Installation

The Invidia INV Gemini is a true bolt-on axle-back exhaust system, designed to replace the factory rear muffler section using existing OEM hangers and mounting points. No cutting, welding, or custom fabrication is required. Most installations can be completed with basic hand tools in 1–2 hours on a vehicle lift or with jack stands. Professional installation is recommended to ensure proper alignment of the titanium tips and a rattle-free fit. Does not require an ECU tune when used as a standalone axle-back system.
