New Agency Power catback exhaust system with titanium tips for the Nissan 370Z. Nissan released the 370Z in 2009 as an improved version of the already popular 350Z. Being a performance oriented car, the 370Z was in need of an exhaust with quality, performance and style. Agency Power has met that goal with the full stainless steel catback system ready to bolt on. Constructed with mandrel bent 304 stainless and tag welded ensures a quality product that will last. A dual exhaust with full 2. 5" tubing gives the 370Z more exhaust flow and more power. Finished off with dual titanium tips and included optional silencers, your 370Z will be higher quality, better looking and out perform the others on the road or track. The exhaust system is much lighter then stock as well to keep the 370Z nimble and quick. The exhaust generated good linear power from the mid and top end rpm. Because of the reduction in back pressure, most normally aspirated cars drop low end torque with aftermarket exhausts. A gain of +10hp and +5 ft. lbs of torque were seen on the dyno.
