Exhaust heat exchanger fitting kit. Includes studs and nuts made out of titanium.

These titanium components are resistant to rust and corrosion, which can be a common issue with traditional steel studs and nuts. This corrosion resistance ensures that the studs and nuts maintain their integrity, allowing for easy removal and installation when necessary. They are the perfect upgrade for Porsche enthusiasts who demand the ease of access to vehicle's exhaust system.
