DRAGSTAR400 FI Exhaust System I did not think about exchanging, but there were many obstacles such as obstructing the lane change and banding. I understood that it is not harassment of Driver, I realized that I do not notice the existence of Motorcycle and exchanged the Exhaust System for safety. Exhaust system did not become noise, I made it to DAYTONA by saying Japanese Vehicle Inspection Correspondence. It took a day without tools and knowledge. The instruction manual consulted blogs etc.. The point of note was that it was difficult to change the position of Front and Rear of Gasket, Size of Rear, Joint pipe's Front and Rear, and SensorWiring at the time of installation. The exhaust sound is slightly larger than NORMAL and vibration and plosive sound are comfortable Level. NORMAL. Shea. Shea. Shea. Shea. DAYTONA. The. The. The. The. When opening it is boba baobo It is such a feeling.. Because of the sound, the low middle is Torque's feeling, the image does not grow high. I purchased Exhaust Guard separately from the included one. I thought it was to prevent scorching of Boots, but as I got on it, I changed the position because I'm worried about Pants when I get a better foot than Boots. Vichy is absolutely unreliable because it is hot. Town ride was very fun and I started delicate AxelControl to play comfortable Sound.
