HPRD KTM/Husky/GasGas 250/350 High Velocity Exhaust Flange
KTM, Husky, GasGas High Velocity Exhaust Flange 250 and 350 models.
The stock exhaust flange on your 250/350 is oversized at 38mm. CNC precision-crafted in the USA by the same team behind HPR’s race-winning engines, this flange tightens the transition zone, reduces dead volume by 30%, and sharpens the pressure wave intensities and exhaust gas velocity remains more constant with less turblence exiting the port for dramatically improved throttle delivery.
What does that mean for you?
-
The bike feels more alive and exciting off the bottom.
-
The throttle feels directly connected to the rear tire.
-
The engine revs quicker and responds faster in every gear.
-
Every crack of the throttle delivers an instant burst of torque rather than the typical KTM dead feel.
We spent nearly 2 years perfecting our flange, which started when we saw some of the tricks Triumph was doing on their release of the TF250.
Be maintaining the exhaust port cross sectional area more consistently we improve flow, exhaust pressure wave, pressure recovery is improved for more efficient flow.
Works on OEM, FMF and most aftermarket Exhaust systems.
