The Pride Exhaust Test Pipes for the Acura NSX are direct bolt-on for all 91-94, 95-99, 00-01, & 02-05 NSX’s. Our straight test pipes weigh just under 7-9 lbs/pair. These do replace your catalytic converters. Our Pride Exhaust system is a pretzel-style exhaust, giving the NSX a high-pitched tone and creating performance pushing back-pressure, therefore our exhaust system loves test pipes. These test pipes will give your full system a slightly higher-pitched tone and improve net system horsepower. 97+ NSX will require a CEL Fix for prevent Check Engine Light (Sold separately for $90 additional). For off road use only.
