Untd. Performance Catless Downpipe With OPF – Audi SQ8 / RSQ8 | Lamborghini Urus 4.0T

Unlock the true character of your Audi SQ8, RSQ8, or Lamborghini Urus with the Untd. Performance Catless Downpipe With OPF. Engineered for the 4.0T twin-turbo V8, this precision-built performance upgrade retains the factory OPF (Gasoline Particulate Filter) while eliminating the restrictive catalytic converter. The result? Sharper response, enhanced turbo spool, and an aggressive yet refined exhaust note—all without fully removing emissions-related components.

Key Features:

Catless Design w/ OPF Retained

The Untd. Performance Downpipe removes the catalytic converter while retaining the OEM OPF system. This configuration maximizes exhaust flow and turbo efficiency without fully deleting the emissions control system—making it ideal for enthusiasts looking to enhance performance while maintaining a partially emissions-conscious setup. Enjoy significant power gains, reduced backpressure, and an invigorating exhaust sound.

Refined Aggressive Exhaust Note

With the catalytic restriction removed, the V8 engine produces a deeper, more engaging tone that comes alive under throttle. Expect pronounced turbo spool, sharper engine acoustics, and satisfying crackles—while still maintaining a level of refinement courtesy of the retained OPF. It’s the perfect balance of raw performance and drivability.

Noticeable Performance Gains

Thanks to the free-flowing design, turbochargers spool faster, throttle response is more immediate, and power delivery becomes more linear across the rev range. Experience stronger low-end torque and high-end pull—ideal for spirited driving, tuning, and performance builds that don’t require complete OPF removal.

Integrated Heat Shield

A built-in heat shield helps manage under-hood temperatures, protecting critical components from excessive heat and maintaining consistent performance during aggressive driving or prolonged high-load conditions.

High-Quality Stainless Steel Construction

Constructed from premium 304 stainless steel, the Untd. Performance Downpipe offers long-lasting durability and a precise, bolt-on fit. Precision TIG welds and CNC-machined flanges ensure a perfect seal and seamless integration into your vehicle’s exhaust system.

Track-Ready Performance

Designed for high-output applications, this downpipe is perfect for dyno tuning, spirited street driving, and track use in regions where partial emissions systems (OPF) are retained. It strikes a smart balance between performance gains and regulatory consideration.

Compatibility:

  • Audi SQ8 4.0T Twin-Turbo V8

  • Audi RSQ8 4.0T Twin-Turbo V8

  • Lamborghini Urus 4.0T Twin-Turbo V8

If you’re seeking more power and sound without a full emissions delete, the Untd. Performance Catless Downpipe With OPF offers the ideal compromise. With enhanced flow, improved response, and a deepened exhaust tone, it’s the upgrade your twin-turbo V8 SUV was built to handle.
