The 981 Cayman and Boxster is a dream platform. Perfectly balanced, but lacking sound from the factory. That is where we come in! Welcome to our catback for the 981 platform. Measuring 2.5 inches from the headers back, this system takes the already decent sound 981 Porsches into the stratosphere. When operating in the valves open mode, exhaust gasses flow uninterrupted through to our X-pipe and out our beautiful 3.5-inch exhaust tips. Step up your sound game with us at Valvetronic Designs, you won't be disappointed.

Product features

Materials and care

Valved sport exhaust systems are crafted from premium materials to ensure durability, performance, and an aggressive exhaust note.  Common materials include:

Stainless Steel (304/409 Grade)

  1. Pros: Corrosion-resistant, durable, cost-effective.
  2. Best for: Daily-driven cars, budget-friendly systems.
  3. Care: Rinse with water after winter/salt exposure;  occasional polish with metal cleaner.

Titanium (Grade 1/2 or Ti-6Al-4V Alloy)

  1. Pros: Ultra-lightweight (50% lighter than steel), high heat resistance, exotic blue/purple heat discoloration.
  2. Best for: Track-focused builds, supercars (e.g., McLaren, Lamborghini).
  3. Care: Avoid abrasive cleaners;  use mild soap + microfiber cloth.

Inconel (High-Temperature Alloy)

  1. Pros: Extreme heat resistance (F1/racing use), no warping under stress.
  2. Best for: Turbocharged hypercars (e.g., Porsche 911 GT2 RS).
  3. Care: Minimal maintenance;  inspect for cracks under heavy track use.

Carbon Fiber Tips/Accents

  1. Pros: Lightweight, aesthetic appeal.
  2. Care: Wipe with damp cloth;  avoid harsh chemicals to prevent resin damage.

Valve Mechanism Components

Actuators: Electric or vacuum-controlled (OEM-style reliability).

Butterfly Valves: Stainless steel or titanium flippers for smooth operation.

Control Modules: Bluetooth/Wi-Fi (Armytrix), OEM integration (Akrapovic).

Care & Maintenance Tips

To preserve performance and appearance:

✅Do’s

Rinse after winter/salt exposure (stainless steel systems).

Use high-temperature exhaust polish (for shine + corrosion protection).

Lubricate valve hinges annually (silicone spray to prevent sticking).

Check for leaks/loose clamps (after installation or track days).

❌Don’ts

Avoid acidic wheel cleaners (can stain titanium/exotic metals).

Don’t force valves manually (may damage actuators).

No pressure washing near valves/electronics (risk of water ingress).
