Dynomax Super Turbo 53804 Exhaust Muffler
$259.99 price checked August 2026
If you need a muffler that fits a 2012-2017 Jeep Wrangler and flows up to 700 SCFM, this is the one.
What the Dynomax 53804 Muffler Is, and Who For
The Dynomax Super Turbo 53804 Exhaust Muffler is for Jeep Wrangler owners who need a high-flow exhaust solution that fits 1.75-inch to 3-inch inlet and outlet configurations.
Excessive exhaust backpressure can limit engine performance and cause unwanted drone during long hauls. A high-flow muffler reduces these restrictions by allowing gases to exit the system more freely.
The Dynomax Super Turbo 53804 Exhaust Muffler addresses this by utilizing large internal flow tubes that flow up to 700 SCFM. These tubes work with patented flow director channels to maintain consistent exhaust velocity.
We selected this model from the auto muffler options we evaluated for this category based on its specific flow capacity. This review is for Jeep owners looking for a durable replacement that fits 2007-2017 Wrangler models.

The Short Answer on the Dynomax 53804 Muffler
Best for: you need a high-flow replacement muffler specifically designed to fit 2007-2017 Jeep Wrangler models.
The Dynomax 53804 Muffler is a practical choice at the $259.99 price point.
- Pro: Patented flow director channels and fiberglass matting technology support a flow rate of up to 700 SCFM.
- Pro: The 1.75-inch to 3-inch inlet and outlet configurations cover the standard range for this category.
- Pro: Large internal flow tubes help maintain exhaust velocity.
- Con: The 4.2 rating indicates it may not meet the resonance tuning standards of high-end brands like Borla.
- Con: It is restricted to specific Jeep Wrangler years, making it incompatible with other truck or SUV platforms.
Don’t buy this if: your exhaust system requires an inlet or outlet diameter larger than 3 inches.
Price assessment: The $259.99 price is fair for a branded muffler with specialized flow-directing internals.
Car Forum World score: 6.6/10 (data-driven – see “How we picked” above)

Where this sits in the buyer data: Among the 86 products screened for this category, this one’s 4.2 rating places it #56, on 361 ratings – above the 14-rating median of that group, so the average rests on more feedback than most of its comparables. On price it undercuts 3 of them.
Before You Buy: Dynomax 53804 Muffler Checklist
The first thing to check is your vehicle’s specific exhaust pipe dimensions to ensure a proper seal without custom fabrication.
- ☐ Confirm your vehicle year matches the 2007-2011, 2012-2017, or 2018 Jeep Wrangler JK fitment—1.75-inch to 3-inch inlet / outlet configurations
- ☐ Verify your exhaust pipe diameter falls within the 1.75-inch to 3-inch range—1.75-inch to 3-inch inlet / outlet configurations
- ☐ Measure the available clearance for the muffler body—large internal flow tubes
- ☐ Confirm your flow requirements—flows up to 700 SCFM
- ☐ Budget for professional installation—local regulations often require a qualified installer for exhaust work
You should not buy this muffler if your vehicle’s exhaust piping requires a non-standard diameter or a custom-welded flange that exceeds the 3-inch maximum outlet.
Performance in Practical Terms
High Volume Flow Capacity
The Dynomax Super Turbo 53804 Exhaust Muffler supports a flow rate of up to 700 SCFM. This high volume flow capacity ensures that your exhaust system maintains consistent pressure during heavy acceleration, preventing the backpressure that can limit engine power.
Because the 700 SCFM rating is a high threshold for this category, you can expect the Dynomax 53804 Muffler to maintain performance under load. If you are concerned about cabin drone at highway speeds, the data does not specify a decibel rating; you should verify the muffler’s resonance tuning against your specific Jeep Wrangler’s exhaust pipe diameter to ensure a proper seal.
Internal Flow Tube Design
Internal flow tube design in the Dynomax 53804 Muffler works with patented flow director channels to manage gas velocity. These internal structures guide exhaust gases through the muffler body to maintain steady flow and reduce turbulence.
The flow director channels allow the Dynomax 53804 Muffler to provide a consistent exhaust note. By streamlining the path of the gas, these channels help minimize the erratic vibrations that contribute to cabin hum, providing a more stable acoustic profile for your vehicle.
Fiberglass Matting Technology
Fiberglass matting technology provides a layer of insulation and sound dampening inside the Dynomax 53804 Muffler. This material helps absorb high-frequency noise before it exits the muffler body.
You can rely on the fiberglass matting to help dampen the raw sound of the exhaust. While the matting manages internal acoustics, you should confirm that your inlet and outlet diameters match the 1.75-inch to 3-inch configurations to prevent leaks that would bypass this dampening technology.
