I've been looking for the RS-4 US version and stumbled upon this beauty at WeBike. There's a number of difference between this and the US version. This for an instance is a lot quieter but it is missing the heat shield found on the US version. It looks a bit less cuz the US version is just awesome to look at with its side mounted exhaust hole and pre-installed bracket. Still, I like this better as far as sound goes and I don't think I have to repack this. Fits snug with the SP Tadao too!+Good looking exhaust+Pretty light, maybe 2/3 lighter than stock?+Good low-end noise-No heat shield-Requires a header for better low-end torque return

The sound is bigger than I thought

Performance, multi data FMF, built YOSHIMURA I got lost but determined by seeing both realities. It was impressive in the photo, but it is quite a good shape to wear (Shape like FMF or Sakura Industry) What is the impression of running in combination with TADAO, PB? Although the sound is said to be quiet, it is quite Large. ? The power of the beginning has obviously disappeared, but the middle-high rotation turns pleasantly. According to the future setting. Hope to Manufacturer Bracket to fix the car body and Silencer (A little bent Bracket) Orientation is obscure in Instruction Manual. This Instruction Manual looks opposite.

I made it because I go through JMCA

In fact I was attaching SP Tadayo's Exhaust pipe, so I thought about making it F4 F4 Q4, but I heard the fact that the delivery date has become considerably ahead of me and that I recently regulated the exhaust sound strictly, Then I made it to YOSIMURA RS 4 J that rumored that it is compatible with SP Tadao's Exhaust pipe though it is through JMCA.
At the beginning of the installation, exhaust leakage occurred between SP Tadayo's Exhaust pipe and struggled, but I managed to stop the exhaust leak somehow.
The sound is quiet and pleasant to flowing water.
It looks as if only looking at the Single Item, but it is pretty cool when installed.

No complaints

I was worried about which to do with FMF, but select YOSHIMURA with a relatively low attachment rate.
The manual was also polite, I did not have to adjust it again and it was easy to install. I use it in conjunction with PowerBox, but I do not need Gasket at the joint with the exhaust manifold ... I was preparing, but the liquid Gasket was enough enough.
Volume is noisier than necessary, I think that it is a range that does not have a problem personally. It feels good Yoshimura feeling at high speed.
Exhaust Spring's Rubber cover also has a stamp of YOSHIMURA because the art is fine (Lol)
