A representative project for a future classic car. This car’s exhaust system had some heavy issues that the maker never solved, like the frequent failure of the manifold, and some others.
The Supersprint rear silencer has an insulating double wall envelop, drilled and curved pipes and a resonator.
The custom headers with single independent pipes have a 4 in 1 design with merging elements using a patent system by Supersprint, “floating flange – trochoidal gasket – retaining springs”.
This exclusive design leaves the single pipes free to expand, removing any structural stress and any possible breaking cause.
There are new heat shields, placed in critical spots, on thermal stressed elements only.
Each OEM manifold instead is completely covered in a big insulation box; this gives effective protection to the components surrounding the exhaust, but uselessly increases the thermal load on the exhaust pipes, supposedly becoming the cause for the frequent failure of them.
The custom metallic catalytic converters have been developed to optimize the performance and to allow the removal of the complex OEM multiple cat system, not great in terms of efficiency. This presented a bypass valve, an obsolete system that even the maker abandoned in the next model, the 360.
The combination of these three exhaust components developed by Supersprint, rear exhaust + catalytic converters + headers, produces a sensible performance gain at all rpm, and increases durability and reliability at the same time.
