737263 Softail Deluxe Heritage Sport Glide Slim Street Bob Fat Bob

The Freedom Performance Blue-Proof Straights are the only complete 4.5-inch muffler performance system available for Harley-Davidson Softail models. This system is designed for massive horsepower and torque gains across the entire rev range. It features 2.5-inch outer diameter, full-length heat shields made from heavy-duty 16-gauge steel with 220-degree coverage to prevent blueing. The race version includes a two-step baffle that transitions from 2.5 inches to 3 inches, producing a deep, throaty sound. The kit is complete with all mounting hardware and O2 ports. For 2021 and later Euro 5 models, you will need O2 sensor eliminators and digital tuning to manage the check engine light and ensure the bike runs perfectly.
