Shark Werks Exhaust System for 992 GT3
Developed by lifetime car and motorsport enthusiasts with a passion to build the best sounding exhaust possible.
When Porsche's 992 GT3 models hit the market, the verdict was that this car simply dominated the previous generations with performance, aerodynamic functionality, and new technology.
The wailing howls of the previous generations seemed subdued, and in their place was a muddy sound and an electronic valve system that seemed to have a mind of its own. While the car would open the valves to start with a loud bark, it would then quickly quiet down, and even on the louder modes, the exhaust would sometimes close the valves and refuse to make the noise that was characterstic of the race bred GT3.
With this in mind, we focused our efforts on developing prototypes in order to extract some of the lost noises we were so fond of in the previous generations.
This design came about from numerous tests and challenges. We developed precision CNC-machined rings that perfectly fit the enormous 8" catalytic converter (or OPF in International markets) outlets, then meticulously welded these to high flow cones within the size constraints of the original exhaust. We chose dual mandrel bent 3" tubing with a large crossover tube, and additional extension tubes were added to tune the sound to what we believed was the best tone possible with no unpleasant drone or resonance on the inside. Our goal was for it to be fun on the outside, and yet classy on the inside; without giving you a headache. We made sure the exhaust still exits in the original location of the bumper, through integrated slashcut dual 100mm tips like our 991 GT3 upgrades.
The result from these changes is an aggressive startup bark, and an exciting tone under acceleration, but on a car that can still be driven on long trips while conversing with a passenger or talking on the phone when needed.
At idle, gentle throttle, or between 50 and 80 MPH in top-gear, the car is surprisingly docile, but downshifting and getting into the power still rewards you with a song worthy of the GT3 name.
The electronic valves are removed using Soul Performance Valve Delete Modules to prevent check engine lights or error codes, which we believed are the best available on the market.
The default finish is a flawless stainless steel, but you can request to have the exhaust tips and center component ceramic coated if you prefer a satin black finish (please note: this adds approximately 2-weeks to the build time).
- Louder, exotic and aggressive tone without uncomfortable drone or resonance at highway speeds
- 100% Made in the USA, stainless steel construction
- Removes about 20 pounds from the rear of the car
- Optimized for maximum power output and weight savings while retaining reliability, without modifying ECU programming
- Does not affect emissions systems, catalytic converters, or cause Check Engine lights (50-state Emissions Legal)
- 100% reversible, OEM-like fitment, with no cutting or welding required
** NOTE: The original Porsche exhaust clamps that attach the muffler to the car to the catalytic converter can be added for an additional charge, or you can remove them from your original muffler by removing a small metal tab. It can still be re-used on the original or Shark Werks Exhaust later.
** NOTE 2: At this time this exhaust is only available for USA models without particulate filter equipped
