Borla S-Type II True Dual Catback Exhaust System with Carbon Fiber Tips - 2003-2008 Nissan 350Z 3.5L V6 (140958CFBA)
Unleash the acoustic potential and performance of your sports car with the Borla S-Type II Catback Exhaust System. Purpose-built for the 2003-2008 Nissan 350Z equipped with the 3.5L V6 engine, this high-performance system steps up from previous iterations to deliver Borla's more powerful S-Type II sound profile. It provides a deep, aggressive, and signature sports car growl under acceleration that emphasizes the V6 engine's high-RPM heritage while keeping interior volume levels entirely comfortable and drone-free during daily driving or highway cruising.
This premium system is engineered with an optimized True Dual layout, featuring 2.25-inch mandrel-bent piping that improves flow by 27 percent over the restrictive factory exhaust. The integrated mid-section incorporates an engineered H-pipe to balance exhaust pulses, optimizing scavenging efficiency to deliver independent dyno-proven gains of 15-20 horsepower and torque across the entire RPM range. In addition to performance gains, the lightweight T-304 austenitic stainless steel construction sheds 11 pounds compared to the stock setup. The system exits at the rear bumper with massive, dual 4.5-inch round angle-cut carbon fiber tips with black anodized aluminum centers, providing an exotic, ultra-premium race style. Every connection is CNC manufactured for a secure, factory-style direct bolt-on installation, backed by Borla's comprehensive lifetime Million-Mile Warranty.
