Kooks RAM 09-18 1500 / 19-22 1500 Classic 5.7L HEMI Muffler Delete Pipe

Straight-Through 3-Inch T304 Stainless Steel Sound and Flow Upgrade That Bolts Directly to the Factory Dual Exhaust

The factory muffler on the Ram 1500 5.7L HEMI is the single largest restriction in the OEM exhaust path. The Kooks 35104000 eliminates it with a purpose-built 3-inch T304 stainless steel straight-through pipe that replaces the center muffler on factory dual-exhaust Ram 1500 trucks from 2009 through 2018 and 2019 through 2022 Ram 1500 Classic models. Because the 35104000 connects at OEM connection points and retains the factory tailpipes and tips, no cutting, welding, or custom fabrication is required. The result is a deeper, more aggressive HEMI sound at idle and under acceleration, reduced backpressure through the exhaust system, and a straightforward bolt-in installation that most experienced enthusiasts can complete in under an hour.

Mandrel-bent T304 stainless steel tubing maintains a consistent 3-inch inner diameter through every section of the 35104000, eliminating the flow turbulence caused by crush-bent pipes. The single-in, dual-out configuration matches the factory exhaust architecture of the Ram 1500 HEMI, which runs from the Y-pipe outlet into the center muffler and then splits to dual tailpipes on either side of the rear bumper. All necessary installation clamps are included. The 35104000 fits both two-wheel-drive and four-wheel-drive Ram 1500 HEMI trucks across the covered model years, and it accommodates regular cab, Quad Cab, and crew cab body configurations on both the 2009 through 2018 DS-generation platform and the 2019 through 2022 Ram 1500 Classic DS-platform continuation.

Key Features

• 3-Inch Straight-Through Muffler Delete: Removes the factory center muffler and replaces it with a straight-through T304 stainless pipe for unrestricted exhaust flow and aggressive HEMI tone.
• T304 Aircraft-Quality Stainless Steel: Premium stainless construction resists corrosion and withstands the sustained heat of the 5.7L HEMI exhaust for long service life.
• Mandrel-Bent Tubing: Constant 3-inch inner diameter through every bend ensures maximum exhaust flow with no restriction from pipe deformation.
• Single-In, Dual-Out Configuration: Matches the factory Ram 1500 dual exhaust architecture for a direct drop-in fit without any exhaust routing changes.
• OEM Connection Points: Connects at factory attachment locations so no cutting or welding is required for installation.
• Retains Factory Tailpipes and Tips: The existing OEM tailpipes and exhaust tips remain in place, preserving the factory appearance while transforming the sound.
• Clamps Included: All clamps necessary for a complete installation are supplied with the 35104000.
• Fits 2WD and 4WD: Compatible with both rear-wheel-drive and four-wheel-drive Ram 1500 HEMI applications across all applicable model years.

Installation Instructions

1. Allow the exhaust system to cool completely before starting. Never work on a hot exhaust system.
2. Raise the truck on a lift or secure on jack stands to provide comfortable working clearance under the rear of the chassis.
3. Locate the factory center muffler. Identify the three clamp connection points: one at the front inlet where the mid-pipe enters the muffler, and two at the rear outlets where the dual tailpipes exit the muffler.
4. Apply penetrating lubricant to all clamp hardware and allow it to soak for several minutes, particularly on older or rust-prone applications.
5. Loosen and remove the front inlet clamp using a 16mm socket. Loosen and remove the two rear outlet clamps using a 15mm socket.
6. Disconnect the muffler hanger rods from the rubber OEM isolators. There are typically two to four hanger mounting points on the center muffler assembly. A hanger removal tool or pry bar will ease removal.
7. With all clamps loose and hangers disengaged, slide the factory muffler free from the inlet pipe and the dual tailpipes. Set aside for disposal.
8. Compare the Kooks 35104000 muffler delete pipe to the removed factory muffler, verifying inlet diameter, outlet positions, and hanger rod locations match before installation.
9. Slide the provided clamps onto the inlet and outlet connection points of the 35104000 before raising it into position. Engage the hanger rods in the factory rubber isolators.
10. Connect the 35104000 inlet to the mid-pipe and both rear outlets to the factory tailpipes. Hand-tighten all clamps to hold position, then verify alignment and clearance before fully torquing all clamp hardware to specification.
11. Start the engine and inspect all connection points for exhaust leaks. Re-torque any leaking connections after the system reaches operating temperature.

Frequently Asked Questions

Q: Does the Kooks 35104000 fit both 2WD and 4WD Ram 1500 trucks?
A: Yes. The 35104000 is compatible with both two-wheel-drive and four-wheel-drive Ram 1500 and Ram 1500 Classic applications equipped with the 5.7L HEMI engine and factory dual exhaust. The driveline configuration does not affect muffler delete fitment.

Q: What is the difference between the 2009 through 2018 Ram 1500 and the 2019 through 2022 Ram 1500 Classic?
A: The 2019 model year saw Ram introduce an all-new fifth-generation DT-platform Ram 1500. Rather than discontinuing the previous DS-generation body style, Ram kept it in production as the Ram 1500 Classic through 2022 as a value-priced option. The 35104000 covers both the 2009 through 2018 DS-generation Ram 1500 and the 2019 through 2022 DS-based Ram 1500 Classic. It does not fit the 2019 and newer Ram 1500 DT platform.

Q: Does this muffler delete require cutting the exhaust?
A: No. The Kooks 35104000 is designed to connect at factory OEM attachment points using the included clamps. No cutting or welding is required for a standard installation on trucks with an unmolested factory exhaust system.

Q: Will the Kooks 35104000 work with my Ram 1500 if it only has single exhaust from the factory?
A: No. The 35104000 is designed specifically for Ram 1500 trucks equipped with the factory dual exhaust system. Single-exhaust applications have a different mid-pipe and muffler configuration that is not compatible with this product.

Q: Do 2009 and 2010 model year trucks work with this muffler delete?
A: Yes. The 35104000 fits 2009 and 2010 Dodge-branded Ram 1500 trucks equipped with the 5.7L HEMI and factory dual exhaust alongside the 2011 through 2018 Ram-branded 1500 trucks. The muffler delete fits the DS-platform exhaust architecture used across the entire 2009 through 2018 production run.

Q: Does removing the muffler cause a check engine light or require a tune?
A: The factory muffler on the Ram 1500 does not contain oxygen sensors or any electronic components. Removing it and replacing it with the 35104000 straight-through pipe will not trigger a check engine light or require an ECU tune.

Q: What is the warranty on the Kooks 35104000?
A: Kooks provides a limited lifetime warranty on all stainless steel components to the original purchaser. Coverage is governed by the Magnuson-Moss Warranty Act, meaning installation of this aftermarket exhaust component does not void your vehicle's factory powertrain warranty solely on the basis of the modification.

Q: Is the Kooks 35104000 louder than a cat-back exhaust system?
A: The 35104000 replaces only the center muffler and retains the factory tailpipes. The resulting sound is significantly more aggressive than stock but different from a full cat-back replacement, which also changes the downstream pipe diameter and tips. For maximum sound impact with retained factory tips, the 35104000 is one of the most effective single-component changes available for the 5.7L HEMI platform.
