It did not mention that SP Tadao's HP or this purchase Page must separately purchase Gasket, it was written only in Small in the Instruction Manual that was included when it arrived.
Before purchasing various warnings, I'd like you to list it in an easy to understand somewhere where Large.
I thought that the sound became louder and the missing sounds improved. Just because I wanted to replace only Exhaust pipe, I did not personally care about the price side rather than buying OEM's Exhaust pipe again.

YOSHIMURA Slip-on Silencer R-11 CYCLONE, but I was a little uneasy about how compatibility is, but such anxiety blew away. In my case it was perfectly compatible and more than expected items.

I arrived yesterday and finished mounting earlier. It was about 2 hours after carefully reading the Instruction Manual. Since the Instruction Manual is solid, there is no problem with installation. Just remember to prepare for Gasket and Liquid Packing at the same time. By the way Gasket purchased for NINJA. One troublesome thing is that withdrawal of the COSensor's body side Coupler seems to be difficult unless Cowl is removed, it is a rough technique but only the side of the exhaust pipe is removed. Wiring is easy, but it seems that there is no possibility of disconnection if you remove 3 bound portions. Installation on PowerBox conversely turned Screw down after making Yore for Wiring. I am looking forward to trial running after the liquid packing has dried well.

Exhaust System is NORMAL, this Front pipe (Exhaust manifold) Only exchange.
I bought it by seeing SP Tadao's development blog. http : / / sptadao. com / chu / ?cat=166

There is a feeling that Torque up to about 3,000 to 10 thousand revolutions was added, and over 10 thousand revolutions does not feel change whether the Exhaust System is NORMAL.
The acceleration feeling at the moment of opening Axel and the lazy feeling of about 7 thousand are eliminated, pass - If you get on the street there is plenty of benefits and the overtaking of the car has become quite easy.
60km / h while cruising it has used the 5th speed so far, but not only became able to ride without Stress even in 6th gear, but if you get on Zwola 40km / I can get it even from around. The first gear speed can be used before replacement so the feeling of emblem will be improved and the emblem has become a mild feeling. Also in the defense range for 2nd start.

The volume increased feeling, the sound quality got thicker, and the sound like Bie We added.

As a replacement work, as a tool you need a tool that can remove 17 mm Nut with Air Flow Sensor cord. Afterwards it is convenient to have Praghan.
As necessary parts, Full Exhaust Gasket (KITACO KITACO : 963-1000012 can be used) I think that it is necessary. Exhaust System Joint Gasket(KITACO KITACO : 973-1000010) when exchanging pain when exchanging.
