Harley Davidson Street Glide 2009-Up Exhaust Pro Pipe High Output Vance & Hines 47559
Designed specifically to address the needs of tuned motors built for high horsepower applications, Pro Pipe Hi-Output is a purpose-built addition to the Pro Pipe family of 2-into-1 exhaust systems. After countless dyno tests Pro Pipe Hi-Output was built utilizing tuned length headers that step from 1-3/4” to 2” to 2-1/4” with an oversized merge collector flowing into a stepped 4-1/2” megaphone to optimize exhaust gas velocity and scavenging. Pro Pipe Hi-Output for 09-2010 has 4 O2 sensor ports, two near the collector for 2010 models, and two in the head pipes for tuners needing wide band O2 sensor locations. Also included are two sets of O2 sensor plugs. Optional quiet baffles and optional stainless steel heat shields also available.
