This is a high-grade lightweight titanium system, finished with hand-crafted carbon-fiber tailpipes and a high-grade austenitic stainless steel link pipe set. The valves on each side are calculated to tailor the sound, and two acoustic reflectors are fitted on the tailpipes to guide the sound into the car’s cabin. Because the Akrapovič Evolution Line (Titanium) exhaust system has two valves, one more than the stock configuration, a TNG controller is included in the product to activate the additional exhaust valve. To make the sound experience even more unique, there are two tuned resonators – developed especially for this new engine – producing a deep, rich, and sporty sound with no unwanted drone or streaming, perfectly aligned with the straight six-cylinder engine. It weighs 21.7 kg, which is 23% lighter than stock. Power gains of 11.8 hp at 5,600 rpm and torque increases of 17.1 Nm at 4,100 rpm were recorded when tested on the Akrapovič dyno

Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience.
