Mid muffler (decat)

For the dedicated enthusiast, removing the factory catalytic converters is a optional step to unlocking the NSX's full performance potential. However, a simple straight-pipe replacement often results in sound levels that exceed the strict noise regulations at many circuits, putting your track day at risk.

Racing Factory Yamamoto has engineered the definitive solution. This Circuit-Spec pipe features a high-flow, 50mm diameter stainless steel construction with an integrated, high-temperature resonator (silencer). It is designed to provide the significant performance gains of a decat pipe while strategically reducing overall decibels to help you pass the sound check. It's the key to running your car in its most aggressive state, without compromise.

Engineering & Performance:

• Track Regulation Compliant: The integrated silencer is specifically designed to curb peak volume (dB) without creating excessive backpressure, preserving engine performance and helping you meet noise limits.
• Unlocks Performance: Deletes the heavy and restrictive factory catalytic converters for a significant improvement in exhaust flow, throttle response, and power.
• Durable Construction: Fabricated from high-grade, 50mm (50ϕ) diameter stainless steel for exceptional durability and resistance to high-temperature track use.

Critical Fitment Advisory for NA2 Owners:

Please be aware of the following specific fitment requirement: If you are installing this pipe on an NA2 vehicle (1997-2005) that is equipped with an NA1-type (1990-1996) exhaust manifold, modification to the O2 sensor bung on the pipe may be necessary for correct sensor placement. We strongly advise confirming your vehicle's specific exhaust manifold setup before ordering.
