Vance & Hines Fuelpak

A brand-new bike is truly a thing of beauty: perfect gleaming paint, flawless chrome, and the taut feel only a zero-mile machine can impart. The euphoric sensation of moto-newness is heady stuff that, deplorably enough, tends to not last anywhere near as long as the payments do. After a sadly short time, the luster starts to fade, and the inherent flaws of the bike likely begin to surface. The classic, flowing lines soon begin to look just like hundreds of other classic, flowing lines; or perhaps the seemingly endless acceleration finally faded out; or, very possibly, the throaty burble only a V-Twin can produce begins to sound a bit like a lawnm ower.

Such is the plight of the humble stock motorcycle and the call to action of the aftermarket. Luckily for us, this call went out to the folks at Vance & Hines (V&H), and they offered to help unleash the power and beauty of our '06 Street Glide. Twenty-five years of manufacturing high-performance exhaust systems has brought the company to the very top of the market, and it continues to back up that success with a host of horsepower-boosting innovations. However, our fuel-injected bike also required a bit of electronic fine-tuning in addition to an exhaust system to produce the results we desired. Well aware of the effect their handywork has on the simplistic brain of your basic EFI system, the engineers at V&H developed a tuning tool they call the Fuelpak to help realign fuel delivery with increased intake and exhaust flow. As an added bonus, the install is user-friendly and can be done with basic tools and a dash of mechanical aptitude. We selected the V&H Dresser Duals head pipes, along with the company's oval slip-on mufflers. The team at V&H also recommended installing an H-D Screamin' Eagle high-flow air-filter kit along with the Fuelpak for optimum results.

1. We started with the air-filter swap and pulled off the stock cover.
2. Although the cover is reused, almost everything behind it was pulled off and tossed, including the big plastic backing plate.

6. The stock cover goes right back on, and no one is the wiser that you have just added several horsepower. However, the ECU knows, so we'll have to address that later.

7. Both saddlebags had to come off to get to the exhaust. We also removed the right-side floorboard as well as the passenger board in order to remove the OEM exhaust. Again, access is easy, and the parts came right off.'

9. Mufflers mount via pinch clamps to the header, and the two bolt to a floating bracket under the saddlebags. The pinch clamps can sometimes require a bit of finesse and penetrating lubricant before they'll let go.
