997 S Exhaust |
| |
A stock 997S with it's 3.8 L engine of 355Hp has ø 55mm primary exhaust tubes which is the same size of tubes as the older 996 3.4 L engine with 300 hp. To cope with the additional airflow of the larger 997S engine , our sport exhaust system uses a combination of ø 60.3mm and ø 63.5mm primary tubes. (2 3/8 inch and 2 1/2 inch) |
|
 |
| |
The stock 997S headers have ø 42mm
tubes. Both the 997S X51 and 996 GT3 headers
have ø 48mm tubes. We have build and tested
several equal length headers in both 45mm , 48mm and 50mm
tube sizes. Eventually the OEM X51 headers turned
out to equally good but without having the inevitable ground
clearance issues. |
|
|
| |
Our 997S sport exhaust system consists of: |
|
|
| |
- 1 set sport mufflers
- 1 set sport catalytic convertors with 100 cells per square inch
- 1 set OEM X51 headers
- 4 sets exhaust clamps
- 2 tube clamps to hold the catalytic convertors
- 1 set modified chromed OEM dual tailpipes (optional 1 set modified chromed equipment 997 Carrera oval tailpipes)
- bolts and gaskets

| |
Power gain is 16 hp and 18 Nm / 13 Lbs ft. |
|
|
| |
There is lots of torque down low and the throttle response is phenomenal. There is no droning while cruising and no droning during acceleration. Our 997S sport exhaust system must be used with the stock air intake housing and the stock air cleaner. |
|
| |
It took us 10 months and 8500 km of testing on our own 997S to get these results. We used a Maha dyno and 2 different Bosch dynos during the development. This is our best performing exhaust system since we started building 911 sport and race exhaust professionally about 18 years ago. |
