The Screamin' Eagle® High-Flow Exhaust system provides bolt-on performance by reducing catalyst restrictions and improving exhaust flow. Optimized for CVO 110 and Screamin' Eagle® Stage Kit engine configurations producing 80-100+ HP, the kit replaces the stock head pipe and mufflers with large diameter free-flowing head pipes and matching mufflers. The muffler inlet diameter has been increased to 2.25" to enhance exhaust gas scavenging and the catalysts have been relocated to the mufflers to enhance flow. This system can produce 5-7 hp gains on a 110ci motor and 8-10 hp gains on a 120ci motor when compared to the Original Equipment exhaust system. Extra oxygen sensor bungs permit attachment of tuning equipment. Kit includes head pipe, 2.25" inlet Nightstick mufflers with catalysts and a collector and crossover tube heat shield. 50-state legal.
