【OVER RACING】Full titanium Megaphone Full Exhaust System 4-2-1 Exhaust System[special price] Review

5 points for sound +6, ease of installation -1

I searched for Japan Government Certificated, Short, and Megaphone Type and found no options, so I bought it.

Installation
In addition to Rear Stand + In-vehicle Jack, Glasses, plate latche, and other naturally necessary items are used as appropriate.
I am not good at removing Gasket.
Instruction manual is normal, only the exhaust pipe is hard to fit in the middle, and there is no description of the procedure of Cowl removal and installation, or Torque tightening.
Silencer Bracket is to be attached to the LINK of the rear suspension, but it would be better to have an on-board Jack for the car.
And Silencer, even with 4 layers of Washer, it hits the DrumstickDrumstick on the Swing Arm! (Image is that) 。
I ended up with a 10mm collar and a single Washer to float 0.5mm. (No image) 。
The supplied M8 bolt is not long enough, so a handheld cap bolt is used.

About Sound
Idling…The bass sound is at a level that makes me wonder if it is Japan Government Certificated. In the middle of a residential area, it is likely to be reported.
I use only 4000~6000 rpm for city driving… I use only 4000~6000 rpm for fuel efficiency, but the bass is nice when I start driving.
Winding…I'm satisfied with the Race ish sound of the Engine from around 6000 RPM, so I don't pay that much attention to the Exhaust SystemSound.

It is not too expensive for a full exhaust system, and it is worth buying rather than being stuck with an unfamiliar foreign-made product. In fact, the Idling sound was bigger than expected, but I have no regrets. View detail

Sound Satisfaction

The OEM Exhaust System has only been installed for about 2000km, so I don't feel that the ride quality has changed, but I recommend it to those who want to get as large a sound as possible with the JMCA Exhaust System. View detail

Suitable for intermediate level riders as the rear suspension load must be removed.

ASTRO PRODUCTS Front Wheel Clamp

ASTRO PRODUCTS 5tBottle Hydraulic Jack
The FrontClamp was used to eliminate accidental damage when hanging the Rear stand.
If you are absolutely sure that you will not fall down when hanging the rear stand, you do not have to do so.
Bottle jack was used to eliminate the load on the Rear Suspension. It is not necessary if you have an environment where you can hang it from the top instead of raising it from the bottom.
Bottle jacks were set up with Rear tire and Fender bracket.



We also prepared a 3/8 ratchet, but it was too narrow at the base of the exhaust system, so we had to use a 1/4 ratchet.
The sound, it's great.
Exhaust pipe, eh.
It smells a little Gas because the fuel mixture is not right. No choice. No way out.

I hope this is helpful View detail

First Full Exhaust System

This was my first time to install a full exhaust system on a motorcycle, and I was worried if I could replace it by myself, but I was able to do it successfully. The instruction manual was easy to understand with pictures, and the work was easy to do. The sound quality is excellent. The sound was a little too loud and might bother the neighbors, but I don't think you will regret buying it. The sound is too good from Idling, and I like the way it looks like H2R. And I like the fact that it is also lightweight. If you're not sure whether to buy it or not, just consult with your Wallet. w
The only demerit is that it is not a Gold amount that can be easily afforded, and when starting, you may have to turn it more than OEM.
But I'm satisfied with the price. View detail
