It looks great! The exhaust noise is subdued, but at high revs it's enough to make you chuckle through the Helmet! This was my first time installing it and it went in with no problem!
I wondered for a minute which one was what number, but it was numbered on the exhaust pipe! (*•??•?*) ? ??

Performance, products are rare for this kind of product on HP
The dyno as published? But it has been proven and is naturally good
The troughs of the VTEC are also eliminated so you can use the rpm range in that area as well

As for the 400ccClass Exhaust System, sound quality is good, NORMAL seems to be insufficient to compensate for the drop of Torque in a certain rotation range, Power that does not require high rotation is a trick.

We set it to Oval of Wyvern only setting.
I saw the manual, but I feel more polite than other Manufacturer.
Although there was no description, I have Spring hook. I got hurried and bought it....
Spring's resonance prevention stretch Tube was also attached.
The goods themselves are to say, Large strange is a wonderful build.
I got a sticker with a bonus, but if it is white of the car body Silver is not conspicuous, sorry.

Both the burnt color and the accuracy is perfect.
It has 1mm space between the bottom of the engine and it's awesome.
When mounting you must remove the anti vibration gasket located near the mounting screw of the exhaust pipe orelse it'll touch the pipe.
It sounds really cool but I installed an inner silencer because I felt it was too noisy for my neighborhood when warming up the engine.
Instructions say that the sound corresponds the Japanese automobile (safety) inspection at the limit.
The structure and all is fantastic.
