89mm + 2 x 63,5mm sport exhaust system after cat.
End pipe: 4x90
BSR SportFlow exhaust systems meet the requirements for performance and durability and have several advantages:
- Fits directly into the vehicles 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.
- Non-corrosive materials, chrome steel and 18/8 stainless steel for long durability.
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
Catalytic converter, down pipe, flexible parts and pipes in the engine room are not included in the SportFlow kit. See Stage 3 and down pipes for complements.
*) Some exhaust systems and suspensions may need modifications and supplements, for example for duplex systems. More information can be found for each system.
BSR Sportflow comes with a three-year general warranty and a extended five-year corrosion warranty.
This extended warranty includes failure due to corrosion that passes 'through' the metal and results in a blow or fracture.
Turbo- down pipe
For some turbo vehicles the BSR 3" sport catalytic converter down pipe is available. This will give further power benefits and higher boost pressure and a wider boost pressure range. The BSR down pipe must be combined with the BSR sport system and BSR Step 3 software.
Regarding RHD vehicles
Generally our parts, such as exhaust systems, frontpipes and Opti Flow-kits are developed for LHD cars. Some of them could also fit RHD cars, but we have no possibilities to test this.
