Having seen one set up on dyno day the supersprint centre and rear back box, managed to put an extra 5kw @ the wheels on dyno on a clio 172. I understand there is a restriction problem from the cat back on the 172 and hence changing this with this type of set up brings it upto the 182 status with a little bit extra.
Supersprint is also offering stainless steel centre and rear exhaust for the 180.The set up of the back box is similar to the stock box but alot smaller as is the centre exhaust.
Has anyone had any experience with supersprint, doesnt necessarily have to be a 180. I have sent off a email to company asking to provide dyno figures, awaiting there reply.
Here are some pics and some notes on the 180 setup
- Extensive road and dyno tests.
- Maximum performance increase (higher torque and peak horsepower output).
- Stainless steel manifolds, free-flow silencers, for lower backpressure.
- E.E.C. homologation.
- Sport sound, innovative design in tail pipe styling.
Edit, dyno of a supersprint system on BMW thats has impressive improvement in torque, also very loud
