Show original supplier description
The Motordyne Shockwave TDX2 is a performance-oriented cat-back exhaust system designed specifically for the Infiniti G35 Coupe. By utilizing a true dual X-pipe configuration with progressively expanding 2.5-inch primary tubing that flows into 3.0-inch exhaust pipes, this system is optimized to improve the overall power and torque output of the VQ35 engine. The design incorporates resonator chambers specifically tuned to reduce cabin drone during cruising speeds, while still producing a signature, aggressive exhaust note under hard acceleration and high RPM conditions. The system is a direct bolt-on replacement that is compatible with factory catalytic converters. It comes standard with 4.5-inch exhaust tips available in either stainless steel or burnt titanium finishes. Please note that this is a performance component and, in some configurations, may be part of a larger 600+ HP capable system.
