aFe 49-36354-C MACH Force-Xp uses 3-inch to 2-1/2-inch 304 stainless tubing and a 304 stainless muffler with dual carbon-fiber-finished outlets. The exact manual requires cutting and reusing the original converter/resonator front section, plus cross-brace spacers.
MINI Cooper S 2014-2024 and John Cooper Works 2015-2024 with 2.0L turbo engine, subject to exact body/chassis and original exhaust connections. Primary says 2-door only; its manufacturer release lists F56 and selected F57 convertible applications, while the September 2026 manual says 2-door and convertible but starts at 2015. Retain the positively supported 2014 S scope with this source qualification. Confirm an F57 convertible directly against its exact year/engine and boxed instructions before ordering; no F55 four-door, Clubman or Countryman fitment is inferred.

| Manufacturer Part Number | 49-36354-C |
| System | MACH Force-Xp cat-back; selected carbon-fiber tips |
| Tubing / muffler | 3-inch to 2-1/2-inch 304 stainless tubing; 304 stainless muffler |
| Selected tips | Two 49T25354-C07; 2-1/2-inch inlet x 3-1/2-inch outlet x 7-inch length; carbon-fiber/304 stainless |
| Adapters | S: 2.375-inch ID; JCW: 2.75-inch ID; actual factory connection determines selection |
| Brace hardware conflict | Procedure calls for six new M8 front-brace bolts not itemized in bill; length and supply unverified |
| Band-clamp torque | 40-45 ft-lb; no separate tip/bracket/brace-fastener numeric torque supplied |
| Recheck | 50-100 miles |
| Actual linked dyno | At marked 3,412 rpm, selected run is 148.94 versus 139.81 HP, plus 9.13 HP, and 229.29 versus 215.23 lb-ft, plus 14.06 lb-ft. Separate maxima are 220.48 versus 220.23 HP, plus 0.25 HP, and 231.25 versus 221.57 lb-ft, plus 9.68 lb-ft. Thus advertised 9 HP/14 lb-ft represents the marked point rather than peak-to-peak. Both runs identify 2024 MINI Cooper 2.0L turbo, fourth gear, 2,000-rpm start, red/yellow fans. Selected all-stock-with-aFe-cat-back January 21, 2025 at 3:58 PM SAE 0.98; all-stock baseline January 23 at 9:45:24 AM SAE 0.97. Dynojet 424xLC Linx, inductive RPM, Linx not connected, smoothing 5.

Does this require cutting?Yes. Cut 7 inches from the rear weld of the original resonator as shown by the exact manual. Retain and reinstall the original converter/resonator front section. Blanket no-cut promotional copy conflicts with this procedure.
Which body styles and years fit?MINI Cooper S 2014-2024 and John Cooper Works 2015-2024 with 2.0L turbo engine, subject to exact body/chassis and original exhaust connections. Primary says 2-door only; its manufacturer release lists F56 and selected F57 convertible applications, while the September 2026 manual says 2-door and convertible but starts at 2015. Retain the positively supported 2014 S scope with this source qualification. Confirm an F57 convertible directly against its exact year/engine and boxed instructions before ordering; no F55 four-door, Clubman or Countryman fitment is inferred.
Which adapter and clamp should be used?Select the S 2.375-inch-ID or JCW 2.75-inch-ID adapter to match the actual original pipe. Both adapters and two smaller clamp sizes are listed. The procedure generically says 2.75-inch clamp; resolve actual connection and correct supplied clamp before tightening.
Are all cross-brace bolts documented?Four spacers are itemized. Rear brace uses original bolts; the procedure calls for six new M8 front-brace bolts that are absent from the bill, with no length given. Confirm the boxed hardware and correct specification before disassembly.
Are six tips included?Only TWO carbon-fiber tips are selected. The black and polished part numbers in the shared bill describe alternate finishes. Each selected tip is 2.5-inch inlet x 3.5-inch outlet x 7-inch length.
What torque and recheck apply?Band clamps require 40-45 ft-lb after alignment, tightening evenly from front to rear. No separate brace, bracket, tip or flange numeric torque is supplied. Re-tighten clamps and hardware after 50-100 miles.
Are 9 HP and 14 lb-ft peak gains?At marked 3,412 rpm, selected run is 148.94 versus 139.81 HP, plus 9.13 HP, and 229.29 versus 215.23 lb-ft, plus 14.06 lb-ft. Separate maxima are 220.48 versus 220.23 HP, plus 0.25 HP, and 231.25 versus 221.57 lb-ft, plus 9.68 lb-ft. Thus advertised 9 HP/14 lb-ft represents the marked point rather than peak-to-peak.
