2003-2009 INFINITI G35 Coupe Dual / Nissan 350Z 4.5" Tip Muffler Catback Exhaust System

Upgrade your vehicle's exhaust system to unleash hidden power and transform its performance. A well-designed performance exhaust system—featuring larger piping, high-flow mufflers, and precision-tuned resonators—dramatically reduces backpressure and unlocks horsepower and torque stifled by factory restrictions. The result? Stronger acceleration, improved throttle response, and an aggressive, refined exhaust note that elevates every drive. body { font-family: Arial, sans-serif; line-height: 1.6; margin: 20px; background-color: #f9f9f9; color: #333; } .container { max-width: 800px; margin: 0; background: white; padding: 20px; border-radius: 8px; box-shadow: 0 0 10px rgba(0,0,0,0.1); } h1 { color: #2c3e50; margin-bottom: 20px; padding-bottom: 10px; } .specs-table { width: 100%; border-collapse: collapse; margin: 20px 0; } .specs-table td { padding: 12px 15px; border: 1px solid #ddd; } .specs-table tr:nth-child(even) { background-color: #f8f9fa; } .specs-table tr:hover { background-color: #f1f1f1; } .spec-name { font-weight: bold; background-color: #f5f5f5; width: 30%; } .spec-detail { width: 70%; } Features Inlet / Outlet Diameter 2.25" / 2.25" Tip Diameter 4.5 in Design High Performance Racing Design Catback Exhaust System Material Made of High Quality Stainless Steel with Computerized Mandrel-Bends for Strength and Durability Fitment Direct Bolt-On Fitment; No Modifications Required Performance Increases 10 -20 Horsepower/ Low End Torque Flange TIG Welded CNC Machine Flange for Resistance against Pressure and Corrosion Sound Aggressive Deep Sound while Ensures Smooth Exhaust Gas Flow Efficiency Increase Engine Output and Efficiency Installation Professional Installation Recommended Fitment: Vehicle Model Years Engine Nissan 350Z 2003-2009 3.5L Infiniti G35 Coupe 2003-2007 3.5L
