| Manufacturer Part Number | 49-46111 |
| Product type | Catback |
| Main construction | 2.5-inch branches into 3-inch mandrel-bent 409 stainless. No unprinted welding process is promised. |
| Muffler and outlet | Dual-inlet/single-outlet 409 stainless muffler with plain Hi-Tuck over-axle/tailpipe. |
| Selected pipe identities | Left 05-144023, right 05-144024, muffler 05-144033 and tailpipe 05-144025. |
| Original bracket service | Reinstall front muffler hanger bracket with its two original bolts. Transfer the tail/over-axle hanger bracket in its original orientation and reinstall with three original chassis bolts. |
| Ground strap | Move the original ground strap out of the way during original converter-flange disconnection, then reinstall it on the driver-side lower flange stud during selected installation step 7 before tightening the four flange nuts. This electrical bonding strap is not a battery-disconnection instruction. |
| Front seals | The selected guide reuses the original four converter-flange nuts but does not print a gasket reuse/replacement instruction or list new gaskets. Confirm correct sealing service for the actual flanges before disassembly; no new-gasket or gasket-reuse promise is borrowed from another system. |
| Clearance and tightening | Selected guide gives tailpipe-to-body clearance of at least 1/2 to 1 inch and no numeric torque. Align and tighten converter flanges, then two 2.5-inch bands, then the 3-inch band. Retighten all exhaust components after 50-100 miles. |
| Power and sound | Primary claims up to +5 hp/+6 lb-ft, but links no selected chart to verify conditions, supporting modifications or point/peak values. Aggressive sound and reduced trail-contact risk are manufacturer descriptions, not measured noise, drone-free or damage-proof guarantees. |

It is the selected muffler-equipped 409 stainless Hi-Tuck cat-back for the listed Xterra 4.0L applications, using dual inlet branches and a plain single outlet.
Which Xterra applications are covered?The exact manufacturer identifies gas V6-4.0L Xterra 2005-2015. Match the named year ranges below; all five original groups already match. No other Nissan model or engine is inferred.
What components are included?one left mid-pipe 05-144023, one right mid-pipe 05-144024, one dual-inlet/single-outlet muffler assembly 05-144033, one over-axle/tailpipe 05-144025, two 2.5-inch bands 05-41061 and one 3-inch band 05-41055. No separate polished, black or carbon decorative tip is listed.
Which hanger brackets are reused?Reinstall the original front muffler hanger bracket using its two original bolts. Note the orientation, transfer the original tail/over-axle hanger bracket to the selected tailpipe and reinstall it with the three original chassis bolts. Retain rubber isolation mounts.
Where must the ground strap be restored?Move the original ground strap out of the way during original converter-flange disconnection, then reinstall it on the driver-side lower flange stud during selected installation step 7 before tightening the four flange nuts. This electrical bonding strap is not a battery-disconnection instruction.
Are new converter-flange gaskets included?The selected guide reuses the original four converter-flange nuts but does not print a gasket reuse/replacement instruction or list new gaskets. Confirm correct sealing service for the actual flanges before disassembly; no new-gasket or gasket-reuse promise is borrowed from another system.
What tightening and mileage check apply?The selected guide gives no numeric torque. After alignment and ground-strap restoration, tighten the four converter-flange nuts, then two 2.5-inch bands, then the 3-inch tail band. Maintain the specified at-least-1/2-to-1-inch tailpipe-to-body spacing and retighten all exhaust components after 50-100 miles.
Does Hi-Tuck mean guaranteed power, silence or damage protection?No. The primary claims up to +5 hp/+6 lb-ft without a linked selected chart, describes aggressive sound and says the Hi-Tuck layout reduces trail-contact risk. No measured every-vehicle gain, drone-free result or damage-proof guarantee is established.
