Irish Pig Performance 2-into-1 Harley Davidson Low Rider S Low Rider ST

IRISH PIG PERFORMANCE 2-INTO-1  HARLEY-DAVIDSON LOW RIDER S  Low Rider ST

Built for Harley-Davidson Low Rider S and Low Rider ST riders looking for a performance 2-Into-1 exhaust with strong torque, responsive acceleration and horsepower that carries through the upper RPM range.

Each Irish Pig Performance exhaust is hand-fabricated from premium stainless steel and TIG welded with full back-purging for clean, high-quality internal welds and unrestricted exhaust flow.

CONSTRUCTION & DESIGN

• Hand-fabricated stainless steel construction

• Stepped 1.750” → 1.875” → 2.000” primary tubes

• Custom-fabricated 2.000” → 2.500” merge collector

• 18-degree merge angle

• 12” performance muffler

• TIG welded with full back-purging

• Designed and fabricated in Henderson, Nevada

O₂ Sensor Compatibility: Supplied with 18mm O₂ sensor bungs for wideband sensors and 12mm reducer bushings for narrowband sensors

The stepped-primary design and merge collector are engineered to promote efficient cylinder evacuation and exhaust scavenging. The system is designed to provide strong low- and mid-range torque while maintaining the flow capacity needed to support horsepower at higher RPM.

This exhaust is well suited for stock-displacement Milwaukee-Eight engines as well as performance combinations using aftermarket camshafts, cylinder-head work, increased compression, larger throttle bodies and other supporting modifications.

Final performance will depend on engine combination, fuel management and proper calibration.
