Built for Real Power, Without the Compromises - Tested and validated to deliver reliable performance without concern for premature failure.

Once you move past a basic tune on the 4.0T, you're asking a lot more from the factory cats — and honestly, they just can’t keep up. We’ve seen it time and time again: stock converters break down under the extra heat and pressure, and when they do, the risk isn’t just poor performance — it’s engine damage.

We decided to build something better. Something we’d actually run on our own cars — and trust over the long haul.

Engineered for Endurance, Guaranteed for Life

We understand that a lifetime warranty offers little value if you're frequently dealing with the inconvenience and expense of part replacement and re-installation labor. At Vorsprung Autowerk, our focus isn't just on warranty duration; it's on product longevity and reliability.

We chose our materials and design specifically to eliminate the common failure cycle of 12-24 months. Our components are built right the first time to stay on your vehicle.

We provide a Lifetime Warranty because we are confident you won't need to use it.

Performance, Reliability, and Thoughtful Design

Full flow path from top to bottom, with no tapering down to OEM size
Smooth transition to OEM-style lower flanges for easy fitment
Vorsprung reinforced flange design
Precision TIG-welded and back-purged for maximum strength
Double-walled pipe ends to resist cracking over time
Extra-thick 10mm stainless flanges, reinforced inside and out to prevent warping and treated for an ultra smooth mating surface
Heat shielding included to control temps, reduce heat soak, and protect nearby components
304L stainless steel construction (Vorsprung Spec 2.0mm wall thickness) throughout — built to last

And for peace of mind? You get a an unlimited-launch warranty against catalyst failure. Go ahead — drive it like you mean it.

Please note: These are made to order. Delivery times are approximately 30 days.
