The failure of the stock catalytic system happens very often on this type of cars, and it requires a costly replacement. The control of the exhaust temperature is extremely critical on all of the supercharged Mercedes engines. These features guarantee a dramatic reduction of the exhaust gas backpressure, and also allows for lower engine temperature in the head exhaust ports' area, when under a load, expecially at medium and high rpm. The Supersprint HJS cats, made in Germany by Emitec, the world leader in technology for performance, Metallic catalytic converters, are positioned further downstream in the exhaust system, and have the much lower cpsi rating of 100 cells per square inch. This design severly restricts the exhaust gas flow and the performance. ![]() ![]() 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 and over. The front section of the Supersprint exhaust uses 2 Metallic catalytic converters with 100cpsi rating, one cat each side. Metallic catalytic converters, with 100cpsi beds The Supersprint mufflers are available in the oval, 120x80mm quad-tip design. The exclusive Supersprint muffler design also provides the right blend of exciting sound and optimum performance. This feature ensures the least wind resistence. 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. ![]() 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. 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. 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.Ĭontrary 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. We guarantee precise fitment, unmatched performance gains, great sound and legendary durability.Īs the SL 55 AMG is quickly re-gaining value as a Classic Sport Roadster, the Supersprint Oversize diameter stainless exhaust is the perfect complement to it, and it is still available in its original form. With the Supersprint full exhaust in place, the light-in-the-back, powerful SL 55 AMG makes a perfect statement for "Muscle Car", "Supercharged", "Spinning Tires".Īs usual, it installs easily, without the engine being removed or lifted, needing no modifications. The Supersprint long primary tube headers and the HJS Motorport, high volume metallic cats system finally does justice to the SL 55 it turns the performance around, ensuring a gain of + 40 / + 50 Nm throughout the powerband, and + 30 Hp at peak.Īlso, it reduces heat soak, making the performance more consistent, and it provides for a substantial reduction in weight as well.Īt the same time, it makes the sound roaring deep when lugging the engine in the mid rpm, and screaming wildly, up on top. This engine needed more extensive work, in a different, specific area of the exhaust that is where all of the extra Hp was hiding.īlame it on the awfully small, necked down log manifolds, and on the heavily restrictive stock quad-catalytic.įor some reason (emission-related), the AMG factory R&D Team of engineers had given the SL 55 a nice, great flowing cat-back exhaust, but they must have had their hands tied behind their back, when designing the headers and catalytic. We proved it over and over again on the dyno, measuring exhaust gas backpressure and temperature alongside the power and torque curves. On the SL 55 AMG, working on the cat-back exhaust section had no effect it made not one extra hp over stock. In spite of the impressive acceleration and top speed, we knew that a lot of performance has been left on the table our R&R Team, here at Supersprint in Italy, made the plan to set it free, simple as it was. This is our original long tube headers project for the 2001-2006 SL 55 AMG Kompressor V8, the very first MB AMG model to be equipped with the legendary M113 Supercharged 5.5l engine.Īs opposed to the earlier M113 N/A engine version, the Supercharged M113 (Kompressor) made lots of extra hp at peak but most important, it made way more torque in the low and mid rpm range, as well. ![]()
