Kawasaki 300R shown in the video short exhaust pipe by Extremeblaster XB08 with closed cap and tunable plates. Header pipe was not cut down for this operation. Muffler was slipped over end and pushed down to its currant location leaving the end of the exhaust header halfway into muffler. Muffler pressurizes from the closed design giving normal performance for this style pipe with great performance and tone. Can be positioned anywhere along the length of the header pipe. Kaw 250R can have the same short pipe appearance however pipe must be cut to install muffler in short position otherwise is installed in stock mount. XB08 Extremeblaster does not need a fuel controller for full power operation and does not exhibit lean tendencies like snap crackle pop noises and can be further adjusted if desired by changing the number of plates at the rear cap for more power in the lower powerband with quieter tone or upper powerband with louder tone.
