The Ark Performance GRiP exhaust for the 2018+ Genesis G70 3.3T is designed and engineered right here in Southern California. 

Awesome details include:

• Helmholtz Technology - Reduces Drone to a minimum without sacrificing performance
• T304 Stainless - No thin, unreliable exhaust piping and flanges 
• Mandrel Bent - Smooth bens = more power. The only way to make an exhaust 
• Signature X Pipe Design - Proper design leads to more power and not a choke point
