Dynomax 17236 Exhaust Muffler

Dynomax Ultra Flo Welded Muffler Overview

The Dynomax Ultra Flo Welded Universal exhaust muffler is a stainless steel performance muffler built for straight-through flow and a deep performance tone. Part number 17236 is a universal fit option for custom exhaust work and select vehicle applications, including Jeep Grand Cherokee and Jeep Commander setups.

The Ultra Flo Welded product line focuses on welded stainless construction, high-flow exhaust routing, and resonance control through Continuous Roving Fiberglass (CRF) technology.

Product Description

Dynomax 17236 is a performance stainless steel muffler with a straight-through internal path that supports high exhaust flow while helping control unwanted cabin resonance. Its absorption-style construction uses CRF technology to manage sound without closing off exhaust flow, making it suitable for performance builds that need a deeper tone and less restriction.

Because this is a universal muffler, final installation depends on the vehicle’s exhaust layout, pipe diameter, and available space. The 2.5-inch inlet and outlet, 29-inch overall length, and oval body dimensions should be verified against the existing system before fabrication or replacement work. This part is commonly searched for as a Jeep Grand Cherokee muffler replacement and as a Jeep Commander performance muffler, and it also appears in Dodge Dakota and Mitsubishi Raider single-exhaust applications.

This part cross-references Walker 21436 and MagnaFlow 12256 for the same application.

What It Helps Address

• Exhaust restriction from a worn or restrictive muffler
• Excessive interior resonance from a less refined exhaust setup
• Loss of exhaust flow in performance-oriented builds
• Need for a stainless steel replacement muffler
• Custom exhaust packaging where a reversible universal muffler is required

Installation Notes and Quality

Confirm inlet and outlet diameter, body length, and available underbody clearance before installation. Because the Dynomax Ultra Flo Welded Universal muffler is reversible, it can be oriented to suit the exhaust routing, but final fitment should be matched to the vehicle’s pipe configuration and fabrication plan.

Dynomax backs the Ultra Flo Welded muffler line with a Limited Lifetime Warranty and a 90-Day Performance & Sound Guarantee. The welded stainless construction and performance-focused design are intended for long-term use in street and custom exhaust applications.
