MERCEDES R230 SL 500 V8 (M113 - 5.0L - 3v) '01 ->'05

Rear mufflers

The Supersprint Right & Left rear mufflers use the Free-Flow design, typical of all of the Supersprint performance systems. These mufflers come with a made in Germany, EEC homologation, which makes them road legal, worldwide.
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, when mated to the full Supersprint system.
The Supersprint silencer canister tapered cross-section, its overall volume, the inner, perforated core pipe diameter, all work together to best suit this Mercedes V8 n/a, 3-valve engine, and ensure optimum results. Supersprint uses this exclusive, oval & tapered cross-section silencer design, which has been developed specifically for all of the Mercedes models with a R & L exhaust placed directly behind the rear wheels , like the SLK 171, the E W211, and the CLS.
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 resistance. The exclusive Supersprint muffler design also provides the right blend of exciting sound and optimum performance, while never becoming obnoxious, at any rpm.
The Supersprint SL 500 mufflers are available in the quad, 120x80mm elliptical tip design, or in the dual, 145x95mm elliptical tip version.
And since the Supersprint tips are separate from the canisters, the bolt-on system with its ring clamp allows for a full range of adjustability upon the installation, and guarantees fine tuning the tips position to the rear bumper skirt.

Resonated mid section / Mid pipes

Placed between the Supersprint X-pipe and the rear mufflers, a set of 63.5mm mid pipes further enhance the sound and the flow over the stock components.
A set of right & left, mid resonators is also available, for a more subdued exhaust note, especially at low rpm.

Headers

The key component of the Supersprint SL 500 exhaust, instrumental to best performance, are 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 .10 bar, the ideal figure for the best performance.
This 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 just 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.
The Supersprint development 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 modifying or un-bolting the transmission or other parts for added clearance.
This headers only fits the left hand drive SL model.
