| Manufacturer Part Number | 49-43081-B |
| Product type | Catback |
| Construction | 3-inch into dual 2.5-inch mandrel-bent 409 stainless, MIG welded. |
| Selected bill | one mid-pipe 05-144149, one 21-inch extension 05-144139, one muffler assembly 05-144147, one tailpipe 05-144148, four 3-inch bands 05-41055 shown in two pairs, two 2.5-inch bands 05-41061, one hanger bracket 05-46190, one isolation mount 05-46050, two clips 05-60104, two M10 bolts 03-50418 and two selected black 304 stainless tips R49T30352-B09. The polished alternative is not an additional pair. |
| Cab and equipment scope | The primary lists Crew Cab/long bed 157-inch wheelbase with 6.5-foot bed, Extended Cab/short bed 145-inch wheelbase, Crew Cab/short bed 145-inch wheelbase with 5.5-foot bed, and Extended Cab/long bed 163-inch wheelbase with 8-foot bed.

| Guide clarification | The guide calls for hanger bracket #2 in step 8 but formally identifies only bracket #1. It also calls for provided front-flange bolts/nuts without a complete separate allocation, while the bill lists two M10 bolts and clips. Confirm the actual bracket arrangement, matched hardware and front-flange packing before disassembly; do not invent a second supplied bracket or extra fasteners. |
| Configuration-dependent installation | For Crew Cab/short-bed 145-inch wheelbase and the guide procedure's Extended Cab/6.5-foot-bed case, install the muffler without the extension, subject to the cab/bed conflict above. For Extended Cab/long-bed 163-inch wheelbase use the 21-inch extension; for Crew Cab/long-bed 157-inch wheelbase trim that supplied extension to 15 inches. This is extension-tube trimming, not a stock-exhaust cut instruction. Relocate the original hanger bracket to the first set of holes inside the frame as shown in Figure B. |
| Tightening and recheck | No numeric torque is printed. Keep joints loose until complete alignment, tighten front to rear ending at the selected tips, maintain the guide's tailpipe-to-body spacing of at least 1/2 to 1 inch, and retighten all clamps and bolts after 50-100 miles. Brief smoke at initial startup is described by the guide. |
| Sound and performance | The primary claims up to 9 hp and 17 lb-ft from in-house testing, but links no selected chart establishing the test vehicle, engine, modifications, conditions or point/peak readings. Those remain manufacturer claims, not a measured guarantee for every listed engine or truck. |
| Emissions statement | The manufacturer says no CARB EO is required for this product. This does not approve unrelated exhaust modifications. |

That cab/bed wording conflict requires exact aFe confirmation before ordering or work; do not infer every listed Extended Cab/short-bed configuration is cleared. Side steps may interfere.
What parts are included with the selected finish?one mid-pipe 05-144149, one 21-inch extension 05-144139, one muffler assembly 05-144147, one tailpipe 05-144148, four 3-inch bands 05-41055 shown in two pairs, two 2.5-inch bands 05-41061, one hanger bracket 05-46190, one isolation mount 05-46050, two clips 05-60104, two M10 bolts 03-50418 and two selected black 304 stainless tips R49T30352-B09. The polished alternative is not an additional pair.
Which hardware or specification detail needs confirmation?The guide calls for hanger bracket #2 in step 8 but formally identifies only bracket #1. It also calls for provided front-flange bolts/nuts without a complete separate allocation, while the bill lists two M10 bolts and clips. Confirm the actual bracket arrangement, matched hardware and front-flange packing before disassembly; do not invent a second supplied bracket or extra fasteners.
How do extensions and original mounts apply?For Crew Cab/short-bed 145-inch wheelbase and the guide procedure's Extended Cab/6.5-foot-bed case, install the muffler without the extension, subject to the cab/bed conflict above. For Extended Cab/long-bed 163-inch wheelbase use the 21-inch extension; for Crew Cab/long-bed 157-inch wheelbase trim that supplied extension to 15 inches. This is extension-tube trimming, not a stock-exhaust cut instruction. Relocate the original hanger bracket to the first set of holes inside the frame as shown in Figure B.
What tightening and follow-up checks apply?No numeric torque is printed. Keep joints loose until complete alignment, tighten front to rear ending at the selected tips, maintain the guide's tailpipe-to-body spacing of at least 1/2 to 1 inch, and retighten all clamps and bolts after 50-100 miles. Brief smoke at initial startup is described by the guide.
Is cutting required?The primary states no cutting, but the selected guide explicitly requires trimming the supplied extension to 15 inches for Crew Cab/long-bed 157-inch wheelbase. No stock-exhaust cutting is specified; confirm the actual cab/bed before work.
Are gains or drone-free operation guaranteed?The primary claims up to 9 hp and 17 lb-ft from in-house testing, but links no selected chart establishing the test vehicle, engine, modifications, conditions or point/peak readings. Those remain manufacturer claims, not a measured guarantee for every listed engine or truck.
