aFe Ram 1500 Dual-Exhaust Muffler Delete 2009-2019

Factory-dual-exhaust muffler delete details

aFe 49C42072NM This 3-inch to 2.5-inch mandrel-bent 409 stainless assembly replaces the original muffler in a compatible factory dual-exhaust system. It retains the original tailpipes, tips and rubber mounts. The selected bill contains one delete assembly and three clamps.

Key Features

• 5.7L V8 and FACTORY DUAL EXHAUST ONLY; factory single exhaust excluded.
• 2009–2018 Dodge/RAM 1500 plus 2019 RAM 1500 Classic.
• 3-inch to 2.5-inch mandrel-bent 409 stainless tubing; 100% MIG welded.
• One delete assembly, one inlet clamp and two rear clamps.
• Original tailpipes, tips and rubber isolation mounts retained.
• No cutting step in the selected manual; manufacturer states no cutting required.
• Rear-clamp size/style discrepancy must be checked against actual supplied hardware.

Fitment

Dodge/RAM 1500 with the 5.7L V8 and FACTORY DUAL EXHAUST ONLY: manufacturer coverage is 2009–2018 plus the 2019 RAM 1500 CLASSIC. The exact primary explicitly excludes factory SINGLE exhaust. The 2019 Classic application does not establish fitment to the separate newer DT truck. Match both rear connections, original hangers and engine. Named applications remain subject to that dual-exhaust requirement; Special Service 2014–2016 is specifically supported as 4WD in the selected retailer list. Additional drivetrain applications are not inferred. The positively indexed 2014 HFE row is not added without confirmation of its actual 5.7L/dual-exhaust configuration.

Verify 49C42072NM against the actual engine, flange, hangers and mounting locations and applicable emissions requirements before ordering.

Specifications

What's Included

• 1 x 05-144783: Selected delete assembly.
• 1 x 05-41055: 3-inch inlet clamp.
• 2 x 05-41210: Rear clamps; bill 2.5 inches vs step 2.25-inch band wording conflict.

ONE selected muffler-delete assembly 05-144783, ONE 3-inch inlet clamp 05-41055 and TWO rear clamps 05-41210. The exact bill labels the rear clamps 2.5 inches; steps 9 and 10 instead say 2.25-inch band clamps. This size/style discrepancy is unresolved: compare actual supplied clamps and matching instructions before installation. Muffler assembly 05-144784 is the shared manual’s alternative and is NOT included in this delete selection. No separate driver/passenger tailpipe assemblies, tips, valve motors, sensors or new flange gaskets are listed. Retain the vehicle’s original tailpipes, tips and rubber mounts.

Disconnect the DRIVER-SIDE tailpipe behind the muffler, then the PASSENGER-SIDE tailpipe. Remove the original muffler at its FRONT clamp. The manual does not direct cutting for this selected kit.

No. The bill lists the selected delete assembly, one front clamp and two rear clamps. The muffled assembly is an alternative. Reconnect the original tailpipes and reuse their original rubber mounts; the steps’ aFe-tailpipe wording does not create extra supplied assemblies.

The bill identifies two 05-41210 clamps as 2.5 inches, while installation steps call them 2.25-inch bands. This is an unresolved source conflict. Verify the actual supplied hardware and its applicable torque instructions; do not infer size or style from a service number alone.

Reconnect driver then passenger tailpipes. If needed, loosen the original tips and center them in the bumper cutouts. Check complete-system clearance, then work from front toward rear. The manual gives 40–45 ft-lb for BAND clamps; verify the actual rear-clamp style before applying that value.

Re-tighten ALL clamps and hardware after 50–100 miles. Start the engine and repair any leaks before lowering the vehicle at installation. No battery, sensor or valve-coding procedure is specified.

Current manufacturer states no CARB EO number is required; this does not waive sound or usage requirements or authorize changing unrelated emissions equipment. No actual dyno or airflow chart is linked for this selection, and no measured drone result is supplied. Generic product-page filter/coupler fields do not add intake components to this exhaust bill. Rear-clamp size/style wording requires verification against the supplied parts.

Installation Instructions

Verify aFe 49C42072NM.

1. Read both pages of the selected September 2026 shared manual, all 16 steps, both assembly drawings and installed photos. Confirm the 5.7L engine and FACTORY DUAL EXHAUST; factory single exhaust is expressly excluded. Cool the exhaust, use eye and hand protection, and support the vehicle and exhaust independently at appropriate positions. Leave new joints loose for alignment.
2. Disconnect the DRIVER-SIDE original tailpipe at the REAR of the original muffler FIRST, then disconnect the PASSENGER-SIDE tailpipe. Remove the original muffler assembly at the clamp in FRONT of the muffler. The exact manual gives no cutting step, consistent with the manufacturer’s no-cut statement for this kit.
3. Install selected delete assembly 05-144783 with the ONE supplied 3-inch inlet clamp 05-41055. Slide its hangers into the original rubber isolation mounts. The shared diagram’s muffled assembly is an alternative, not another supplied section.
4. Reconnect the original DRIVER-SIDE tailpipe, then the PASSENGER-SIDE tailpipe, returning their hangers to the original rubber mounts. Use the TWO supplied rear clamps. The bill calls them 2.5 inches while steps 9–10 say 2.25-inch bands; resolve actual clamp size/style and instructions before tightening. The steps’ “aFe tailpipe” wording does not establish additional tailpipes in a bill that lists none.
5. If needed, loosen the ORIGINAL EXHAUST TIPS and center them in the bumper cutouts. Align the entire installation and check safe clearances from wires, hoses, brake lines, body and tires.
6. Starting at the FRONT, evenly tighten clamps and fasteners. The selected manual specifies 40–45 ft-lb for BAND CLAMPS. Because rear-clamp size/style wording is inconsistent, verify the correct specification for the actual supplied rear clamps rather than applying a band-clamp value to another clamp design. No separate fastener torque is provided.
7. Start the vehicle and repair any leaks before lowering it safely. Re-tighten ALL clamps and hardware after 50–100 miles. No battery-disconnection, sensor-transfer, valve-motor or coding procedure is specified.

Current manufacturer states no CARB EO number is required; this does not waive sound or usage requirements or authorize changing unrelated emissions equipment. No actual dyno or airflow chart is linked for this selection, and no measured drone result is supplied. Generic product-page filter/coupler fields do not add intake components to this exhaust bill. Rear-clamp size/style wording requires verification against the supplied parts.
