735588 1986 2006 Softailrace Version All Chrome 39

These Freedom Performance Blue-Proof Straights are the only complete 4.5-inch muffler system designed specifically for Softail models. They deliver significant gains in both horsepower and torque across the entire rev range. The setup features heavy-duty 16-gauge heat shields with a 2.5-inch outer diameter and 220-degree coverage to keep things looking clean. Inside, the race version uses a two-step baffle that steps up from 2.5 to 3 inches for a deep, throaty rumble. We provide all the necessary mounting hardware and brackets, along with O2 ports and plugs for earlier bikes. Just a heads-up for those on 2021 or later European Euro 5 models: you will need O2 sensor eliminators and a digital tuner to clear any check engine lights.
