N1 Cat-Back Exhaust System

The Invidia N1 Stainless Steel Tip Resonator is a high-performance cat-back exhaust system specifically engineered for the 2008-2011 Subaru Impreza 2.5i Sedan, including the 2.5i Premium Sedan and Outback Sport Sedan models. Crafted from premium 304 stainless steel, this exhaust system features 63mm (2.5 inch) piping and a single stainless steel tip. Its design focuses on optimizing engine performance by reducing back pressure and turbo lag. This reduction in restriction leads to enhanced throttle response, an increase in horsepower and torque, and overall improved performance. Beyond performance gains, the Invidia N1 system offers a significant weight reduction compared to the stock exhaust and provides a more aggressive, sportier exhaust note. The meticulous engineering behind Invidia exhausts aims to strike a balance between exhaust back pressure and gas velocity to maximize power output across the entire rev range, ensuring durability and optimal function.
