Metallic catalytic converters, with 100cpsi monoliths
The front section of the Supersprint exhaust uses 2 Metallic catalytic converters with 100cpsi rating, one cat each side. The stock system, on the contrary, uses a total of 4 cats (2 cats each side), 2 of them (1 each side) are positioned very close to the cylinder heads, and their rating is 400cpsi or higher.
This design has the sole purpose of providing a shorter warm-up time during the cold start phase, but at the same time it severely restricts the exhaust gas flow and compromises on the performance of the engine. The Supersprint cats, made in Germany by HJS- Emitec, the world leader in technology for performance, Metallic catalytic converters, are positioned further downstream in the exhaust system, have a much lower 100 cpsi rating, and use oversize, 63.5mm piping before and after the cats.
The merging cones are Supersprint’s own design components, and they are designed to offer the smoothest transition from the pipes to the cats. These features guarantee a dramatic reduction of the exhaust gas backpressure, and also allow for a lower operating temperature in the head exhaust ports' area, when under a load, especially at medium and high rpm.
This Supersprint exhaust component uses before-cat and after-cat Lambda sensor ports, and is totally compatible with the car's own OBD II emission management system. It is also available in the non-cat, straight pipe version, upon special request, for closed-course, track-only use, wherever the race sanctioning body regulations allow it.
Headers
The key component of the Supersprint E 500 exhaust, instrumental to best performance, is the headers. These very special headers have been designed and developed by Supersprint' own R&D team, and they have been extensively tested on Supersprint own MAHA braked dynamometer.
While the stock headers use an ineffective log design, with extremely short, restrictive runners, made out of stamped, metal halves, the Supersprint headers feature long, 42mm o.d. tubular, individual primaries, mated together smoothly, thanks to the special, 4-1 Supersprint 63.5mm merge collector design.
As a comparison, the stock headers and the inlet pipe leading to the cats have a main section of only 46mm, this means that the Supersprint headers have a 73% wider cross-section in this particular, most critical area.
At peak rpm, the exhaust backpressure the Supersprint system is just under .17 bar, a key recipe for making the best performance, while the stock system has 42 bar. This 60% reduction of backpressure immediately translates into lower exhaust gas restriction, better flow and stronger performance at all rpm. A result this good cannot be achieved by any cat-back exhaust only, no matter which design and pipe size it’s made with. This is the only reason why Supersprint develops and produces full headers systems, as they are the only way possible to real, solid increases in performance. Everything else available on the market is made mostly for sound and looks. Also, the Supersprint patented multi-piece pipe headers design allows for an easy fitment process, which does not require lifting the motor from its mounts. This headers only fits the left hand drive E model.
