Supersprint is proud to introduce the new race exhaust for the 2011 Porsche 911 GT3 RS.

It is made by long tube headers, HJS Motorsport, large volume Race catalytics and a muffler with integrated, built-in Helmoltz-resonator chamber.
The extra-long primary tube design, the step-diameter, and the tuned, overall dimensioning, a trademark of Supersprint, make these headers the undisputed champion in performance, with substantial gains both in peak hp and in low and midrange rpm torque.
On the 911 GT3, a car made for the racetrack, most of the commonly known exhaust principles and ideas do not apply.
Our R&D crew has worked strenuously, with designing, building, testing and scrapping many prototype exhausts, until we finally came up with the perfect system.
The muffler design sports a built-in Helmoltz resonator chamber, which tames the db level down to meet the FIA regulations, yet it does not hamper nor reduces the exhaust flow rate by the slightest amount.
No need for funky hp-killer, nor other awful tail pipe add-ons.
Our system is built to be installed, ready to go, as is.
Performance-wise, the Supersprint long tube, step diameter primary headers and the HJS Motorsport, 100 cpsi large-volume cats are the perfect complement to the SS muffler; that is exactly what the high-revving engine of the GT3 needs.
Short headers designs only have a limited potential, regardless of their primary diameter; they add little or no power over the factory exhaust.
Instead, long tube headers are the ideal exhaust design.
Nowadays, this concept seems to have become the latest craze among the exhaust makers and the Porsche specialists, worldwide.
We can proudly say, Supersprint has invented and pioneered the concept, independently.
We learned our lesson and made it work, way before the others have embraced it.
On each of the GT3 versions, the Porsche Factory has gone through a steady, continuous development process on the engine, by increasing displacement, bumping up compression ratio, moving the redline higher, altering cam timing, redesigning the intake and fine tining the fuel & spark advance mapping.
Here at Supersprint in Italy, we too have done our homework non-stop, upgrading and improving our original design to larger diameter primaries, oversized exhaust ports, and adopting other subtle, yet significant features.
For instance, we went from 42mm primaries to step, larger diameter tubing, for more top-end power.
Porsche has continuously refined the original concept of the GT3 engine, getting to increase the baseline, stock performance, step-by-step; so did we at Supersprint, making the gains even more noticeable, with each of the upgrades to our long tube headers and race exhaust.
The weight of the full SS system is 26.5 kg, vs 39.2 kg of the stock exhaust.
