01. Here are all the V&H; components that are going to be installed on the ’10 Street Glide. A) The Power Duals head pipes, which comes with all the mounting hardware and heat shields, B) Monster Rounds mufflers, C) ThrottlePak, D) FuelPak, and (E) VO2 air filter kit with Duke cover.
02. Here’s the SG up on the lift. As you can see, the tech, Matt Gazzetta, has already removed the saddlebags and stock intake setup. Also notice the stock 2-into-1 pipe. Kyle didn’t like the look of this pipe so that’s one of the reasons why he went with the Power Duals header system.
03. Before mounting up the VO2 kit, Matt worked on installing the ThrottlePak. Installation was extremely easy, first he made sure the main handlebar switch was in the off position, then he unplugged the Throttle Control Actuator (arrow)from the left side of the throttle body and plugged the female ThrottlePak connector in its place.
04. The ThrottlePak male connector (red arrow) was plugged into the factory female connector (yellow arrow) that was removed in the previous step. And that was it, the ThrottlePak was installed. Matt then routed the assembly and wires around the bottom of the throttle body and to the top side.
05 Here you can see the ThrottlePak wires routed around the throttle body (arrow). Matt then installed the VO2 support bracket with the supplied breather bolts and secured the ThrottlePak to the support with zip ties. The ThrottlePak will work with any exhaust system or fuel tuner and will work just as good on a stock or modified bike. Basically you could install just a ThrottlePak on a bone-stock bike and feel a noticeable improvement.
06 Next the filter backing plate and aluminum venturi were installed. The rounded edge design of the venturi helps accelerate airflow and direct it into the throttle body.
07. Matt then installed the breather hoses. The hoses fit over the breather bolts, slip through the filter backing plate, then loop around the venturi back towards the throttle body. The filter mount bracket (red arrow) was then secured in place.
08. The filter was then bolted to the mounting bracket with the supplied bolts.
09. The Duke cover was then installed. Available in chrome or black finish, the black matches up perfectly with the Black Denim paint on the SG. For a clean look, the cover is secured with three bolts that bolt into the backside of the filter backing plate.
10. After installing the stock exhaust flanges and retaining rings, Matt applied some anti-seize to the stock O2 sensors and threaded them into the bungs on the Power Duals head pipes.
11. With thread locker on the bolts, the header side-mount bracket was loosely secured to the bottom of the trans.
12. The right-side floorboard was then unbolted and the head pipe was loosely mounted to the heads. Spacers are provided to space out the floorboard so the front head pipe will fit between the floorboard and engine. V&H; supplies its own performance exhaust gaskets with head pipes.
13. Most exhaust gaskets are conical and are prone to interfering with the exhaust port if over-tightened and crushed too far. The V&H; performance gaskets are much smaller than traditional gaskets and will not impede exhaust port flow, but a little extra care must be taken to ensure that pipe alignment is correct and that the flange nuts are tightened evenly for a good seal. On the left is the V&H; performance gasket, on the right is a standard conical gasket, and up top is a conical gasket that was just slightly over-tightened and therefore misshapen.
14. Here’s a close up of the Power Chamber. As mentioned earlier the design was created to give riders the benefit of a 2-into-1 but with the looks of a 2-into-2 system. The proprietary crossover is designed to maximize the volume of both mufflers to improve scavenging of each cylinder for a more efficient combustion.
15. Like on the ’09 and ’11 touring models, to help reduce heat on the passenger’s legs, the rear head pipe on the Power Duals was routed under the frame and behind the trans pan. Matt connected the cross pipe to the head pipe and loosely secured the two with the supplied Torca Band Clamp. As you can see, the crossover pipe will be secured to the back of the trans pan with the supplied bracket (arrow).
16. After plugging the O2 sensor wire leads back in, Matt slid the mufflers into position.
17. A close-up shot of one of the end caps reveals a CNC-grooved machine finish that not only helps the caps sparkle in the sun but also give them a jewel-like appearance.
18. With the Power Duals and Monster Rounds in place, Matt installed the heat shields and tightened everything down.
19. When it comes to the FuelPak, V&H; provides a bundle of papers loaded with settings for various bike models and parts combinations. Like we mentioned before, the FuelPak can be used with all V&H; components or it can be used with a mix of aftermarket header/muffler combinations.
20. If you are near a computer you can also go to the fuelpakfi.com website and simply enter all the information for your setup, and it will give you all the settings for your specific application. This is a much easier way to go than sorting through all the listings and looking back and forth as you input the numbers.
21. Just like the ThrottlePak, the FuelPak is really easy to install. Matt simply unplugged the factory wiring from the ECU, then plugged the FuelPak into the ECU (red arrow). The factory wiring was then plugged into the backside of the FuelPak (blue arrow). The ECU assembly will then fit back in its plastic tray but first the left ECU hold down has to be cut off.
22. Matt then turned on the main power and handlebar switches (but didn’t start the bike) so the FuelPak would light up. He then programmed the FuelPak using the settings he downloaded. The left button (red arrow) is the mode select button and the two right side buttons (yellow arrows) are the value-adjustment buttons. The top is to increase the value; the bottom is to decrease the value. Most of the cells in the FuelPak settings contain a number that determines how much fuel is going to be added or subtracted according to the rpm and throttle position. Other types of data found in some of the other cells include software version and rpm value to set an evaluation point. Once all the settings were programmed in, Matt followed the instructions for turning the power on and off and verifying all the modes, and the install was complete.
23. After a quick testride, the bike was put back on the dyno for some results. The bone-stock bike put out 68.97 hp and 81.40 lb-ft of torque. After the install the bike gained 16 percent more horsepower (80.12) and 10 1/2 percent more toque (90.08). Looking at the graph, you’ll notice the torque has a nice broad curve in the 3,000-4,000–rpm range making the bike really fun to ride in that range. We got some seat time and definitely noticed the pick-up in power and the new found torquey-ness of the bike really made it fun to ride.
With more than 30 years in the exhaust industry and backed by just as many years of racing, testing, and product development under its belt, Vance & Hines (V&H;) has become one of the most popular companies to go to when it comes time to add some juice to your ride. And for good reason, the company has a stacked lineup of components when it comes to improving the sound, power, or performance of your ride, no matter if it’s an Evo Softail or Throttle-by-Wire bagger. From mufflers to intake kits, fuel tuners to header systems, V&H; has just about something for everyone. With so many products in its lineup, V&H; is basically a one-stop hop-up shop. You can satisfy your performance needs all through V&H; or just piece something together combining V&H; parts with other manufacturers’ components.
For this article, our concern is a bone stock ’10 Street Glide. Like many new bike owners, Kyle was looking for some quick and easy bolt-on power and a deeper note from his exhaust. Cruising through the V&H website, Kyle found a plethora of exhaust/muffler options, a couple of hi-flow air filter kits, the FuelPak EFI tuner, and a brand-new product geared directly towards Throttle-by-Wire bike owners, the new V&H ThrottlePak—essentially everything he needed for his intended upgrade.
While his stock ’10 Street Glide came with the 2-into-1 exhaust setup, Kyle wanted the more traditional duals look. Sorting through the V&H; website he found the Power Duals ($519.95, PN 16769), which provide the balanced look of one muffler sitting beneath each saddlebag, but also provide the added performance of a 2-into-1 with V&H;’s exclusive Power Chamber design on the right side of the bike. Basically the two head pipes meet down by the transmission and form an X-shaped crossover system, which helps scavenging of both cylinders. As for mufflers to back up the Power Duals, Kyle opted for V&H;’s new 4-inch Monster Rounds ($649.95, PN 16773). Similar to the company’s popular Monster Ovals, Kyle was drawn to the Rounds because they claim to offer a mellow and deep rumble that isn’t too loud or obnoxious to listen to on those 300-plus–mile rides. The Rounds feature V&H; Blue Proof technology and CNC-machined endcaps. To feed more air into the engine, Kyle chose to go with a black Duke air cleaner cover for the VO2 Air Filter kit ($279.95, PN 40007). The VO2 kit is designed to flow more air with its large washable/reusable filter element, larger inlet backing plate, and a billet venturi. The kit is available with several cover options in either chrome or black, or can be used in conjunction with most stock covers.
With the head pipes, mufflers, and air cleaner taken care of, next came the electronics. To help get the fuel delivery on par with the hi-flow intake and freer flowing exhaust, Kyle picked up the V&H; FuelPak ($279.95, PN 61009). Already lean from the factory, the addition of the pipes and air cleaner would make the bike run even leaner and hotter. V&H; designed the FuelPak as a simple plug-and-play solution to get your bike running cooler and the air/fuel ratio in the right parameters. The FuelPak adds and takes away fuel as needed to create a very precise air/fuel delivery. Aside from being easy to install, the FuelPak is easy to program with a large assortment of component combination options that go well beyond just V&H; products, allowing you to use only the FuelPak and just about any another manufacturer’s headers, mufflers, and intake kits.
Lastly, Kyle wrapped up his component selection with the new ThrottlePak ($219.95, PN 66001). Designed specifically for Throttle-by-Wire owners, the ThrottlePak was created to improve throttle response and eliminate the lag many have experienced with this newer throttle system Harley has implemented. According to V&H; the ThrottlePak modifies the speed and degree to which the throttle body opens the throttle plate, and it only affects the opening speed and not the fuel curve, timing curve, or any other sensors. The ThrottlePak responds to your throttle grip movement, moment-by-moment adding the right amount of assist to deliver the responsiveness you’re asking for whether it be quick to get around a semi, or slow and steady like when on wet or unsteady/dirty surfaces. The ThrottlePak does not take over control of the throttle, that still lies with the stock ECU and everything happens within the ECU’s standard safety protocols.
While V&H; provides detailed installation and operating instructions packaged with all its components, as well as a PDF version available for download via the part number links on its website, Kyle wanted to get some before-and-after dyno runs, so we tagged along with his bike as it was dropped off at Anaheim-Fullerton Harley-Davidson for the dyno runs and install.
