The GReddy GPP RS Race Cat-Back Exhaust for the Nissan 370Z is a light-weight single-exit exhaust system with large diameter piping and is Greddy's most aggressive sounding exhaust for the 370Z. The system includes a high flow Y-pipe that connects both header banks through dual 2.5” (63.5mm) piping that merge smoothly into 3” (76mm) piping. The system exits an extra long, high-flow, RS muffler on the driver-side to manage sound output and avoid having to relocate the EVAP system. Even with the large diameter piping, there is a weight savings over 32lbs compared to the OEM stock system.

**This exhaust system does NOT include a resonator.**

Like all GReddy Revolution RS systems, it is a fully hand-welded 304 Stainless-Steel exhaust, that carries a Limited Lifetime Warranty.

Best exhaust for the money!

Only took about an hour or so to install it in my garage with basic tools. At first thought, I wasn’t pleased because of the drone but after driving it for awhile it’s really not bad at all. Great exhaust and sounds great for just a Catback exhaust! Videos don’t do it justice for sure!
