COMMENTS FROM BARKER’S ENGINEER:
Barker’s single exhaust puts the power down low where you need it and really steps up the torque. Looking at the Dyno chart you can see that the torque gains start right away, at about 3,800 rpms with a 6 ft/lbs gain already and peaking with over 8 ft/lbs gain at 5,000 rpms. On the Big Bore Raptor having the gains in the 3-6k rpm range is vital to having a good all around performing machine.
