Borla sent me this::::Thank you for contacting BORLA PERFORMANCE. The main difference is the 140086 versus the stock system is our system is made to out perform the stock system and to never be replaced. The system we offer for your vehicle has all manderal bent pipe and a completley straight through muffler to give you optimal performance. The other system we offer for your vehicle has the same pipe bends and straight through muffler but just hass two outlets instead of one. If you do a lot of towing I would stay away from the dual system for the reason that you will have all of the exhaust gasses going all over what you will be towing. I hope this helps. Your stock exhaust system has crush bent pipes and a baffled muffler which impead that flow of your exhaust locking up hp and torque that you should be using. If you have additional questions regarding Borla exhaust check out our web site www.Borla.com you may contact me Direct anytime Mon-Fri 8:30-5:00 PST with questions or concerns

Regarding our products.::: If this can help

 

That's funny -- my wife tells me that I spend too much time on this forum as well...

 

FYI... the Roush exhausts for the New style F-150s are made by Borla and can be purchased from Woodhouse for around four and a quarter plus shipping.

 

Hmmmm, 4 and a quarter isn't bad at all.
