Invidia 08+ Subaru WRX/STI 4dr N1 Twin Outlet Single Layer Tip Titanium Cat-Back Exhaust

Invidia is well-known for creating performance exhaust systems that enhance both the sound and performance of Japanese sports cars. This N1 cat-back exhaust system is specifically built for the 2008-2014 Subaru Impreza WRX and STI 4-door models, and also fits the 2009-2013 Subaru Forester. It's designed to replace the restrictive factory exhaust from the catalytic converter back, allowing your engine to breathe more freely.

Constructed from titanium, this exhaust system is notably lightweight, which can contribute to a better power-to-weight ratio. The titanium also offers excellent corrosion resistance. The N1 series is recognized for its aggressive, sporty exhaust note, giving your Subaru a distinct sound that lets everyone know it's performance-oriented. The twin outlet design with a single layer titanium tip gives it a unique look that complements the sporty nature of these vehicles.

This cat-back system is a direct bolt-on replacement for your stock exhaust, meaning no welding or cutting is required for installation. While it's designed to bolt up to the factory catalytic converter, for optimal performance and sound, many enthusiasts pair this cat-back with an aftermarket high-flow catalytic converter or a cat delete pipe, though this may affect emissions compliance. You'll notice an improved throttle response and a more pronounced exhaust tone that is deeper and more resonant than the stock system.
