Features:
Front Pipe Shortcut : While the factory front pipes are located on both sides of the transmission, the LAPTORR exhaust "consolidates the dual pipes to the right side of the transmission." This shortens the exhaust line, reducing exhaust resistance and forming the basis for an isometric layout.
The isometric layout centers around the cross pipe, and from the turbo to the cross pipe and from the cross pipe to the finisher, each has an isometric layout. The length of the 4-5-6 pipes from the turbo to the cross pipe is adjusted using a wave layout. This results in flat exhaust pulsation, improving exhaust efficiency, and producing a high-quality exhaust sound with high sound pressure.
Thoroughly Low Friction : By thoroughly achieving low friction without excessively large pipe diameters, the effect becomes even greater at higher engine speeds. The front pipes have been shortened, allowing for shorter pipe length. The rear silencer layout has been redesigned from the F-series model to reduce friction
Dual flexible tubes (when downpipes are installed) are used. The factory LAPTORR exhaust system uses a single flexible tube, just like the factory model, but by adding one to each of the dual pipes, an additional one is installed on the downpipes, improving vibration resistance.
Differential Heat Shielding: The exhaust pipes that pass under the differential/driveshaft are heat-shielded . The exhaust flaps operate according to DME control by using the factory actuators, so they are not recorded in the fault memory.
The exhaust sound volume is set to a comfortable level with the exhaust flaps open at high engine speeds and while riding at high speeds, allowing it to be enjoyed even while wearing a helmet. The exhaust pulse and frequency were controlled using an equal-length layout and rear silencer to achieve the highest possible sound quality and sound pressure. The exhaust flap volume is slightly louder than the factory flap when closed. The flap vibration noise when closed was reduced compared to previous models.
The product consists of
three parts: front pipe + two middle pipes + rear silencer
. Excluding the down pipe, the product is from the rear of the down pipe to the finisher.
