Rear exhaust Right - Left "Sport" + Metallic catalytic converters

High performance sport exhaust for Porsche 997 Turbo 3.6 "Sport" version

Composed by:
- 2x HJS High-Volume Dual Metallic catalysts (http://www.hjs-tuning.de/en/3/105/0/seite_1/Technics/Sport-Catalytic/sport_catalytic.html).
- Rear direct flow design silencer with internal x-pipe
- 2x70mm oversize bore

CAUTION: because the OEM catalytic converter are replaced it may cause the triggering of the Check Engine Light caused by an O2 sensor error.
ECU tuning is recommended.

Thanks to the reduced backpressure compared to the OEM unit this component allows for a quicker turbo spool up and a consistent power and torque increase in the whole rev range.
The sound is sportier but not extreme, for daily road use and long trips.

It must be fitted with Supersprint tailpipes or connecting pipes for OEM tips.

Perfect fit without any mechanical modification.
