Redstar's downpipe and exhaust system for the Acura NSX (NC1, 2016-2021) and NSX Type S (2022-2023) is built in two steps: the downpipes first (or keep the OE downpipes), then the valve-delete exhaust.
Key Features
- Step 1 - Downpipes: HJS HD 200cpsi 130 mm or GESI GEN2 UHO+ 400cpsi 5" catted, or catless, each with or without a heat shield
- Step 2 - Exhaust: Dual or quad tip, stainless steel or titanium, with heat-shielded stainless steel options
- 100% bolt-on, no cutting or fabrication; the exhaust uses OEM-spec flanges and works with OE or aftermarket downpipes
