Fits: Harley-Davidson Touring models 2017-2026 (Milwaukee-Eight), 2009-2016 (Twin Cam) and 1993-2008 (Evo and early Twin Cam). Pick your bike and finish; part numbers are listed below. Headers only - run them with the 4.5 in. or 4.0 in. HP Plus slip-ons.

The Aggressor routes the exhaust under the frame instead of under the seat, which takes a lot of heat off the rider and passenger. 1.75 in. 16-gauge mandrel-bent, interconnected headers with a hidden crossover formed from 1.875 in. tube, so there is no loss of cross-section and better ground clearance. It flows more than the factory system, makes more top-end and still picks up low-end torque from the interconnect. 220-degree full-coverage heat shields, two 18 mm O2 sensor ports with plugs, gaskets and all mounting hardware included.
