Better than I expected.

It took a little over a month from order to arrival. The box was nice, but I was disappointed in the way it was packaged, which was on the average person's Level, with advertising paper and newspaper all over the place (lol).
The chamber itself was well made, but the silencer surface was rough as if the aluminum material had been filed, and I immediately buffed it with a compound. I was a little disappointed that the sticker is not included, and the installation instruction manual is just a sheet of paper, so it is not very clear on how to install it. It seems to be difficult for those who are new to replacement and those who do not have proper tools,
I was concerned about the low speed power since it is a dual silencer, but the ride quality was the same as a certain BurkSP, but the maximum speed is about 90km/h with the custom big cab only. View detail

Looks great, performs NORMAL, sounds so-so

The performance is almost the same as NORMAL etc.
It is easy to ride because it has Torque in the low and mid RPM range.
The high rpm is also about 11,500 rpm, the same as NORMAL.
Neither good nor bad

The sound is like a slightly larger version of NORMAL.
At best, it's fairly quiet. At worst, it sounds lame.

The Silencer is more prone to clogging than I expected, and replacing the Wool is a bit of a problem if it's your first time.
If you don't skip the back side of the Rivet, you can skip the front side.

Heat resistance [Color] Clear flies quickly, so I went with the heat resistant Titaniumium color.
At least it looks good! It's so cool!
If you combine it with the DummySilencer and make it look like a 4-piece, it looks like an NSR500!
I'd rather have a ROTHMANSCowl than a Silver TerraCowl View detail

Dual Exhaust System is Cool

Actually I was expecting muffling performance, although it was loudly ordinary though, it was warranted as if it is good from Cool!
Would it be nice if we could reach Up a bit more if possible View detail

First, it is expensive. Although it is , there is worth of that. The exhaust port is also small good touch!! sound is mild touch. interference -- nothing -- vv
