As an alternative to the "road" catted version (987311) Supersprint also offers a de-cat option, for track use.

This component drastically reduces the back pressure after the turbocharger, with beneficial effects on the temperatures and the gas flow.

The absence of the catalytic converter requires the modification of the electronic management to avoid warning lights on the dashboard (CEL).

All the characteristics of the 987311 (easy fit, durability) remain unchanged.

For racing use only
