Looks and Extra Power | Screamin’ Eagle Exhaust and Airbox - Baggers Magazine
01. On the bottom are mirror-chromed and flared FatShotz slip-on mufflers and muffler clamps. (Top) All of the components in the Ventilator air cleaner kit: protective rain sock with SE logo, gloss black low-profile air cleaner cover, high-flow filter element, backing plate, Screamin’ Eagle badge, and all required installation hardware and gasket.
02. Removing the saddlebag revealed the stock muffler. There are three fasteners securing the muffler; 2 on the muffler hanger (red arrows) and one on the muffler clamp (arrow) that were removed. Pardon the dirty pipe and wet bike—it was raining on the way to the install.
03. The stock muffler and clamp were slid off the header pipe and along with a new clamp the FatShotz muffler was slipped on and the 3 fasteners tightened to spec.
04. The same procedure was followed on the right side.
05. Any time a muffler/exhaust has been touched with bare hands it must be wiped clean before startup. Otherwise the oil in your hands, even just a fingerprint, will burn in and discolor the pipe.
06. A rear view of the newly installed FatShotz slip-ons; adding a nice tough to the rear of the Road Glid. The nonremovable black endcaps are held on with a security Allen Bolt (arrows).
07. The Stock football air cleaner cover was removed...
08. ...followed by the filter element and blacking plate (arrow)...
09. ...revealing the throttle body (TB).
10. The self-adhesive backing plate gasket was applied to the TB-side of the SE backing plate. Nice tough Harley; the glue on the gasket makes installation much easier.
11. The backing plate was fastened to the TB with two breather bolts (affows). Thne the three air cleaner mounting studs were threaded into the TB and torqued to spec. Thread locker was factory-applied to the standoffs.
12. The high-flow filter element was installed next.
13. Followed by the air cleaner cover and Screamin' Eagle badge.
14. The slip-on rain sock keeps the filter from getting drenched but still flows air.
15. To recalibrate the ECM a cable was used to link the bike to Harley's Digital Technician computer program. The proper map, based on the size of the motor and modifications, was downloaded in only a few minutes.
One of the fastest and easiest ways to personalize your bagger is with a set of slip-on mufflers that bolt right up to the stock head pipes. In addition, with the combination of a freer flowing air cleaner, there is extra power to be had.
We were looking to de-stock our 103ci ’11 Road Glide Ultra and liked the looks of the Screamin’ Eagle (SE) FatShotz 2-Into-2 Slip-On Mufflers (80847-10, $429.95). The FatShotz are tuned to maximize airflow while having a deep, but still legal exhaust note. They are EPA stamped and 50-state street-legal on stock displacement engines. Fitment is for 50-state, ‘10-later (plus ‘09 California) Touring and Trike models with dual exhaust. Installation requires separate purchase of two muffler clamps (65296-95A $7.25 each).
For the intake assembly we went with the SE Ventilator Performance Air Cleaner Kit in Gloss Black (29915-09, $239.95). A chrome version is available as well. The Ventilator features a low-profile exposed filter element that increases airflow into the engine to boost power. An included waterproof rain sock protects the filter in the rain. Street legal when used with stock mufflers. Fitment is for ‘09-later Touring and Trike models.
A dealer-performed ECM calibration was necessary to match the fuel and ignition maps to the increased airflow.
