the next time you change your exhaust. I would advise before you allow the mechanic to fit the exhaust, knock the chromed end of the exhaust a few times. If it sounds thin and ringy, reject it. You shouls also check whether it is stuffed with fibre. If it is, better not take it as a good exhaust does not need fibre at all.
Hope this can benefit all the RXZ owners.
