【YAMAMOTO】SPEC-A Slip-on Silencer Review

It is a good item

I used it in exchange for Normal silencer.
It weighs about 1/3 as much and looks Race ish.
The sound is a little loud with an emphasis on the V-type EngineSound.
but it is not unpleasant.
Installation is easy. View detail

Titaniumium color is Race ish and it's cool!

Yamamoto racing's 2-piece Titaniumium Exhaust on a MotoBlogger or Hornet that I used to ride. (Full Exhaust System) I decided to buy it because the exhaust sound in the video was very comfortable and it looked exactly like I like it (I like Carbon, but I'm more of a Titanium guy).

The difficulty of installation was not so difficult, because I made it one out of the box.
However, it was a little Large strange to remove the Exhaust System from the OEM Exhaust pipe. The space is so small that it is hard to get the power ….
I've seen comments that the supplied gasket didn't fit properly, but I think that's probably because they didn't know the old gasket was stuck and tried to put it on and failed.
I was able to install it easily as usual by removing it cleanly with a slotted screwdriveretc.

I was very careful about Clearance with Rear cowl.
If you don't fix it in the perfect position, the angle of the Band becomes delicate, and the distance from the Cowl becomes too close, and it was difficult.

About the all-important sound.
I'm not sure if the Wool inside has been burned yet, but I've removed the Baffle and the sound is pretty subdued.
It has a very pleasant Sound with a modest but running high note.
It's a JMCA Certified Exhaust System, so it's not going to be a blast, and I don't want it to be a blast, but...
I'm looking forward to seeing the sound quality and volume change with a few more miles on it.

If the sound gets too loud, I'm going to run with a Baffle.

I can recommend it in general! View detail

Too good?

For CBR400RR.
Changed from Full Exhaust System called MORIWAKIMark2.
I had a hard time to get OEM exhaust pipe because Exhaust pipe and Exhaust System did not fit to each other (22000yen). The sound is not so loud.
The power band is easier to understand than before (on the contrary, the low speed Torque has decreased?). The ride has also become more enjoyable.
Recommendation. View detail

You'll know it when you drive it.

In 2003, it was installed on a re-imported car.
I bought it without hesitation because I had already had Yamamoto racing on another car before.

It's loud enough with the Baffle on, and quite loud with the Baffle off (I'm sure there are individual and individual differences.)
However, the good thing about this exhaust system is not the volume, but the good response to the opening and closing of the Axel and the ease of control.

And the sound quality.
Based on FeedBack from Race "Spec A Only the sound quality to boil Racer is very pleasant and makes you feel very comfortable.

If you're considering an exhaust system, not just the 600, we recommend that you consider Yamamoto racing. View detail

Clear sound, looks like the Racer at the time, good build quality

This is an in-play using a 90 year old CBR400RR (NC29) The SilencerMaterial is Kevlar, and Slip-on Silencer Type:Made to Order, with a delivery time of about 3 weeks

I drove the NC29 for about 20,000km on Full normal and I had no complaints about its performance at all On the other hand, when I was impressed with its high Potential, I changed to a good exhaust system My curiosity about the changes in the
In order to take advantage of the easy-to-handle characteristics of NC29 in the extreme Racer replica I went with Slip-on Silencer instead of Full Exhaust System Although there were several candidates, the exhaust system of motorcycle of 30 years ago was used for a Made-to-Order, but it's still a legitimate line up I decided to go with Racing The older motorcycles are really good at matching and diverting the original to the original Thank you very much In addition, the SilencerMaterials are Titanium, Carbon and Kevlar You can choose three different types, but I'll give you a respect for the then-illusive WorksRacerRCB400 I chose Kevlar to put it in

The Exhaust System that arrived was a little larger size than OEM The silencer of the old-fashioned cylinder is very cool now Kevlar Fiber also shines beautifully When I took it in my hand, I felt … that? It's not particularly large and light If you look closely, it may be to prevent sound cracking or to make it stronger Ring material is poured into the hole The End Baffle is attached, but I'll remove it immediately If I had to put such a thing on, I would ride in NORMAL
Let's install it to the body of the car Silencer band as written in the Instruction Manual And Clearance of Bracket is tight It may be the difference between the body of the car, but it is tight But the problem is solved by modifying the long hole of Bracket There is no problem in the connection to the exhaust pipe Gasket is not included So prepare yourself

When I turned on the engine, the thick exhaust sound made me grin. 99db (how about that for an NC29?) The sound is not as powerful as I expected There is Warming up in a residential area is better while driving
When you drive, you will find that you can get a little bit of pressure in the vicinity of Idling and in Situation where there is not much exhaust pressure The Torque feeling has been diminished, but it basically feels like it's torqued up in all areas It seems to be unnecessary to set up, but Carburetor's Jet/Needle is one of the best I touched the street and felt a definite improvement in performance When I did this, I recorded 65.1 horsepower Probably 2 to 4 horsepower was increased by this exhaust system I was relieved that the output characteristics did not change
The exhaust sound is extremely good; the middle class InlineFour is a buzzing machine The clear, penetrating exhaust sound is great No sound cracking, and the KevlarSilencer has a mellow sound similar to the Carbon I've been an OEM guy for a while now, but it's still good

Looks, performance, build and exhaust noise I am very happy with the looks, the performance, the build quality and the exhaust sound I recommend the Yamamoto Racing Exhaust System!
