Vastly Improved Power without Rasp

The most restrictive part of your 2011 to 2014 EcoBoost's exhaust system is its downpipes and Y-pipe. Their small diameter and inefficient factory catalytic converters choke your 3.5L EcoBoost V6 off from making more power, especially if you've stacked on other modifications and tuning. Stainless Works' catted EcoBoost downpipes free up much of those restrictions and greatly reduce back pressure to give your powerful truck a massive improvement in horsepower and torque output, especially in conjunction with other modifications and aggressive tuning. Stainless Works' downpipes are a perfect way to push your truck's EcoBoost motor to its absolute limits and get the power and vicious sound you'll need to conquer the streets or off-road trails.

Includes High-Flow Cats and Y-Pipe Connection

The kit consists of two catted downpipes and Y-pipe connector for your cat back that measure 3" in diameter. Stainless Works carefully mandrel-bends all of this kit's exhaust tubing to ensure smooth outflow and to maximize power gains. Further reducing back-pressure are two high-flow catalytic converters that are are far less restrictive than your stock converters and also help avoid a raspy, whiny exhaust note that's common on off-road downpipe kits. This whole system is made out of high-quality 304 stainless steel that's resistant to corrosion and discoloration in any climate. These down-pipes are bolt-on replacements for stock and can hook up to your factory cat-back and stock-sized aftermarket cat-back systems.
