WILL A TAILGUNNER™ FIT MY BIKE?
Tailgunner® GUNSHIP models are an easy, direct-fit, installation for all Harley-Davidson touring bikes (baggers.} Everything is included for you to perform a quick, effortless installation and easy to follow directions are included. We also offer custom, universal fit models for everything else. Just determine if there is 4″ diameter of clearance where the mufflers will mount on the bike and what the outside diameter size the exhaust pipe is where the muffler slips on. All universal models include a support bracket on the backside of each model. Tailgunner® universal fit models are a simple installation on many bikes. With others a certain amount of modification, such as a support bracket and inlet adapter. This is an expected and enjoyable part of custom motorcycle building. Tailgunners® are mounted on everything from stock Harley-Davidsons to metric cruisers and sport bikes and will slip-fit onto most after-market exhaust systems as well.
ARE THE BAFFLES REMOVABLE?
Tailgunner offers a baffle installation and removal service so you can be assured you get just the sound you want. Some disassembly of your muffler is required to remove or install a baffle. To retain the one-year mechanical warranty we invite you to allow us to provide this service for you. The service cost is $39.00 plus shipping. Turnaround time is typically only 1-2 days. Please call to schedule your service.
WHAT IS THE INLET SIZE OF THE UNIVERSAL MODELS?
The universal Tailgunners® will slip fit onto any exhaust pipe from 1.5″ through 2.5″ using our CNC machined adapters. The stock inlet size on 4′ and 5″ universal models is 2.5″ However, we offer CNC spun aluminum adapters to allow mating with a variety of exhaust pipe sizes, manufacturers and configurations. American and metric. The direct application models are designed to mate with their respective motorcycle models.
HOW FAST DO THE BARRELS SPIN?
Barrel speed is determined by how much and how fast the exhaust gasses are passing through the turbine system. This “flow” is established by engine displacement and exhaust configuration. A 2 into 1 system moves more air than a 2 into 2 system. The barrels spin quite easily and are designed not to “over-speed.” The barrel assembly is powered by an internal stainless steel, dual turbine system. The turbine is also responsible for drawing exhaust out of the pipe at high RPM’s. This system is what gives Tailgunner® Exhaust the advantage in producing an exhaust pipe that performs well and sounds great at all range and speeds.
WILL THE BEARINGS LAST IN THE HOT, CARBON ENVIRONMENT?
Tailgunner® exhaust uses the highest quality American shielded radial bearings in each model. They are designed to resist heat and corrosion and have a 100% success rating to date. To ensure smooth, even rotation of your rotary cannon exhaust barrel assemblies it is occasionally necessary to remove carbon build up within and around the bearings. The recommended interval between cleaning is approximately every 1,000 miles. We recommend using an aerosol spray solvent such as WD-40 for cleaning. Please Note : The bearings are not under load. They are freewheeling and well below their maximum temperature, load and heat limits.
DO YOU HAVE MAPPING FOR MY BIKE?
TAILGUNNER offers the best, most advanced and easily installed fuel injection tuner on the market. The RIDE-MAXX plug and play “5 minute wireless install” provides more power, more mileage and a better ride. The best part of all this is that the RIDE-MAXX comes pre-programmed with the correct map for your motorcycle. There is no need to download and install maps. This gives you optimal performance and also saves you time, money and frustration. The RIDE-MAXX is available for Harley Davidson Delphi equipped fuel injected 2002–2009 touring and 2001–2009 Softail models. Learn more at: www.americanmicrofuel.com For UNIVERSAL FIT models: Motorcycle tuning is a complex skill that is contingent on many factors. A tuning map may work well on an application that is otherwise OEM and stock. However, we find that many of Tailgunner® customers have already made modifications to their bikes. A good, qualified Dyno technician will be able to tune your bike.
CAN I TUNE A FUEL INJECTED (EFI) BIKE WITHOUT MAPPING?
Yes. There are several options. We recommend a Dynojet Power Commander. They are affordable and user friendly. Please visit their site at: http://www.powercommander.com for a lot of good information. Power Commanders are the perfect answer for owners that are making basic air cleaner or exhaust pipe changes on fuel injected models. The above product is manufactured with consumer installation in mind. i.e. plug and play. Any competent, qualified motorcycle service center can also perform these services. We suggest talking with them first to ensure they are familiar with these products.
CAN YOU RUN BOTH PIPES OF A BIKE THROUGH ONE TAIL GUNNER EXHAUST?
Yes. A two into one is an easy installation and provides the best performance gains.
HOW MUCH RESTRICTION DO I GET WITH A TAILGUNNER®?
Tailgunners® were designed to allow your exhaust to flow as efficiently as possible. They are an extremely free flowing slip on.
WHAT KIND OF PERFORMANCE INCREASE CAN I EXPECT?
When properly tuned you will enjoy a moderate increase in both horsepower and torque. Generally in the neighborhood of 4 to 5 lbs of torque and horsepower. Please see the “Performance” page.
HOW MUCH BACK-PRESSURE?
Tailgunner® slip-ons are designed to be as non-restrictive (free flowing) as possible while giving you a deep, throaty sound. The most noticeable changes with a Tailgunner® are the improved sound, aggressive styling, weight reduction and a extra horse power and torque.
WHAT DO THEY SOUND LIKE?
The GUNSHIP™ models are louder and deeper than exhaust. A deep, low, throaty, big bike sound is the best description. These models come stock with a 10″ fiberglass packed baffle and have a 2.5″ core. They are also available un-baffled. The universal models are loud, deep and throaty. The bark without the bite. Please listen to the universal audio file or video on the website.
WHAT ARE THEY MADE OF?
Our housings are made of either 16-gauge steel or stainless steel depending on the model. All units are chromed to perfection or highly polished if stainless steel. The barrel assembly and turbines are a combination of stainless steel and brushed aluminum. All hardware is stainless steel. Every Tailgunner® is made in America.
WHERE ARE TAILGUNNERS® MADE?
Tailgunner® Exhaust manufactures and assembles all of its products in the United States. We believe this is the best way to ensure our products quality.
HOW DO I MEASURE THE OUTSIDE DIAMETER OF MY EXHAUST / HEADER PIPE?
Universal 4″ and 5″ Tailgunners are a slip fit installation. This means the pipe slips on OVER your existing exhaust / head pipe. For an accurate measurement remove the current muffler and any heat shields so the end of the exhaust pipe is exposed. Simply measure the pipe opening from outside top to outside bottom or left to right. Remember, you are measuring the outside diameter as Tailgunner models slip over the existing exhaust pipe. Please see the “universal adapter instructions” under the Tailgunner® Info drop down menu.
DOES TAILGUNNER® OFFER A WARRANTY?
Yes. All Tailgunner® exhaust units come with a full one year MECHANICAL warranty. This warranty covers and is limited to the repair or replacement of any unit due to manufacturing defects at the manufacturers discretion. We do not warranty chrome products against discoloration. Even the best chrome in the industry may discolor if made hot enough. Please ensure your bike is tuned correctly.
I LOVE MY UNIVERSAL FIT TAILGUNNERS® BUT SOMETIMES THEY ARE A BIT LOUD FOR MY NEIGHBORHOOD. DO YOU OFFER ANYTHING TO QUIET THEM DOWN A BIT?
The Tailgunner® R&D team is developing our own internal baffle system so you will have the option of reducing sound levels while maintaining a very free flowing unit. Until then, we suggest using a generic insertable baffle in the exhaust pipe right before the Tailgunner®. They come in a wide variety of sizes, are inexpensive and available through many sources. The universal Tailgunner® rotary cannon exhausts are more accurately described as a resonator rather than a muffler.
HOW MUCH DO THEY COST?
Please see the “Shop” tab on the website. All models are priced. Stealth black models have an additional cost and ship time.
HOW CAN I ORDER?
Directly from Tailgunner® by telephone, (508) 693-1944. On our website (Shop Online.) Or through one of our authorized dealers. Please see dealer page for locations.
