MERCEDES R230 SL 55 AMG Facelift V8 Kompressor '06 ->'08

Rear Mufflers

Made as the result of a tedious development and testing process, the Supersprints R & L rear mufflers use the Free-Flow design typical of all of the Supersprint performance systems.
Contrary to the stock muffler system, which uses the baffled, resonated chamber design, this exclusive design not only gives the Supersprint exhaust the right sound but also ensures an effective reduction in backpressure.
The Supersprint silencer's tapered cross-section, its overall volume, the inner, perforated core pipe diameter, all work together to best suit this Mercedes engine, ensure optimum results and give the ultimate, authentic V8 sound.
Supersprint used its exclusive design, oval & tapered cross-section silencer design, which has been developed specifically for all of the Mercedes models, which are equipped with a R & L exhaust, like the E W211, the CLS and the SLK R 171.
This particular, streamlined design uses the available space for the exhaust system at its best and keeps the silencer boxes tucked in and away from the direct air flow running under the car chassis. This feature ensures the least wind resistence.
The exclusive Supersprint muffler design also provides the right blend of exciting sound and optimum performance.
The Supersprint mufflers are available in the oval, 120x80mm quad-tip design.

Mid-pipe, with crossover, backpressure equalizing section

The Supersprint mid-pipe kit has been made with substantially larger than stock, Oversize tubes (2 x 70mm Vs. the smallish 2 x 60mm found on the oem exhaust).
This pipe kit has been developed with a special, X shaped crossover section, placed at the ideal distance from the engine, which equalizes the exhaust gas backpressure between the right and the left side cilynder banks of the Mercedes V8 motor.
This particular feature also exhances the armonic of the engine exhaust waves, and it guarantees a healthy, sport sound.

Headers

The key component of the Supersprint SL 55 AMG exhaust, instrumental to best performance, are the headers.
These very special headers have been designed and developed by Supersprint' own R&D team, as usual, and have been extensively tested on Supersprint own MAHA braked dynomometer .
While the stock headers use 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 merge collector patented design.
The Supersprint developement crew managed to squeeze these huge headers in the limited space available in the engine bay, and shaped them so well, that they can be easily fitted without the need for lifting the engine, or un-bolting the transmission or other parts.
