Simons 2,5" Sport Flow Exhaust Aero/Viggen Saab 9-3 '99-'02

2,5" Sport exhaust system after the catalytic converter Saab 9-3 Aero and Viggen

Sport Flow exhaust systems meet the requirements for performance and durability and have several advantages:

- Fits directly into the vehicle’s original suspensions
- Perfect fit, fast and simple installation.
- A lower back pressure gives less resistance.
- Exhaust gas is evacuated more efficiently and throttle response is quicker
- Sporty acceleration sound. Sound level inside vehicle hardly changes.
- Enhanced appearance thanks to larger, stainless steel tail pipes.
- “Duplex” (double exhaust pipes) for some vehicle types. See vehicle type and year for more information.
- Non-corrosive materials, chrome steel and 18/8 stainless steel for long durability.
- Special non-corrosive clamps included.


For turbo vehicles:
- Quicker turbo spool up
- Boost pressure is maintained during longer intervals
- Improved performance during several accelerations
- Less temperature increase during high loads
