Review on Gibson 789800S Superflow Stainless Performance by Robert Gilbert
2018 F150 3.5 Ecoboost works great
Installed 2018 F150 3.5 Ecoboost works great and sounds great, rear wheel off. I don't usually write reviews but I love Gibson here and the only way to put a dual exhaust on an Ecoboost that isn't too loud or really harsh is to use it. It sounds a little raspy at very high rpm, but that's just the nature of the 3.5 Ecoboost beast. But on startup it sounds very raspy and almost like a V8. Use a good place to install/weld mufflers/pipes and you'll be fine.
