This is the best and fastest exhaust with the exact same specifications as the exhaust that achieved a one-two finish in the 2014 Suzuka Mini-Moto 4-Hour Endurance Road Race Mini-Moto ST GROM Class, winning the class and finishing in 2nd place with overwhelming speed! This is the ultimate racing exhaust that has both the abundant torque that accelerates up to the Dunlop corner and the overwhelming acceleration when it enters the slipstream of the vehicle in front. Also, it was made to be fast and cool with the form of the popular Atomic Twin Exhaust in mind.This product is not only fast but also visually outstanding.
The development of the exhaust is done on the chassis dynamometer, and the base set is decided by the measurement, and then it is tested by the exclusive rider who is proud of WirusWin on the actual track. This is the ultimate racing exhaust. It's so fast you'll say, "How can a exhaust change this much?"
The racing exhaust is the same as the one used by the support rider in the race.There is no distinction between the pre-developed type used in the race and the commercial type, and the specifications that are judged to be the best in the current situation are immediately fed back to the product, so depending on the finish of the bike and the skill of the rider, it is possible to compete at the top.
It is all made of stainless steel with high durability and corrosion resistance. Easy bolt-on installation with no modification required. This kit is designed to meet all the requirements for the exhaust tip shape and size and can pass the competition inspection without any additional modification.
The sound volume is designed to meet the 99db / A limit set by the competition rules for the pursuit of performance, so it is quite loud.
*Special baffles (2pcs/set) are available for race events with strict volume regulations.The volume can be reduced by about 6db by installing it. *WirusWin has a kit for relocating the license plate and blinker lights (license plate lights are LED). This is the same product as the license plate and blinker relocation kit that comes with the Atomic Twin Exhaust.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
This is by far the best exhaust I have ever heard on a Honda Grom. Not only that it seems to really work up in the high RPMs. If you want to hold the throttle wide open this is the exhaust for you. Excellent craftsmanship. Can't praise This is by far the best exhaust I have ever heard on a Honda Grom. Not only that it seems to really work up in the high RPMs. If you want to hold the throttle wide open this is the exhaust for you. Excellent craftsmanship. Can't praise Wiruswin enough for this piece.View Detail
It turns neatly upward, but there is not a low-speed Torque because it is coming out too much. Characteristics do not match in Mini bike Circuit. It would be nice if you keep it fully open like Minimoto ...View Detail
