Borla S-Type Classic True Dual Cat-Back Exhaust System (140045) - 2003-2008 Nissan 350Z 3.5L V6
Wake up the adventure-ready spirit of your rig with the high-impact Borla S-Type Classic True Dual Cat-Back Exhaust System. Custom-engineered exclusively for 2003 to 2008 Nissan 350Z models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the S-Type Classic sound level. Formulated explicitly for sports car purists and track day enthusiasts who crave an aggressive, throatier exhaust note under acceleration without being overbearing, this system is calibrated to give the 3.5L V6 engine a deep, resonant growl. This true dual cat-back configuration provides an optimized, race-inspired exterior presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during daily commuting, long highway drives, or canyon carving.
The internal engineering of the Borla 140045 targets key factory flow restrictions by incorporating an upgraded high-efficiency layout that channels a 2.25-inch diameter path through ultra-smooth mandrel bends and an integrated H-Pipe assembly to maximize exhaust velocity, scavenging, and cross-bank balancing. Independent dyno testing has shown significant gains of 15 to 20 horsepower and torque across the entire RPM range, rather than just shifting power to the top end. This lightweight, premium system delivers a massive 27 percent flow increase over stock hardware while weighing 12 pounds less than the bulky factory single-muffler setup. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable system defends permanently against structural degradation, track-day heat cycling, and corrosion. The spent exhaust gases exit through a stunning dual split rear configuration featuring two massive 4.5-inch round, phantom-style rolled-edge angle-cut polished T-304 stainless steel tips. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting points and is backed by Borla’s legendary lifetime Million-Mile Warranty.
Chassis & Configuration Notes: This cat-back system is engineered specifically for the 2003-2008 Nissan 350Z generation powered by the 3.5L V6 engine (covering both VQ35DE and VQ35HR platforms). It is fully compatible with both Automatic and Manual transmissions and fits 2-Door Coupe and Convertible Rear-Wheel Drive (RWD) models. It is not intended to fit Infiniti G35 chassis layouts or later 370Z body configurations without custom mid-pipe fabrication.
