Show original supplier description
The Flashark 4.5-inch Single Tip Catback Exhaust system is engineered to enhance the performance and sound of your 2003-2008 Nissan 350Z or Infiniti G35. Crafted from durable SUS-304 stainless steel with a mirror-polished finish, this exhaust is designed for long-term use and resistance to corrosion. This catback system features 3-inch piping and a 4.5-inch single tip, complete with a detachable double-layer silencer. This allows for customizable sound, from a refined tone for daily driving to a more aggressive roar for spirited driving. The direct bolt-on design simplifies installation, and all necessary gaskets, bolts, and nuts are included, making it a straightforward upgrade for enthusiasts with basic tools. Performance gains are expected, with an average increase of 10-15 horsepower and improved throttle response due to reduced backpressure. **Fitment & Compatibility Notes:** * This exhaust is absolutely NOT compatible with Infiniti G35 Sedan models. * An Extension Pipe is REQUIRED for all 2003-2008 Infiniti G35 Coupe models. * Verified fitment for Nissan 350Z (2003-2008, 3.5L VQ35DE V6 Engine; Coupe & Convertible) and Infiniti G35 Coupe (2003-2008, 3.5L VQ35DE V6 Engine with Extension Pipe).
