QD increase their range with a new Twin Muffler Set for the HD Night Rod Special.

The system is comprised of a mid-pipe H balanced, and a twin conical muffler set in satin finish, with ergal machine worked end-caps painted matt black. The heat shield is stainless steel and also painted matt black.

The mufflers are equipped with a new technology device called GAS EXTRACTOR which increases the speed of the exhaust gases, gaining power and torque across the rev range, and also reducing noise to within the legal limits.

The power and torque values are 111.6 Bhp at 8840 rpm and 10.9 Kgm at 6440 rpm.

Also available from QD is the TuneUp Kit to maximise performance even further.
