American Racing Headers Long System, 1-3/4" x 3", 2014+ GM Trucks 5.3L - Catted

It didn't take long after the release of GM's 2014 trucks with Direct Injection V8's to realize they are a great platform for added performance and efficiency. There was no doubt these trucks will benefit greatly from a quality set of 100% US made long tubes and Y-pipe from ARH. What kind of benefits? With tuning, well over 30 Rear Wheel HP and 30 Rear Wheel Torque are achievable, which will also improve fuel mileage and the ability to pull that trailer down the road. Available primary sizes are 1-3/4" or 1-7/8" and our direct fit Y-pipe is 3". With 304 S/S used throughout, these ARH systems are built to last indefinitely. Other features include, 3/8" thick flanges with tig welded and hand ported inlets, merge collectors with scavenger spikes and leak free ball socket connections.   Features: 100% Made in the USA - Never Outsourced Made entirely of 304 stainless steel  3/8" thick laser-cut flanges for a warp-free seal Hand-ported TIG welded inlets Optimized primary tube routing for superior fit and performance Merge collectors complete with welded scavenger spikes Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability
