What a Resonator Delete Does
The stock exhaust on most RAM 1500/2500/3500 trucks includes a resonator to smooth out exhaust tone and reduce drone or harshness. A resonator delete removes that resonator, and with Khaos Motorsports’ 304-stainless delete pipe, you replace stock restriction with straight-through flow and raw exhaust tone. The result: deeper rumble, freer exhaust flow, and a more aggressive exhaust note, without having to go full muffler delete.
Resonator vs Muffler, What’s the Difference?
-
Resonator: Designed to target and cancel specific sound frequencies, smoothing out exhaust tone before muffler processing. Walker Exhaust+2mechaniquad.com+2
-
Muffler: Reduces overall noise level and dampens exhaust volume through baffling/chambers. Hendersonville Muffler & Brakes+1
Deleting the resonator keeps the stock muffler in place, preserving volume control, while changing exhaust tone and flow characteristics.
What the Khaos 304 Stainless Delete Offers
-
Material & construction: 304-grade stainless, resists corrosion, withstands high temps, and lasts longer than mild steel.
-
Flow path: Straight-through pipe, no chambers, reduces turbulence and backpressure compared to stock resonator.
-
Tone & sound: Expect a firmer, deeper, more throaty exhaust note under throttle, more pronounced turbo-back or cat-back flow, and a stronger V8 rumble.
-
Fitment: Direct-fit replacement for 2009-2019 RAM trucks with 5.7 L HEMI or 6.4 L HEMI, designed to match factory exhaust geometry for bolt-on simplicity.
With a stainless delete, you get durability plus aggressive exhaust behavior that complements other modifications (headers, cat-backs, etc.).
Stock Exhaust vs Resonator-Deleted Exhaust, What Changes
| Attribute | Stock with Resonator | With Khaos 304 Stainless Delete |
|---|---|---|
| Exhaust Tone | Smooth, mellow, restrained | Deeper rumble, aggressive, raw V8 tone |
| Exhaust Flow | Slight restriction from chambered resonator | Straight-through, less restriction |
| Muffler Output | Balanced volume & tone | Balanced volume (stock muffler still there), raw tone change |
| Drone at Cruise | Low, comfortable | Possible drone, depends on muffler & cabin acoustics B2 Fabrication+1 |
| Longevity / Durability | Stock materials; prone to corrosion in time | 304 stainless resists corrosion, heat, and lasts longer |
Who Benefits Most from a Resonator Delete
-
RAM owners with dual-intake, cat-back, or full-exhaust upgrades, helps free up flow for max gains.
-
Enthusiasts wanting deeper exhaust tone without going muffler-delete loud.
-
Drivers in dry / northern / rust-concerned environments, stainless resists rust far better than stock parts.
-
Anyone building a performance or daily-driver with attitude, stronger exhaust note and flow, but still manageable for street.
If you’re running stock exhaust and prefer quiet cruise, this mod may strike the wrong balance, it’s best for builds focused on tone, flow, or aftermarket exhaust.
Sound & Flow, Pros and Tradeoffs
Pros:
-
Sharper, deeper exhaust tone, especially under throttle or load DEA Performance+1
-
Slight flow improvements, helps when paired with other mods
-
Long-lasting stainless build, durability for years of use
Tradeoffs / What to Expect:
-
Possible cabin drone on long cruises, resonator deletion can amplify certain frequencies. B2 Fabrication+1
-
Changes in exhaust tone may not be “better” for everyone, sound preference is subjective.
-
Power gains are usually modest, a resonator delete alone seldom produces large HP gains unless part of a full flow-optimized system. MotorTrend+1

FAQ
Will a resonator delete make my RAM significantly louder?
You’ll get a deeper and more aggressive exhaust tone, but with the stock muffler still installed, the change is more about tone than raw volume.
Does it improve horsepower or torque?
Alone the gains are modest, but when combined with other exhaust or intake upgrades, the improved flow helps overall system performance.
Will I get cabin drone or harsh sound during cruising?
Possibly, resonator deletion may bring more mid-range frequencies into the cabin, especially on long highway drives.
Is it a simple install?
Yes. This is a direct-fit part for 2009–2019 RAM 5.7 L / 6.4 L HEMI trucks. Basic exhaust-system tools suffice.
Does it affect emissions or legality?
It removes a sound-control device, depending on your local laws, it may influence noise compliance. Always check local regulations before modifying exhaust.
