The Cees-Exhaust Valved Sport Exhaust (Muffler Delete Edition) is the ultimate sound upgrade for the Porsche 718 4.0L platform.  By removing the bulky factory mufflers and replacing them with a high-flow, valved straight-pipe architecture, this system transforms your car into a true track weapon with an uncompromising exotic scream

Performance & Engineering

  • Material: T304 Stainless steel: 26.0 lbs lighter than stock

                              Grade 5 Titanium: 55.8 lbs lighter than stock

  • Precision TIG Welding: Expertly welded to endure sustained high exhaust temperatures and increased boost levels.
  • Refined Acoustics: Designed to deliver a deeper, more aggressive tone without the intrusive "drone"
  • 100% reversible—return to stock at any time.

🛠️ Key Product Features

  • Non-Muffled Design: A "muffler delete" configuration that provides the most direct path for exhaust gases, ensuring maximum sound volume.
  • High-Response Vacuum Valves: Features dual valves to bypass or engage the straight-pipe flow, giving you control over the volume.
  • OEM Bolt-On Fitment: Designed to utilize factory mounting points and exhaust hangers for a straightforward installation.

🏁 Performance & Sound Benefits

  • Unfiltered 4.0L Soundtrack: Delivers an incredibly raw, high-pitched, and aggressive race-car howl that is significantly louder than muffled systems.
  • Maximum Weight Savings: By eliminating the heavy internal baffling and packing of a traditional muffler, this stainless steel system drastically sheds rear-end weight.
  • Improved Exhaust Scavenging: The straight-through design minimizes backpressure, allowing the engine to breathe freely and gain peak horsepower.
  • Dual Character:
    • Valves Open: Pure, unadulterated race-car volume.
    • Valves Closed: Redirects flow to reduce decibel levels for a slightly more manageable street presence.
