Audi SQ8 in for a Full Fi Exhaust System and a Custom Dyno Tune

We recently had this blacked out Audi SQ8 in for a full exhaust and a custom dyno tune. The customer decided on a full valved system from Fi that retains the factory drive mode valve control. The Fi system is known for its increased volume and refined tone, but the customer was not stopping there. He decided to take it a step further with a Westtuned Custom Dyno Tune and squeeze some additional power out of his 4.0t.
