The Stainless Works Long Tube Headers fit the 2011-2014 Ford Mustang GT and replace the factory manifolds, cats, and H-pipe with a bolt-on 304 stainless system.

Install Difficulty: Professional Install Only
Long tube header installation requires a vehicle lift, O2 sensor transfer, and factory manifold removal; typically takes 6-8 hours. Post-install ECU relearn recommended to adjust for the higher-flowing exhaust.

Product Overview

This system uses 1-7/8in primary tubes feeding a 3in X-pipe with high-flow catted lead pipes that mate to the factory connection point.

TIG-welded 304 stainless construction with 3/8in thick flanges and 3in slip-fit collectors with merge spikes.

Backed by a lifetime guarantee for a durable, higher-flowing exhaust path from the head to the cat-back.
