Pride Exhaust proudly presents our Pride SUS304 Stainless Steel Header System for the Acura NSX. These are a direct bolt-on for the 91-94 & 95-99 NSX w/ manual transmissions only (includes O2 sensor extension harness for the 91-94 models). Our 91-94 NSX header system incorporates a ball-joint pivot point replacing the flexible coupling used by other brands for their inferior header systems. The ball-joints allow the headers to flex and pivot with engine torque independently from the rest of the exhaust system. The benefit of this ball-joint system is the elimination of the OEM flex joint, which is prone to cracking under stress and over time. Our headers are made from SUS304 stainless steel and comes with stainless steel mesh donut gaskets, flat gaskets, & an O2 sensor extension harness. The collectors feature a 60mm (2.36") inner diameter. These headers will also fit '95-'05 NSX's if installed with our '91-'94 Test Pipes and Exhaust System. Installation on a '95+ NSX will require additional O2 bungs on the test pipes. All PRIDE EXHAUST products come with a 2 year warranty.
