Step-by-step installation of the MagnaFlow 19432 loop delete pipe on 2018-2024 Jeep Wrangler JL and 2020-2023 Jeep Gladiator 3.6L. Get fitment tips and avoid common mistakes.
Quick answer
Install the MagnaFlow 19432 loop delete pipe on a 2018-2024 Jeep Wrangler JL or 2020-2023 Jeep Gladiator 3.6L to replace the factory loop section with a 2-inch mandrel-bent stainless pipe. Professional installation is highly recommended, so use this guide to plan the job or brief your shop.
Why the loop delete pipe changes the exhaust path
The factory exhaust on these 3.6L Jeeps includes a loop section that adds weight and can restrict flow. The MagnaFlow 19432 replaces that loop with a straight-through 2-inch mandrel-bent pipe, which is weight-optimized and designed for superior flow characteristics. The result is a simpler exhaust path that may support other performance upgrades, but it does not add a muffler or change the tone on its own—it is a pipe section, not a full cat-back.
Fitment boundaries and what to check first
The 19432 is listed for 2020-2023 Jeep Gladiator 3.6L and 2018-2024 Jeep Wrangler 3.6L. It is not a universal pipe. Before ordering, confirm your Jeep’s model year and engine, and inspect the factory exhaust for any previous modifications or damage. Because the catalog does not supply pipe diameter at the factory connection or specific hanger locations, you should verify those measurements on your vehicle or consult a professional—do not assume the pipe will bolt directly to a modified system.
Why professional installation is recommended
MagnaFlow explicitly recommends professional installation for this pipe. The job involves cutting or disconnecting the factory loop, aligning the new pipe, and securing it without leaks. Without a lift and exhaust-specific tools, rusted fasteners and tight clearance can turn a straightforward swap into a frustrating afternoon. If you plan to do it yourself, budget for penetrating oil, a reciprocating saw or cut-off tool, and a torque wrench.
Step-by-step installation
- 1. Verify fitment and gather tools: Check your Jeep’s model year and engine against the listed applications (2020-2023 Gladiator 3.6L, 2018-2024 Wrangler 3.6L). Gather safety glasses, gloves, penetrating oil, a reciprocating saw or cut-off tool, a socket set, and a torque wrench. Snap a photo of your factory exhaust before cutting—it helps with reassembly if you need to revert.
- 2. Lift and support the vehicle safely: Raise the Jeep on a lift or jack stands on level ground. Never work under a vehicle supported only by a jack. Let the exhaust cool completely before touching any component. Chock the wheels and use stands rated for your Jeep’s weight.
- 3. Disconnect or cut the factory loop section: Spray penetrating oil on the fasteners and let it soak. If the loop is clamped, loosen the clamps; if it is welded, measure and mark the cut point, then cut with a reciprocating saw or cut-off tool. Support the loop as you remove it to avoid strain on the remaining exhaust. Double-check your cut line against the new pipe’s length before cutting—measure twice, cut once.
- 4. Test-fit the MagnaFlow 19432: Slide the new pipe into position and check clearance to the frame, driveshaft, and nearby lines. The pipe should align without forcing. If it contacts anything, adjust the angle or check that you have the correct application. A pipe that needs to be forced into place will likely leak or rattle—stop and recheck fitment.
- 5. Secure the connections: Reuse the factory clamps if they are in good condition, or use new stainless clamps. Tighten the connections evenly, then torque to the manufacturer’s specification if available. If no specification is supplied, tighten to a snug fit and recheck after a short drive. Mark clamp positions with a paint pen so you can spot movement later.
- 6. Start the engine and check for leaks: With the vehicle still supported, start the engine and let it idle. Listen for exhaust leaks and watch for movement at the connections. A leak often sounds like a ticking or hissing near the joints. If you hear a leak, re-tighten the clamps and recheck alignment before lowering the Jeep.
- 7. Lower and road-test: Lower the vehicle, then take a short drive. After the exhaust cools, recheck clamp tightness and clearance. Re-torque if needed. Recheck after the first 50 miles—heat cycles can loosen clamps.
