aFe POWER Twisted Steel Catted Y-Pipe 3" to 3-1/2" Stainless Steel Exhaust 48-43004

aFe is proud to introduce a performance Y-pipe with catalytic convertors for the 2011-2014 Ford F-150 "Coyote" V8-5.0L. The Y-pipe is made from 409SS material for long-life and is mandrel-bent for maximum flow. Equipped with 2 high-flow 400 CPSI catalytic convertors. The Y-pipe incorporates 3" down pipes from the manifolds to a 3-1/2" merge pipe collector that connects directly to the factory location. The merge-collector is a mitered design, which reduces turbulences for better flow and performance over the tradition form collectors. Each Y-pipe mounts using all the OE locations for a simple clean installation. For maximum performance aFe recommends our V8-5.0L Twisted Steel headers P/N: 48-43001.

High-Flow catalytic converters:
The F-150 high-flow Y-pipe utilizes 400 CPSI cats, which keeps the system a true bolt-on and go solution. aFe installs the cats in the correct location, which eliminates any installation hassles.

True Merge Collector:
Eliminates dead space that can cause turbulence and hinder flow that formed collectors are prone to produce

Hassle-free installation

The F-150 V8-5.0L Y-pipe is designed to fit in the stock location incorporating the OE hanger, flange and 02 sensor locations.
