Invidia 2015+ Subaru WRX / STI Gemini/R400 Single Layer Quad Stainless Steel Tip Cat-Back Exhaust

What you get with this Invidia Gemini/R400 cat-back exhaust system is a complete package designed to bolt directly onto your 2015-2020 Subaru WRX or WRX STI. This system replaces the factory exhaust from the catalytic converter back, featuring a dual-muffler design and quad exhaust tips. It's built from durable stainless steel, which helps resist corrosion and ensures it holds up well over time. The single-layer construction of the tips means they are lighter than multi-layer designs, contributing to a more performance-oriented setup.

The Gemini/R400 system is engineered to give your WRX/STI a more aggressive exhaust note without being overly raspy or droney, aiming for a sound that complements the car's sporty nature. You can expect a noticeable change in exhaust tone, often described as deeper and more pronounced than the stock system. The quad stainless steel tips add a distinct visual upgrade to the rear of your vehicle, giving it a more customized look. Installation is designed to be a direct bolt-on process, meaning no welding or cutting is typically required, making it a straightforward upgrade for many DIYers or a quick job for a mechanic.

When installing this cat-back exhaust, it's a good idea to have a helper, as some sections can be a bit unwieldy. Ensure all hangers are properly aligned and that the system has adequate clearance around the chassis and drivetrain components before tightening everything down. This Invidia exhaust is a popular choice for WRX/STI owners looking to enhance both the sound and appearance of their car.
