ZZP Ecoboost 3.5L F150 Downpipes Bolts Uses 52mm or 2 1/16"This is ZZP's first product for the 2011 2014 Ford Ecoboost V6 F150's. The stock downpipes are quite restrictive the F150, so we developed our fully mandrel bent set of pipes in house. These downpipes come with a pair of high flow catalytic converters. Not only will these make your truck sound better and give you more turbo whistle, they flow significantly better than stock and help reduce KR. We saw gains of up to 55whp and 51ft lbs when installed
