Developed by lifetime car and motorsport enthusiasts with a passion to create the best sound 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.
However, many people familiar with GT cars, especially those modified with parts like our popular Sports Exhaust on 991 and 997 GT3 models, found that the exhaust was a bit muted, and the electronic valve did not make as much of a difference to switch on or off as it did on previous models, making it even less useful.
The wailing howls of the previous generations seemed subdued, and in their place was a muddier sound, maybe not the familiar 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
- No bumper removal required for installation
** 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 not available for European Union and GPF sensor cars (coming soon/specify)
