Show original supplier description
The Motordyne TDX - 2 Exhaust (MD-004) is a true dual X-pipe exhaust system designed to maximize torque and horsepower for the Nissan 350z and Infiniti G35. This exhaust system strategically employs dual 3.0" primary tubes and dual 3.0" exhaust tubing to deliver significant power gains. Improvements over previous models include the addition of resonator chambers, which effectively reduce drone and refine the exhaust's audible tone. Constructed with a fully polished and TIG-welded finish, this exhaust system is built for durability and aesthetics. It features a V-band flange for secure connection, 2.5" primary tubes, and 3" midpipes. The tips measure 4 inches in diameter. This exhaust system is capable of supporting 650HP+, making it suitable for builds with turbocharger needs.
