A client of Ageny Power was kind enough to document their install of the Hyundai Genesis exhaust for the 2.0T and send it to us to share with all of you.

A quick tip for removing the stock exhaust for faster install is to unbolt the cat-back from after the 2nd Catalytic Converter, unbolting the cross brace under that smashed area of the exhaust, and then remove the exhaust hangers.

Below are pictures of the install with a nice YouTube video of the sound after install.
