The aFe 49-48096-B Rebel cat-back uses 3-inch-to-2.5-inch mandrel-bent 409 stainless tubing, a resonator and a high-flow 409 stainless muffler, ending in two black 4.5-inch tips with riveted logo plates. The exact current manufacturer and selected guide explicitly exclude 4xe models. Resolve the guide’s clamp-size discrepancy and the manufacturer’s conflicting tip-alloy labels before relying on those details for installation or replacement parts.
Current exact manufacturer applications list Wrangler JL 2.0L turbo mild-hybrid 2018–2020 and 2.0L turbo gas 2020–2026. The selected September 2026 guide names both two- and four-door models and expressly excludes 4xe. The complete exact FR Sport table contains six original positive named scopes plus missing names through 2022; its three 4xe entries and Unlimited Rubicon 392 entry are overridden by the manufacturer’s 4xe exclusion and 2.0L-only scope and are not adopted. Later named-trim years remain unverified rather than extended from the 2026 model-level headline. This hybrid coverage concerns the stated mild-hybrid powertrain, not 4xe plug-in hybrid compatibility.

| Detail | Value |
|---|---|
| Manufacturer Part Number | 49-48096-B |
| Product type | Catback |
| Construction | Cat-back; 3-inch-to-2.5-inch 409 stainless tubing, high-flow 409 stainless muffler and MIG-welded construction. |
| Principal assemblies | Resonator 05-144608, extension 05-144609, over-axle assembly 05-244117 and selected black muffler 05-144397B. The uncoated muffler is a separate alternative. |
| Selected tips | One black 49T30451-B091 and one black 49T30452-B091, each 3-inch inlet x 4.5-inch outlet x 9-inch length. Main product copy calls both 304 stainless, but its related right-tip listing says 409. The alloy discrepancy remains unresolved; confirm with aFe if alloy or replacement-part specification matters. |
| Formal band-clamp bill | Two 3-inch bands 05-41055 and one 2.5-inch band 05-41061. Tip attachment bands visible in images are not used to invent extra formal bill quantities. |
| Clamp-size source conflict | The diagram places 3-inch bands at the front extension joints and a 2.5-inch band ahead of the rear muffler. Steps 10 and 11 instead both call for 2.5-inch bands. Confirm correct joint sizes, quantities and the actual packing list with aFe before disassembly; do not substitute blindly. |
| Selected guide | Two pages, all 18 steps, formal bill, diagram and installed photo; updated September 2026. Both pages explicitly exclude 4xe. |
| Tightening / follow-up | Printed band-clamp specification is 40–45 ft-lb, not a separately established factory ball-clamp setting. Align and tighten front to rear, inspect for leaks, and re-tighten all clamps and hardware after 50–100 miles. No fixed clearance dimension is printed. |
| Performance / emissions | Manufacturer describes a throaty sound; no selected measured power, decibel or drone result is established. No CARB EO number is required according to the manufacturer; this does not approve unrelated converter changes or the complete modified vehicle. |
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
It is the selected 3-inch-to-2.5-inch 409 stainless Rebel cat-back with a resonator, black muffler and dual black 4.5-inch tips for documented Wrangler JL 2.0T applications, excluding 4xe.
Does mild-hybrid coverage mean it fits a 4xe?No. The exact current manufacturer lists 2018–2020 2.0L mild-hybrid applications but expressly excludes 4xe plug-in hybrid models. Secondary 4xe-positive rows are not adopted. This selection does not establish V6 or V8 coverage either.
What changes between two- and four-door installation?The selected guide says to use the supplied extension first for four-door applications. Follow its exact diagram and confirm the clamp-size discrepancy before disassembly; do not invent a two-door cutting operation.
Why must the clamp sizes be confirmed?The formal bill lists two 3-inch bands and one 2.5-inch band, with 3-inch front joints shown in the diagram. Steps 10 and 11 both say 2.5 inches. Those instructions do not agree; ask aFe to confirm the joint sizes and actual packing list before installing.
Are the tip alloys fully consistent across the manufacturer listings?No. The main system copy calls the tips 304 stainless, while its related right-tip listing says 409. The tips are described here as black stainless with an unresolved alloy discrepancy; obtain confirmation if the alloy or replacement-part specification matters.
Which original parts must be retained?Keep the factory ball clamp from the original mid-pipe/resonator and the original rubber isolation mounts. If hanger brackets are unbolted to remove the rear muffler, refit the driver and passenger brackets and isolators before installing the front pipe, as the guide directs.
Does 40–45 ft-lb apply to the factory ball clamp?The printed range is for band clamps. No separate numerical factory ball-clamp setting is established. Resolve the joint-size discrepancy, align first, tighten front to rear, check for leaks and re-tighten all clamps and hardware after 50–100 miles.
Is a power gain or drone-free sound guaranteed?No selected dyno, decibel or drone result is established. The manufacturer’s throaty-sound description is qualitative and depends on the vehicle and the complete exhaust.
