aFe Twisted Steel Headers & Y-Pipe SS 14-15 GM Silverado/Sierra 1500 V8 5.3L

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 metallic spun hi-flow (49 state legal or Canada legal) 300 CPSI catalytic convertors. The Y-pipe incorporates 3 in. down pipes from the manifolds to a 3-1/2 in. 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.
