First, it is made of high-quality stainless steel T304, which is durable, corrosion-resistant and lighter than bulky OEM exhaust. The exhaust pipes are cut with 3D technology and welded by hand with TIG welding technique, ensuring a flawless finish and a distinctive texture. Each pipe from Fi is hand polished both INSIDE and outside to present the most exquisite appearance and truly unobstructed airflow.

Secondly, Fi EXHAUST system for Mercedes G63 has a valvetronic function that allows you to control the sound level of your exhaust with a remote or an app on your smartphone. With Fi Pro you can choose between three modes: Street mode for cruising around town, Race mode for unleashing the full potential of your engine and Auto mode for intelligent valvetronic control. The valvetronic function also improves the performance of your G63 by optimizing the airflow and reducing back pressure.
