The catalytic converters on the stock Nissan test pipes is the same on the 370Z and the 370Z Nismo unfortunately they are not high flow catalytic converters just standard stock OEM ceramic made to Nissan specs. Although the HKS 370Z Nismo exhaust is a upgrade and is less restrictive compared to the stock OEM 370Z exhaust system. Your exhaust note will change some also.
