Because Barker’s Exhaust was born on the Raptor platform, Barker’s knew the 2015+ single-port Raptor 700 deserved serious testing. What started as an experiment—building duals for a single-port head—quickly turned into a surprise. After hundreds of dyno pulls, multiple intake configurations, and extensive tuning, one thing became clear: the Raptor 700 truly loves a properly engineered dual exhaust system. The results weren’t just visible on the dyno—they were undeniable on the trail, track, and dunes.

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.
