I ordered for a 2009 Yamaha C3 (USDM) and had zero issues with any part of my order or the product. The people at WirusWin are awesome, they were responsive and they asked questions to make sure they were building the right system. The exhaust system looks amazing, genuinely amazing. The quailty is 10x that of the options here in the USA and 1/4 the price. The sound is super weird, esspecially in the US where noise pollution laws aren't yet a thing. I do kind of love the sound though, it reminds me of 60's and 70's scooters, the sound profile just kind of fits. I did notice a slight performance loss compared to my 1" primary system I had built for it, compared to stock this would perform better.Overall, I have nothing negative to say about the ordering experience, WirusWin, or the product. This has been the best purchasing experiance I've had in a very long time and I'm extremely happy with the product.

A exhaust that is far removed from the image of conventional exhausts for scooters has been realized with the appearance of the 4-stroke 50cc scooter!
The tail end of the silencer is the first stainless steel silencer in the industry to be machined to the very limit under the engine case. It is very simple in appearance, but has an outstanding impact.
This product can be installed on Smart Dio and Zoomer as well as Clare Scoopy.
The volume and sound quality are quiet and light bass.The sound is not noisy or deafening, so you can use it on the street without worry.
This exhaust does not use glass wool inside the silencer as a common sound deadening material, and the internal structure is designed to suppress the sound, so the volume will not change unless the exhaust is damaged.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.

First of all, the sound of the muffler is so good. And the small and cute shape made Zoomer even cuter. The disadvantage is that the speed has decreased a little, but I don't care because the beauty of the exterior is greater.

I installed Bore up and High Camshaft and assembled.
When I ran the engine, the exhaust system was quieter than I expected.
Compared to the Normal muffler, the sound is more Large.
It's not a deafening sound, so I'm going to give it a full throttle when I'm done breaking it in.
Of course, I'm going to register it as a two-class moped.

I had a hole in my 50cc FICUB Normal muffler
Material on the cheap:I bought it because it's Stainless Steel and it's quiet
Easy to install, only took one person about 20 minutes
When I tried applying the Engine, the sound is certainly not annoying, it's more light and flaky than OEM
But when I test rode the bike, I found that the torque was too loose in the 50cc range
The OEM actually went from going up to 40km/h in 2nd gear on the OEM to not going
I can no longer go over 55km/h easily on the uphill
I wonder if you can install a Baffle etc. to counteract this? If you can't, you'll have to go back to OEM
Maybe it won't fit in 50cc
It's cheap and parenthesis good for those who are Bore up
