Hi,
This is only applicable with the Sport Exhaust System - option code XLF. The sound behavior of the system is controlled as a function of the vehicle speed. The sports exhaust system has two extra exhaust passageways which are opened and closed by control flaps. The flaps are activated by means of a control unit, which receives a speed signal from the speedometer. This exhaust system produces a sporty, powerful sound when both flaps are open. Visible differences between the sports exhaust system and the standard exhaust system are:
- Visible merging of the exhaust pipes below the rear bumper cover.
Eccentric double tailpipe with extra ports.
The exhaust pipe is made from polished, stainless steel. The engine power and exhaust behavior of the car is not affected. The system is fully described in TSB 2/00 2 2601.
This is an optional system and not too common. It resembles the 'S' exhaust in that it also has two tips, but it is not the 'S' exhaust, it is optional and involves installing a Control Unit, a vacuum tank (for the actuator valves) and an extra wiring harness. It also resembles the aftermarket tuned exhausts you find on eBay where the extra tubing is welded to the muffler body of a used exhaust and routed directly to the exhaust tip. Hope this helps...
Happy Motoring!... Jim'99
