Transform the sound and character of your Porsche 986 Boxster (1997–2004) with SOUL’s Valved Muffler Bypass Conversion. These direct bolt-on pipes replace the factory exhaust section, delivering a refined OEM note with valves closed and an aggressive, CUP car–inspired roar with valves open. By default, the valves remain closed at startup for a smooth, neighbor-friendly warm-up, and with a press of a button you unleash the unmistakable flat-six tone.
• Fits all Porsche 986 Boxster models (1997 – 2004)
• Valves closed on startup for a quiet, drone-free OEM experience
• Remote valve control included, with compatibility for factory HomeLink buttons (if equipped)
• Designed and hand-built in-house at SOUL’s Willow Grove, PA facility
• Backed by SOUL Performance Products’ Lifetime Warranty for both street and track use
DEVELOPMENT:
SOUL engineered this system to offer the flexibility of two exhaust personalities in one. With valves closed, it’s quiet and refined—perfect for everyday driving or early morning startups. Open the valves, and the mufflers are bypassed to create a raw, motorsport-inspired soundtrack, all while minimizing drone.
SOUND:
Valves closed, your Boxster retains its stock tone. Open them, and exhaust gases flow directly through the bypass tubes, producing an aggressive bark and thrilling flat-six roar that transforms the driving experience.
CONSTRUCTION:
Each system is fabricated in-house using brand new OEM Porsche muffler piping and high-quality, application-specific valves. Exhausts are built in precision aluminium fixtures to guarantee fitment, rigorously tested, and foam-packed for safe delivery.
BOLT ON AND GO:
The design allows for straightforward installation with no cutting or modifications. Simply bolt on and enjoy the ability to switch between OEM refinement and track-day aggression with the included remote valve controller.
LIFETIME WARRANTY:
The design allows for straightforward installation with no cutting or modifications. Simply bolt on and enjoy the ability to switch between OEM refinement and track-day aggression with the included remote valve controller.
