The NOVITEC 849 Testarossa Race Exhaust removes flap-regulation entirely, giving the 4.0L twin-turbo V8 a fixed, open exhaust note at every RPM. It’s power-optimized and fully heat protected for sustained track use. You can choose stainless steel, lightweight Inconel, or Inconel with 999 fine gold plating for extra heat reflectivity, with tailpipes available as an option.

Requires the NOVITEC GTRONIC to prevent error indications from the gasoline particulate filter (GPF)

Requires the NOVITEC NOVITRONIC for exhausts without flap-regulation to avoid diagnostic errors

If you are purchasing this exhaust system in combination with the Sport Downpipes, then NOVITEC’s GTRONIC and TECTRONIC are also required in combination to avoid error indication

Tailpipes are not included with this system; they are optional at the time of order or available separately
