Product Details

Dynomax Super Turbo Universal mufflers are built around a combination-style muffler design that balances flow and sound control. The internal flow director helps guide exhaust gases through the case more efficiently, while the fiberglass packing reduces unwanted cabin resonance without creating an overly aggressive exhaust note. With a 20-inch body length, 25.5-inch overall length, 9.75-inch body width, and 4.25-inch body height, this muffler is sized for performance-oriented custom exhaust work where packaging and tone both matter. The aluminized finish adds corrosion resistance for everyday street use.

For shoppers comparing exhaust mufflers for Jeep Cherokee, Jeep Grand Cherokee, or Ford Ranger applications, the Dynomax 17747 offers a straightforward universal solution with confirmed fitment across multiple model years.

What This Muffler Helps Address

• Restricted exhaust flow from an aging or damaged muffler
• Excessive backpressure in a 2.25-inch exhaust system
• Harsh or resonant exhaust sound inside the cabin
• Need for a reversible universal muffler in a custom exhaust layout
• Replacement needs on Jeep Cherokee, Jeep Grand Cherokee, Ford Ranger, or Jeep Grand Wagoneer exhaust systems

Installation Notes and Tips

This is a universal muffler with pipe connection inlet and outlet sizing, so installation should be matched to the vehicle’s exhaust tubing and routing. Confirm available space for the oval body dimensions before welding or clamping into place. Because the muffler is reversible, it can be oriented to suit the exhaust path during fabrication or replacement work. Verify the 2.25-inch inlet and outlet dimensions against the existing system before installation.
