Although it equipped with many things or being tried, the internal pressure control valve felt until now the thing of the natural specification made from NAG, race specification, or the lead valve type of the other company, and the difference which is ranks, so that it was not an overstatement, even if this Superb (SHUPABU) type was called final edition of the internal pressure bulb.
Although Kougami of the response was often heard as an internal pressure bulb being operative, the wonderful pleasant response which can carry out expression only to it bursts has been felt.
The spring may be built in and it may have yielded the effect.
It is already very pleasing, so that he does not want to attach an internal pressure control valve except a Superb type.
It is a super-recommend!!

What I was glad
? The body shock by Accelerator operation at low speed GEAR has decreased. ? Re-acceleration during 5th speed running became easier. ? Vibration of the car body decreased a little.
At the time of passing through the side waiting for traffic lights, we had made sure that the car body did not get cramped by Clutch work in the past, but only after Accelerator operation. Accelerator operation is more stable for light body, so go with ease and peace of mind. Also, when you are flying a lot on expressways and arterial roads, you can easily accelerate just by twisting Axel to overtake. Engine feel lightly and often turns better than before.
Sorry about putting on
? The feeling of beating of exhaust fade away.
Exhaust System is exchanging for dB's. Compared with Normal muffler, the exhaust sound is clear, so I felt good during acceleration, but regrettable that the feeling of the sound was slightly diminished.
I installed it myself but it's not easy. Even though it is SEROWExclusive Design, the Pipe diameter for Emulsion discharge does not match the AIPipe diameter. Is it because the emission effect drops otherwise? It was hard to install. It is better to have Tie Wrap ready for installation. After installation, the fuel economy feel a little better. However, since accelerating is pleasant, it is dangerous to worsen it if you carefully turn it around, so be careful. Since Body is installed in the vicinity of Air cleaner, it is in the Instruction Manual that the effect is Large, so installView Detail
