SOLD
Excellent condition, personally tested for 50 miles on a low mileage 1997 986 we had. This will fit all 1997-2002 Boxster/Boxster S. **On 1997-1999 Boxster you will need additional bracket to install (we have them).
The valves stay open when not hooked up. We do not have the associated vacuum cannister/unit to operate the valves, which basically closed the valves under 3k RPM or between 20-45 MPH for sound emissions reasons etc.
The kit part number for this exhaust was 00004420012 (000-044-200-12)
The part number on the muffler assembly itself is 99611198700 (996-111-987-00)
