Screamin’ Ea­gle High-Flow Ex­haust Sys­tem

We de­cided to do a Stage I kit on our bor­rowed 2017 Road King. We pre­vi­ously in­stalled the Screamin’ Ea­gle Heavy Breather Air Cleaner Kit (part #29400263; $399.95), and now it was time to up­grade the ex­haust. We or­dered up a High-Flow Ex­haust Sys­tem with Street Can­non Muf­flers from Screamin’ Ea­gle (part #64800059; $1299.95) as well as a Pro Street Tuner (part #41000008C; $299.95) to re-flash the ECU. We or­dered the TwoPiece 4.5-inch End Caps (part #65100078; $149.95) to fin­ish off the muf­flers.

We de­cided to go with chrome just to stick with the rest of the bike, but you can get the ex­haust sys­tem as well as the air cleaner in black.

The Mil­wau­kee-Eight is the new mo­tor in the 2017 Har­leyDavid­son Tour­ing mod­els, and it has a very dif­fer­ent sound from the Twin Cam en­gine. It isn’t as deep as its pre­de­ces­sor, but it has a great ex­haust note—just not as deep as the Twin Cam. In­stalling a full sys­tem from head pipes to muf­flers not only helps the per­for­mance, but it also brings that deep rum­ble back to the bag­ger.

The com­bi­na­tion of tuned­flow head­ers and Street Can­non muf­flers with re­lo­cated cat­a­lyst max­i­mizes horse­power, main­tains solid midrange torque, and man­ages heat. The High-Flow Ex­haust sys­tem is 50-state US EPA com­pli­ant. The large in­let 4.5-inch Street Can­non muf­flers fea­ture baf­fles that are op­ti­mized for ag­gres­sive per­for­mance and sound un­der ac­cel­er­a­tion and de­liver a rich, mel­low note.

Fol­low along as we in­stall the Screamin’ Ea­gle High-Flow Ex­haust Sys­tem on our 2017 Har­ley-David­son Road King.

With the sen­sors and flanges at­tached we in­stalled the head pipes to the heads fin­ger tight—do not tighten all the way at this time. 2

We then in­stalled the front head pipe re­tain­ing band clamp and also tight­ened fin­ger tight. 3

We then moved our at­ten­tion to the cross­over pipe. We slid in the gas­ket to en­sure a tight leak free seal. 4

First things first, we in­stalled the head-pipe flanges as well as the oxy­gen sen­sors. 1
