Key Features

• Selected aFe part 49-36138-L.
• 2-1/2-inch mandrel-bent brushed 304 stainless main tubing with 100% hand TIG welds and factory-style flanges/hangers.
• Two selected 4-1/2-inch blue flame tips 49T25454-L07; each has a 2-1/2-inch inlet and 7-inch listed length. Alternative finish rows in the common bill do not mean eight tips.
• Six main pipe sections, two 4 x 19-inch resonators R49-91022, one 2-inch H-crossover band 05-41235, four 2-1/2-inch bands 05-41061, two gaskets 05-46326, four M10 bolts 03-50401 and four M10 nuts 03-50400.
• Two front flex sections with interlock liners and an integrated H crossover; the resonators are distinct from a supplied rear muffler. Original mid-pipe hanger brackets transfer and are reattached to the chassis.
• Current exact manufacturer and selected September 2026 guide support Nissan Z gasoline twin-turbo V6 3.0L, 2023–2026; named ranges distinguish Nismo and 2023-only Proto Spec.
• No cutting or modifications are stated; retain and restore original isolation mounts and applicable factory hardware.
• Tighten supplied band clamps to 40–45 ft-lb only; obtain exact service specifications for flange hardware, hanger-bracket bolts and tip fasteners. The current selected guide does not supply a V-band torque.
• Retighten all clamps and hardware after 50–100 miles; no fixed numerical clearance or guaranteed drone-free/power result is established.
• Gallery image 4 shows an alternative tip finish as an installed reference; it does not change the selected blue flame tips supplied.

FAQ

It is the selected cat-back for listed Nissan Z twin-turbo 3.0L configurations, with two blue flame tips and the exact selected sections described above.

No. This exact selection includes two blue flame tips 49T25454-L07. The common guide repeats alternative tip rows for separate finish variants; those are not eight supplied tips.

The full exact-MPN table confirms Nismo 2024–2026, Performance/Sport 2023–2026 and Proto Spec 2023 only. Match the exact twin-turbo 3.0L configuration; Proto Spec is not extended to later years.

This cat-back replaces the selected system after the original catalytic-converter flanges, including front pipes, resonators, mid-pipes and tailpipes. Original front hardware and transferred mid-pipe hanger brackets remain part of the installation.

The selected front pipes use original front-flange hardware. Selected tailpipe-to-mid-pipe connections use the two supplied gaskets and four supplied bolt/nut pairs. Both original mid-pipe hanger brackets transfer and reattach.

Tighten supplied band clamps to 40–45 ft-lb only; obtain exact service specifications for flange hardware, hanger-bracket bolts and tip fasteners. The current selected guide does not supply a V-band torque.

Manufacturer states no cutting or modifications. The selected guide prints no battery-disconnection or O2/catalyst service procedure; those operations are not borrowed from another system. Align, leak-check and recheck all clamps/hardware after 50–100 miles.

No selected measured dyno or drone-free guarantee is established. Manufacturer sound/design descriptions depend on the vehicle and remaining exhaust; tip finish does not prove a separate measured performance result.

Installation Instructions

1. Confirm aFe 49-36138-L against the exact vehicle and installed equipment. Inventory the actual components and follow the selected manufacturer instructions and current vehicle service requirements.
2. Confirm exact Nissan Z twin-turbo 3.0L, named year/trim and selected tip finish. Read the complete selected guide and inventory the actual selected bill. Cool and safely support the vehicle and original exhaust; leave new joints loose until the assembly is complete.

4. Install selected driver front pipe with original hardware, then passenger front pipe and its H crossover using the supplied 2-inch band. Fit one selected resonator on each side using one supplied 2-1/2-inch band per side.
5. Transfer both original mid-pipe hanger brackets to the selected mid-pipes. Join each mid-pipe to its selected resonator with the remaining 2-1/2-inch bands and bolt both transferred hanger brackets back to the chassis.
6. Install each selected tailpipe with one supplied gasket and two supplied nuts/bolts, restoring hangers into original isolation mounts. Install only the selected pair of tips.
7. Align the complete selected assembly with safe clearances to wires, hoses, brake lines, body and tires, then tighten front to rear. Tighten supplied band clamps to 40–45 ft-lb only; obtain exact service specifications for flange hardware, hanger-bracket bolts and tip fasteners. The current selected guide does not supply a V-band torque.
8. Start and leak-check, determine and correct any leaks, safely remove supports and retighten all clamps and hardware after 50–100 miles. No numerical clearance, battery/sensor procedure or measured performance guarantee is inferred.
