🔊 Piston Twistin Varitune Adjustable Muffler – Double Offset 2.75” Stainless Steel

Part #31025

Fine-tune your exhaust tone and performance with the Piston Twistin Varitune Adjustable Muffler — a fully adjustable performance muffler designed for enthusiasts who want total control over sound and flow. With a built-in internal Power Valve system, you can switch from a deep, refined rumble to an aggressive, race-inspired exhaust note in seconds — all with a simple turn of a wrench.

Crafted from high-grade stainless steel, this muffler features a low-restriction, chambered flow design engineered for maximum performance, durability, and sound control.


⚙️ Features:

  • 🎚️ Adjustable Sound Control – Tune your exhaust tone and flow instantly using the built-in Power Valve system.

  • 🔊 8–10 dB Sound Range Difference – Transition from stealthy and quiet to full performance roar.

  • 💨 Low-Restriction Chambered Design – Maximizes exhaust velocity for noticeable horsepower and torque gains.

  • 🔩 Double Offset Configuration – 2.75” offset inlet and outlet design for versatile installation.

  • 🧱 Premium Stainless Steel Construction – Built from 439 stainless steel casing with 304 stainless tubing.

  • 🧰 Universal Fitment – Ideal for custom exhaust builds or direct-fit for select vehicles.

  • ⚙️ 5/8"-11 Adjustment Nut – Simple, wrench-accessible tuning in seconds.


🧠 How It Works:

The Piston Twistin Varitune Power Valve allows full control of airflow through the muffler:

  • Closed Position: Routes exhaust through all three internal chambers for a deep, mellow tone ideal for cruising.

  • Open Position: Opens the valve for a straight-through path — increasing flow, power, and producing an aggressive, race-inspired exhaust note.

Essentially, you’re getting two mufflers in one — quiet and composed for the street, or free-flowing and loud for performance driving.


🚗 Vehicle Fitment:

  • 2.75” diameter is a direct-fit option for 2011–2014 Ford Mustang.

  • Universal design works for a wide range of applications (custom fabrication may be required).


📏 Dimensions:

  • Case Length: 12.5”

  • Case Width: 9.75”

  • Case Height: 4.25”

  • Overall Length: 17.75”


🧱 Built to Last:

Each Piston Twistin Varitune muffler is precision-crafted using both robotic and hand welding techniques for superior strength and performance. The stainless steel shell resists corrosion and heat damage — ensuring long-lasting sound quality and reliability even under extreme driving conditions.
