So far the best upgrade I have done yet. The catless downpipe really lets you hear the turbos spooling up, it sounds like my diesel work truck. With this pipe and a tune and the truck has become an entirely ...

Installed on my 14' ecoboost and I love the way the turbos sound now. Still have the stock exhaust after the downpipes (for now). Install was easy-ish...just need the right extensions and universal adapters. ...

    fantastic upgrade

    So far the best upgrade I have done yet. The catless downpipe really lets you hear the turbos spooling up, it sounds like my diesel work truck. With this pipe and a tune and the truck has become an entirely different animal. I have been enjoying every minute of it, my tires on the other hand have been paying the price. The build quality of the Stainless Works is top notch I'm very pleased with the fit and finish of their product. I would recommend it to anyone looking to boost power and give the truck a much different sound. The install was not to bad it took about 2 hours.

    Singing turbos

    Installed on my 14' ecoboost and I love the way the turbos sound now. Still have the stock exhaust after the downpipes (for now). Install was easy-ish...just need the right extensions and universal adapters. Would really suck if the bolts were rusted on though. Had to unhook my rear stock exhaust hanger to get it to fit up to the downpipes, which was a PITA. Other than that I've been enjoying them!
