The name says it all. The Vance & Hines Pro Pipe is the ultimate in performance for your Harley-Davidson Big Twin, period. With over twenty years of evolution in the Pro Pipe, it has all the ingredients for making power; stepped headers, an oversized collector and long megaphone muffler. The latest generation Pro Pipe now features the innovative PCX™ technology, which integrates a chambered high-flow catalyst in the megaphone for a bigger boost in torque and the boneshaking roar of a drag bike racing down the strip.
– PCX™ (Power Chamber Exhaust) technology
– Chambered high-flow catalyst cartridge designed to increase torque
– Stepped headers and oversize collector
– Chrome plated finish
– 49-State Emissions Compliant.
Vance & Hines innovative PCX™ Technology explained: More Power & Less Heat.
The PCX™ (Power Chamber Exhaust) Technology are factually chambered high-flow catalysts. Used to increase mid-range torque for more responsive acceleration off the line. They are positioned downstream for up to 20% less heat at the floorboards / foot pegs and 50% less heat at the collector, to optimize rider comfort over the stock system.
PCX™ technology uses a high-flow double-matrix catalyst that improves torque delivery through the mid-range for more responsive acceleration. All while producing an even deeper full-throated rumble, all with no compromise to the styling of any Vance & Hines exhaust system.
Tech-Tip: Pre-2021 USA mufflers on a 2021-up EU Softail/Touring?
The FuelPak FP4 (part number 942227) allows you to disable the 2nd. O2 sensor in the muffler, or in the balance pipe of the cross-over section, without triggering trouble codes. This will enable you to use exhaust mufflers for earlier/US models that are not equipped with an O2 sensor connection.
