The Scalvini KTM/HQ 125 exhaust is entirely hand-welded. The exhaust passes very close to the frame, so it can minimise damage as much as possible. Power improved during all the RPM range, especially at around 10500 Rpm (3.5 hp increase on 125).

Compatible with OEM silencer.

The improvement this exhaust makes is sensational. Right where you change gears, the stock pipe has a power/torque dip, which is completely eliminated by fitting the Scalvini pipe.

This is a "must have" item for race or serious riders.
