New GUNSHIPS for Harley® Baggers Video
5" Diameter Universal Video
Tailgunner Exhaust utilizes the most sophisticated dynamometer equipment available to ensure you get the best performing pipes in the business. And when we’re done we ask independent master Dyno technician Rob Swartz of "Rob's Dyno Service" to check our results. Mr. Swartz’s expertise is instrumental in allowing us to ensure our customers receive the quality and performance they deserve. As an R&R certified Master Tuner, Rob’s Dyno has contributed to winning over a dozen Loudon Road Race series championships including Super-bike, Production Twin and the 600 series.

"The
results proved that the Tailgunner technology, in which the spinning
motion of the turbine tips creates a siphon which draws exhaust out and thereby increases flow, did indeed improve the Road King's power
output... A couple of horses and a few more pounds of torque are always
welcome, especially considering the amount of time these tips took to
install. So if your looking for a weekend project that not only
delivers a bit more power but also gives your ride a lot more eyeball,
Tailgunner GUNSHIP pipes are exactly the kind of project for you."

DYNO TESTED AND PERFORMANCE PROVEN
The above Dyno graph readings illustrate increased performance
results on a stock 2006 Harley Davidson Road King. The results represent the addition of Tailgunner Exhaust GUNSHIPS, B-52
JET-PIPES and DEDICATED TRUE DUAL HEADERS only. No additional tuning
or air / fuel mixture components were used.
Stock 2006 Harley Davidson Road King: (red graph line)
81.45 Max horse-power / 88.91 Max torque
Gains with B-52 JET-PIPES: (blue graph line)
4.21 horse-power gain / 5.84 Max torque gain
Gains with GUNSHIPS: (green graph line)
4.4 horse-power gain / 5.71 Max torque gain
Gains with DEDICATED TRUE DUAL HEADERS: (purple graph line)
1.28 horse-power gain / 2.47 Max torque gain
Increased Performance with
Proprietary Variable Back Pressure™
The Competition:
Conventional after-market exhaust systems typically allow for an overall decrease in exhaust
back pressure. This can result in increased top end performance and a louder sound, but often at the cost of decreased low and mid range performance (where you spend most of your time riding) and an earsplitting crack. Tailgunner Exhaust:
You get improved performance across low, mid and high end ranges because Tailgunner®
Rotary Cannons use turbine induced variable back-pressure. When
the turbines are spinning slowly they provide exhaust flow resistance and a small amount of
back-pressure. When the turbines spin fast they act as a siphon,
drawing the exhaust out and creating a very free flowing system. By
demanding a small amount of back-pressure at low and mid range rpm’s and minimal
back-pressure at high rpm's, you get an overall increase in performance
through the full power range. You also get a low, deep and throaty
sound. All the bark without the bite.
