SOUL Performance Valved Exhaust System for 4S Audi R8

SOUL Performance Products’ Valved Exhaust System for the 2020+ Audi R8 delivers the race-bred V10 soundtrack the car deserves while preserving true dual-personality manners, routing gases through full 3″ T304L stainless piping for an intense, crackling roar with the valves open, or through a bespoke SOUL chambered muffler with an internal X-pipe for enhanced tone with minimal drone when closed. Built in-house at SOUL’s Willow Grove, Pennsylvania facility from mandrel-bent .060″ wall T304L stainless with CNC-machined flanges, back-purged TIG welds, and thick-gauge aluminum fixtures for precise, warp-free fitment, the system sheds roughly 34.1lbs over the factory rear section, sharpening response and reducing weight. Thoroughly quality-checked, foam-packed for safe shipment, and backed by Soul Performance Products’ Lifetime Warranty, it transforms the R8 into a car that can be refined and discreet on command, or unapologetically aggressive at the touch of a button.

Research & Development

• The original factory exhaust system exceeds a weight of 58lbs and incorporates several chambers, but it fails to deliver an authentic, race car-inspired exhaust note. One of their standout exhaust offerings is the Audi Race Exhaust System, which has gained immense popularity due to its unmatched V10 roar. They have received requests to develop a muted system that can reproduce the same captivating sound while providing a more refined option at the touch of a button.
• Their objective is to enhance the presence and character of the exhaust note within the cabin while ensuring a reasonable level of resonance and drone in both the valves closed and open modes. This is achieved through their renowned drone fighting capabilities, which have become their signature. Remarkably, this innovative system manages to reduce the weight by over 34lbs, further enhancing the vehicle’s performance and agility.
• When the valves are closed, the exhaust system is directed through a custom-designed SOUL chambered muffler, featuring an internal X-Pipe that perfectly aligns with their sound objectives. This exceptional muffler has been meticulously crafted to uphold their esteemed reputation for creating mufflers that effectively combat drone issues, a trait well-known in the Porsche community. While they also tested a more traditional muffler design with a perforated core, the carefully engineered chambers of the final muffler deliver a more aggressive sound during both acceleration and deceleration, effectively minimizing undesirable tones.
• With the valves open, the exhaust flow is unrestricted, allowing it to exit through 3″ piping, resulting in a thunderous roar. Secondary flow through the muffler and X-Pipe diminishes raspiness and refines the exhaust note, producing a higher-pitched and more sophisticated sound. The outcome is the realization of two distinct and enjoyable sound modes, a mild option and a wild one.

Construction

• Every system is meticulously crafted using mandrel bent T304L stainless steel tubing with a robust .060″ wall thickness. CNC machined flanges and laser-cut brackets are employed to guarantee precision and durability. Back purged TIG welding, utilizing ARCAL Prime argon gas, ensures optimal weld penetration and longevity. The water jet cut flanges adhere to ISO 9001:2015 standards, exhibiting exceptional precision with tolerances of +/- 0.003 inches.
• To maintain utmost accuracy, they fabricate each exhaust using thick gauge aluminum fixtures. These fixtures not only act as efficient heat sinks during the welding process but also safeguard against warping, ensuring perfect fitment for both their products and the fixtures themselves.

Sound

• Envision the Audi R8’s already powerful note amplified twofold. This exhaust system unleashes an impressively loud and aggressive sound, provoking crackles and burbles that resonate from afar. When seeking a more refined experience within the cabin, simply switch modes to close the valves, allowing for a quieter yet still thrilling journey, with minimal drone disturbance.

Bolt On & Go

• Prior to shipping, each individual component undergoes rigorous quality checks to ensure its impeccable condition. To further safeguard against any potential damage during transit, they are meticulously foam packed, guaranteeing that they arrive in perfect condition.
• Moreover, they provide everything necessary for a comprehensive installation, leaving no essential components or accessories behind. With their commitment to delivering a hassle-free experience, you can rest assured that all the required items are included to facilitate a complete installation.
