The aFe 48-46006-RC is a catted, twisted-steel Y-pipe for the 4.0L V6 in the 2005 to 2015 Toyota Tacoma, built from 2 IN to 3 IN 409 stainless steel. The manufacturer says it uses factory style hangers and flanges and is designed to fit the stock locations with no cutting or modifications. Its tubing is 100% MIG-welded, so buyers looking for a bolt-on 4.0 Tacoma exhaust upgrade get a model-specific piece rather than a universal fabrication project.
Owners on user forums describe the routing as better than stock, though one reports a very raspy note even with the stock muffler. Another owner argues that it doesn't actually reroute the exhaust and still hangs under the frame, so opinions vary and clearance should be confirmed before buying. Owners also note that the first CAT you come to is part of your Y-pipe, which makes this a meaningful emissions-equipped swap rather than a simple pipe replacement.
The manufacturer lists the 2005 to 2015 Toyota Tacoma with the 4.0L V6 for both 2WD and 4WD applications. Trim-level listings vary, so confirm fitment with the manufacturer using your VIN before ordering.
The manufacturer states that the pipe uses factory-style hangers and flanges and is designed for the stock locations, with no cutting or modifications required.
Owners on user forums disagree. Some report routing that is better than stock, while others say the pipe still hangs low under the frame. Check clearance with the manufacturer if you have a lowered or off-road setup.
Owners on user forums who installed an aFe exhaust system recommend reading the instructions first, getting the truck safely on jack stands, and soaking every fastener in penetrant beforehand. One owner used an offset grinder with a metal-cutting blade to ease removal of stubborn components, so keep one on hand for seized parts. Because the Y-pipe carries the first catalytic converter, expect to unbolt the upstream and downstream flanges and the stock O2 sensor connections. Owners also report that corroded header flange studs can turn a bolt-on job into a long cut-and-drill session, so budget extra time for rusty hardware.
