aFe ROCKBASHER Cat-Back Exhaust — Jeep Gladiator 3.6L

ROCKBASHER cat-back with a muffler and turn-down exit for Gladiator 3.6L

The aFe 49-48082 ROCKBASHER cat-back uses 3-inch mandrel-bent 409 stainless tubing, one high-flow 409 stainless muffler and a turn-down exit. Its current manufacturer applications establish 2020–2026 Jeep Gladiator JT gas V6 3.6L. This is a muffler-equipped system; the selected guide contains conflicting muffler part numbers that require confirmation with aFe before disassembly or ordering a replacement muffler.

Key Features

• Selected aFe part 49-48082.
• 3-inch mandrel-bent 409 stainless tubing with hand MIG-welded construction.
• One high-flow 409 stainless muffler and a compact turn-down outlet.
• Front pipe, muffler and tailpipe use two supplied 3-inch band clamps.
• Direct bolt-on installation is described by the manufacturer without cutting or drilling.
• Transfer the original ball clamp and reuse factory hanger mounts and rear hanger-bracket bolts.
• The formal bill lists muffler 49M00017, but installation step 9 names 49M00030; confirm the actual supplied revision with aFe before beginning work.

FAQ

It is a 3-inch 409 stainless muffler-equipped ROCKBASHER cat-back with a turn-down exit for documented Gladiator JT gas V6 3.6L applications.

No. The exact current manufacturer explicitly specifies one high-flow 409 stainless muffler, and the selected guide includes a muffler in its bill and installation sequence.

The selected formal bill lists 49M00017, while step 9 names 49M00030. This source conflict is unresolved. Confirm the actual packing list and supplied/service revision with aFe before disassembling the vehicle or ordering an individual replacement muffler.

The current exact manufacturer applications establish gas V6 3.6L only. This listing does not establish EcoDiesel approval.

The manufacturer describes direct bolt-on installation without cutting or drilling. The guide releases the original front clamp and slides the supported factory exhaust back for removal in one piece.

No. The selected guide removes the spare tire and tire guard for access, then reinstalls both after alignment and tightening.

Transfer the factory ball clamp to the new front pipe. Remove the rear hanger bracket by its two bolts while fitting the new tailpipe, then reinstall the bracket with those original bolts. Retain the factory hanger mounts.

The selected guide specifies 40–45 ft-lb for band clamps, front-to-rear tightening after alignment, a leak check and re-tightening all clamps and hardware after 50–100 miles. It does not print separate ball-clamp or hanger-bolt torque or a fixed clearance dimension.

Installation Instructions

1. Confirm aFe 49-48082 against the exact vehicle and installed equipment. Inventory the actual components and follow the selected manufacturer instructions and current vehicle service requirements.
2. Read the complete selected two-page guide, verify the gas 3.6L JT application and inspect the actual components. Resolve the formal-bill muffler 49M00017 versus step-9 muffler 49M00030 discrepancy with aFe before disassembly. Professional installation is recommended.
3. Let the exhaust cool, wear protective equipment and support the vehicle and factory exhaust separately. Lay out the selected components and leave clamps loose during assembly. Remove the spare tire and tire guard for access.
4. Release the original front clamp and slide the supported factory exhaust back for removal in one piece. Transfer the factory ball clamp to the new front pipe and connect the front pipe to the factory Y-pipe.
5. Install the confirmed supplied muffler on the front pipe with the selected 3-inch band and support the muffler separately. Do not treat either conflicting printed muffler part number as an independently confirmed service replacement.
6. Remove the factory rear hanger mount by its two frame bolts. Install the tailpipe with the other 3-inch band and reinstall the factory hanger bracket with those original bolts.
7. Align all sections with safe clearance from wires, hoses, brake lines, body parts and tires. Tighten front to rear; band clamps use 40–45 ft-lb. No separate factory ball-clamp or hanger-bolt torque or fixed numerical clearance is printed.
8. Reinstall the tire guard and spare tire. Start the vehicle and check for leaks, correcting any cause before removing supports. Re-tighten all clamps and hardware after 50–100 miles.
