2011-2014 F150 3.5L Ecoboost Stainless Works S-Tube Turbo Cat-back Exhaust Kit FTECOCB-LMF

Loud and Aggressive Exhaust Note

The Stainless Works S-Tube Turbo exhaust kit is one of the leanest, meanest, and high-quality EcoBoost cat-back systems that you can find on the market and is guaranteed to give your truck a vicious roar and some spare horsepower and torque, to boot. The S-Tube is one of Stainless Works loudest, raspy, and aggressive EcoBoost cat-back exhausts that add a vicious growl and wicked turbocharger whine to your 3.5L V6's exhaust note to instantly make your truck more menacing. This cat-back exhaust system is also much more efficient than your factory system and will help improve horsepower, torque, throttle response, and fuel mileage all in an easy bolt-on replacement.

Mandrel-Bent 304 Stainless Steel Tubing

The Stainless Works S-Tube cat-back exhaust is built from the ground up for both quality and aggressiveness. Each system is built entirely out of 304 stainless steel that's resistant to corrosion and discoloration in just about any climate. The kit uses 3-1/2" mandrel-bent tubing to ensure much more efficient exhaust outflow with less restrictions than stock for all-around performance gains. The system bolts on right in place of your factory cat-back and can hook up to your factory downpipes, Stainless Works' Catted Downpipes without modifications. The kit comes with your choice of a black or polished 3-1/2" slash cut exhaust tip, options for which are available from our drop-down menu above.

This cat-back exhaust kit deletes your factory resonator for a more aggressive tone.

Wheelbase Fitment: this Stainless Works cat-back will only fit trucks with up 157" wheelbases and will not directly fit trucks with 163" wheelbases (SuperCab with an 8' Long Bed). Call 1-877-578-2433 for more information.
