Welcome to the Titsonic Designs cat-back exhaust system for the F8x platform, or in other words, the solution to the F8x sound problem. For years enthusiasts have wanted to find a solution to the buzzy and raspy sound these cars produce from the factory. Since these cars were released back in the late portions of 2014 we all knew there is world class sound lying under all the rasp. Our mission has been to find this hidden sound and allow all F8x owners to enjoy it. This full catback is comprised of a 2.75" equal length mid section with an H pipe configuration. After traveling through the H pipe the exhaust is combined into a 3.5-inch axle back. This combination helps smooth the exhaust tones to provide a very enjoyable sound through the entire rev range. When operating with the valves open, the exhaust gases exit unrestricted out of the passenger side exhaust tips. With the valves closed the exhaust passes through our quad chambered muffler and out of the drivers side exhaust tips for a lower volume experience, very well suited to daily driving and not alerting the Karens. This system mounts up to factory mounting points and is a direct bolt-on. No cutting or welding necessary. It's time to make the F8x sound like it always should have.

 

Sound Developments.

At Titsonic Designs, we are chasing perfection and we believe this, our equal-length exhaust setup, is the sound solution for F8x owners. Traditionally equal length exhaust configuration lowers the aggressive nature of the S55 engine. With this new design we have spent countless hours testing to ensure the raw aggressive sound is present through all rev ranges to give that emotion, but the equal length configuration allows for the sound to be very pleasurable rather than just loud. Owners coming from other non-equal length setups will not feel short-changed in regards to this setup's volume.

    *NOTE for all S55 OWNERS*
    Due to this system being unresonated, the “2k rasp” certainly can be present on a race, free flow downpipe setup when shifting at very low rpm’s. While OEM downpipes aren’t very restrictive below 700hp on factory turbos, in our experience 200 cell or similar high flow cat will provide the most refined sound experience while adding volume over stock downpipes if you’re looking for an additional upgrade in flow and or sound. 

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).
