Add Power and great sound and experience your Porsche’s true capabilities with the Dundon Power Package. Intentionally designed to bring big power with and distinct sound we all love, this kit is perfectly tailored to add more muscle, better sound, and increased performance to your specific GT car.
The Dundon D4 Package is the culmination of our work on perfecting and guiding the pressure waves into and out of the 3.4L Engine resulting in 40lbft max gains over stock and 62whp at 7000rpm. The Street Power Package is for street driven Boxsters and Caymans and includes 200 CPSI Cats and retains exhaust valves. You can choose to purchase a 997/991 GT3 muffler on your own, or purchase a lifetime muffler in Loud or Quiet with PVD Black Tips or Optional Titanium Tips.

62 max wheel hp gains at 7000rpm 40 max wheel lb-ft gains at 3800rpm 46 peak wheel hp gains 17 peak wheel torque gains This kit is fully bolt on, and completely reversible. Works for 981 Cayman S, GTS and Boxster S and GTS. The Kit consists of:
- Dundon Race Headers - Proven 4th tube technology aids in suction wave strength giving our headers the most power
- 321 Stainless, fully purged TIG welded construction and a lifetime warranty
- Dundon Valved GT3 Muffler Adapter (w/ 200 CPSI Cats) - Replaces the stock muffler with 2.5" 321 Stainless Steel over axle pipes
- Valved GT3 Muffler Connectors (your exhaust button still works)
- Cobb Accessport with Dundon Pro Tune - The standard for handheld tuning devices, allows logging, flashing and converting back to stock with ease (you can even resell it later to another 981 owner)
- Dundon Intake Runners - Directing and timing the pressure waves coming into and leaving the engine is what we do. The Dundon Intake Runners show this and enable large gains, carrying power all the way to redline, where the stock intake runners fall flat
- Dundon Lifetime GT3 Muffler (optional Orange Quiet Muffler) - Our bullet proof 321 Stainless Steel muffler with correct-length 981 tips, comes in 2 flavors. Black (loud) a bit more aggressive than an OEM muffler but with the drone cancelling upper pathway, and a full 3" lower pathway with an X pipe for the tip outlet (further enhances scavenging). Orange (Quiet) for those cars that run on dB restricted tracks combining Cats and a Quiet Muffler is a great way to "fly under the radar" and keep the car's bravado reeled in!
