The triple tip Invidia Gemini R400 exhaust system features a single layer style tip exhaust for a robust and aggressive look. This model features a titanium 4-inch burn tips for that race inspired look. The R400 for the 2017+ Honda Civic Type R features independent muffler resonators for each tip to reduce weight and provide a deeper exhaust tone.
In order to create a true 3-inch cat-back, Invidia decided to include the down-pipe/mid-pipe/front-pipe with this system. Meaning this system connects all the way up to the primary down-pipe making this a true 3-inch exhaust system!
