Overview

Improve the power and performance of your 2011–14 Ford F-150 3.5L EcoBoost with a premium downpipe system from Stainless Works. This 3" downpipe will maximize exhaust flow and includes a Y-pipe to connect to the stock exhaust or most aftermarket exhausts.

Designed for the 3.5L EcoBoost engine, this downpipe features high-flow catalytic converters and a factory connect Y-pipe for a direct bolt-on installation. The 3" diameter tubing significantly reduces backpressure for faster turbo spool and improved throttle response.
