Amplify your ride with the Indian Motorcycle Thunderstroke & PowerPlus Stage 1 Slip On Exhaust, precision-tuned to produce a rich, deep rumble at low RPMs and a bold, full-throated sound at higher speeds. This high-performance dual exhaust system reduces backpressure and improves airflow from header pipe to tip—helping your engine breathe more freely and unlocking increased power, stronger mid-range torque, and a sharper, more responsive throttle feel. 

Designed to integrate seamlessly with your Indian Motorcycle’s hard saddlebags, this system completes your custom look with your choice of exhaust tips (required, sold separately) for a bold, factory-custom finish. For maximum performance and an even deeper intake tone, pair it with a Stage 1 Air Intake (sold separately) to complete your full Stage 1 upgrade. 

This high-performance motorcycle exhaust kit includes two (2) heavy-duty exhaust slip on pipes, installation hardware, step-by-step instructions, and a calibration card with a unique ECM update code. Dealer installation is required to apply the ECM software upgrade and ensure optimal performance.

Signature Sound Upgrade: The Indian Motorcycle Thunderstroke & PowerPlus Stage 1 Slip On Exhaust delivers a rich, deep rumble at low revs and a bold, full-throated sound at high revs—amplifying your ride’s auditory presence. 
Performance Gains Across the Powerband: This high-performance dual exhaust kit helps your engine breathe more freely—unlocking increased power, stronger mid-range torque, and sharper throttle response. 
Factory-Custom Finish with Interchangeable Tips: Choose from a variety of exhaust tip styles (required, sold separately) to personalize your performance exhaust system and achieve a bold, factory-custom look. 
Enhanced Intake Tone When Paired with Stage 1 Air Intake: Combine with a Stage 1 Air Intake (sold separately) for a deeper, more aggressive intake note and a more immersive riding experience. 
Stage 1 Synergy: Engineered for seamless integration with a Stage 1 Air Intake, this system maximizes airflow, tone, and overall performance across your complete Stage 1 upgrade. 
What's Included: A pair of heavy-duty OEM slip-on exhaust pipes, a calibration card with a unique ECM update code, installation hardware, and step-by-step instructions.
