aFe ROCK BASHER Catback — Toyota Tacoma 4WD Double Cab

Tacoma ROCK BASHER high-tuck cat-back with turn-down tip

The aFe 49-46046 ROCK BASHER uses 2-1/2-inch mandrel-bent 409 stainless tubing, MIG welds, a muffler and a polished 2-1/2-inch 304 stainless clamp-on turn-down tip with laser-etched aFe logo. It ends near the muffler before the rear axle; it is not a muffler-delete pipe or a rear-side decorative-tip system. The exact selected guide specifies 4WD Double Cab/Crew Cab, 5-foot or 6-foot bed, 127.4-inch or 140.6-inch wheelbase, gasoline 2.7L or 3.5L. Its header ends at 2022 while the current exact manufacturer application rows extend to 2023. No Access Cab or 2WD approval is inferred from the broader model/engine headline.

FAQ

It is the selected 2-1/2-inch 409 stainless high-tuck cat-back with a muffler and polished turn-down tip for matching Tacoma 4WD Double Cab configurations.

The exact selected guide specifies 4WD Double Cab/Crew Cab, 5-foot or 6-foot bed, 127.4-inch or 140.6-inch wheelbase, gasoline 2.7L or 3.5L. Its header ends at 2022 while the current exact manufacturer application rows extend to 2023. No Access Cab or 2WD approval is inferred from the broader model/engine headline.

Use the supplied extension for the selected 140.6-inch wheelbase layout. Omit it at 127.4 inches. No extension trimming or cut length is printed.

one mid-pipe assembly 05-144229, one extension pipe 05-144230, one muffler assembly 05-144934, three 2-1/2-inch band clamps 05-41061 and one 2-1/2-inch polished clamp-on turn-down tip 49T25254-P09.

No. The exact manufacturer lists 49C46065 as a separately sold tailpipe upgrade. The selected standard configuration ends with its turn-down tip at the muffler.

Reuse the two front-connection bolts and factory gasket and retain original rubber isolation mounts. The selected guide releases four original hanger rods; the 14 mm reference is not a torque setting.

Selected band clamps use 40–45 ft-lb. Obtain factory-flange and actual tip-fastener specifications separately. Align away from wires, hoses, brake lines, body parts and tires; no fixed clearance dimension is printed.

Check for leaks during installation and repair any cause. Retighten all clamps and hardware after 50–100 miles. No exact selected dyno chart is linked, so no measured power gain or drone-free result is promised.

Installation Instructions

1. Confirm aFe 49-46046 against the exact vehicle and installed equipment. Inventory the actual components and follow the selected manufacturer instructions and current vehicle service requirements.
2. Match exact gasoline engine, named year, 4WD Double Cab body, bed and wheelbase. The guide header ends at 2022 versus current manufacturer rows through 2023; confirm any uncertain configuration before work. Cool and safely support vehicle and factory exhaust at proper vehicle-manual support points.
3. Lay out components. Remove the two factory front-connection bolts, retaining them and the factory gasket; release the four hanger rods from factory isolation mounts with the appropriate hanger tool. Keep new joints loose until fully installed.
4. Install the selected mid/front pipe with those two factory bolts and gasket. Their printed 14 mm reference does not give a torque value.
5. Omit the extension for 127.4-inch wheelbase; for 140.6 inches, place a supplied 2-1/2-inch band on the extension and slide it onto the mid-pipe. No trimming instruction is supplied.
6. Install the muffler using the original rubber isolation mounts and supplied bands, with the selected polished turn-down tip. Do not add the optional separately sold tailpipe to the included bill.
7. Align every component with safe clearance from wires, hoses, brake lines, body parts and tires. Tighten evenly front to rear: selected bands 40–45 ft-lb, with applicable separate factory-flange and actual tip-fastener settings.
8. Start the vehicle and check for leaks; determine and repair any cause, then lower correctly. Retighten all clamps and hardware after 50–100 miles. No battery, sensor, cutting or REBEL brake-cable-bracket procedure is borrowed.
