Specifications
| Detail | Value |
|---|---|
| Manufacturer Part Number | 49-43041-B |
| Product type | Catback |
| Construction | MACH Force-Xp cat-back uses 4-inch mandrel-bent 409 stainless tubing, a free-flowing stainless muffler and one black powder-coated 304 stainless rolled slash-cut tip. The current primary and selected guide cover 2011-2014 F-150 3.5L twin-turbo EcoBoost. |
| Selected packing list | one mid-pipe #1 05-44633, one mid-pipe #2 05-44634 for longer wheelbases, one muffler assembly 05-44635, one one-piece over-axle/tailpipe 05-44636, three bands 05-41172 shown in the diagram, and one selected black 304 stainless rolled slash-cut tip 49T40501-B12. The polished alternative is not an additional included tip; no unprinted outlet dimension is inferred from the code. |
| Exact application restrictions | 2011-2014 F-150 gas 3.5L twin-turbo EcoBoost ONLY, with 145-, 157- or 163-inch wheelbase. No 2.7L, V8, Raptor or later-generation approval is inferred. |
| Source and packing gaps | The sheet labels step 5 twice: one entry addresses the longer-wheelbase tube and the next the over-axle/tailpipe. Treat both as printed entries. The front-pipe step says provided hardware but prints no complete front-fastener or seal bill; confirm actual packing and correct front-joint sealing service before disassembly. No new gasket or front-fastener quantity is invented. |
| Selected installation arrangement | Install the muffler using original isolation mounts, then mid-pipe #1. Test-fit the supplied longer-wheelbase tube 05-44634 before cutting: remove 6 inches for 157-inch wheelbase, leave it uncut for 163-inch wheelbase, and omit it for 145-inch wheelbase. Install the one-piece over-axle/tailpipe with original isolation mounts. This is supplied-tube trimming, not a stock-exhaust cut instruction. |
| Tightening and recheck | No numeric torque is printed. Keep joints loose until fully aligned, tighten from front to rear, keep the tailpipe at least 1/2 to 1 inch from body panels, and retighten all exhaust components after 50-100 miles. |
| Performance claims | The exact primary claims 32 hp and 29 lb-ft but links no selected chart establishing test vehicle, modifications, conditions or point/peak readings. No measured every-vehicle or drone-free guarantee is established. |
