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 or in an off-road catless version. 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 and dyno-ed in house without a tune on the catless downpipes. As you can see from the dyno sheet they pick up quite a bit of mid range and upper end power and torque. Look for similar gains with the catted version. Our downpipes are also significantly lighter than the stock unit.
