The Invidia Gemini catback exhaust system for the Infiniti G35 sounds as good as it looks. A full true dual exhaust system, the Gemini features mandrel bent 60mm stainless steel piping and a free flowing oval style sport muffler to provide better exhaust flow for improved performance. Bolting up a Gemini to your VQ will allow your G35's sonorous exhaust note to come through loud and clear when you want it to, without producing harsh or overly loud overtones during regular driving; the perfect choice for those who want great performance with an exhaust note that won't wake the dead. When tested on a bone stock 2006 350z the Invidia Gemini exhaust gained an impressive +21whp and +22wtq! The Invidia Gemini exhaust is available with rolled stainless tips, rolled titanium tips, or slash cut titanium tips.
