Porsche 997 GT3 (3.6, 3.6 RS, 3.8, 3.8 RS)
The system available for the GT3 in all guises comes as a full system (headers, connecting pipes – catted or decatted - and rear muffler) or bypass kit + rear muffler.
Most systems in the market offer little in terms of power gains. The engineers at Supersprint are some of the most technically advanced in the industry and through extensive testing and experience have produced a system that releases 19.8hp with the catted version.
There are 2 options for headers. Standard and Inconel.
All Supersprint® are covered by a 36 month, unlimited mileage warranty.
The Bypass Kit
The existing tripe muffler design of the GT3 also has a pair of flapper valves, which by-pass the side mufflers, and re-route the exhaust gas directly from the cats to the main muffler, deleting the silencing effect of the side muffler completely. This happens at 4000 rpm, regardless of the engine load.
Under 4000 rpm there is no droning thanks to the effect of the side mufflers; above 4000 rpm the sound transforms to what we all recognize as the GT3 while the inside-cabin droning is rather tame and definitely tolerable.
Although the DB output is extremely high, the wave frequency at high rpm is less disturbing to the drivers' and passengers' ears.
Many owners do one simple mod initially; to remove the side mufflers (and their flapper valves), retaining the main, mid muffler only. This can be done via a rather inexpensive kit we supply in our GT3 program (part # 244613 + # 244643).
With this modification, the stock headers & CATs remain in place working in direct conjunction with the stock main center muffler only.
The sound above 4000 is the same as with the stock exhaust configuration, while under 4000, it grows and becomes so bad that the inside-cabin droning can become unbearable.
On some race circuits where the sound is measured under full acceleration (not the usual, stationary test at 3800 rpm), all of the 997 GT3s, stock or modified, are rejected just like the stock Ferrari 458 is - because they are too loud.
The Supersprint® main muffler solves this problem once for all as it has been designed with a built-in Helmoltz resonator which makes it quieter than the stock main muffler by a substantial amount.
This inner design of the main muffler makes the Supersprint® full headers system compliant with the sound regulations (when the drive-by sound test is done), at all of these selective racetracks.
It can be used with either the full SS system, or with the stock manifolds & CATs. It is FIA compliant, under both of the configurations.
Our full exhaust is the perfect choice for the track-oriented GT3 owner, in terms of performance, and also with regards to sound while the rear muffler alone, when used with the stock headers, does not add any HP but makes the car legal at the race track.
