Peace, mercy, and blessings of God be upon you... Hello everyone. I have an F150 Ecoboost 6 twin-turbo cat-back, and I believe it fits the 5.0 V8. Its sound is quiet from the outside and not annoying inside the cabin, and at the same time, it gives you an amazing sporty sound. I have a video of it for whoever wants it. The large muffler is Magnaflow 22 inch straight through, and the resonator is Dynomax 24215. The original one is included with the sale. The cat-back is custom-made. It's excellent for those who want the car to breathe better without noise or traffic problems. As you can see, it's removed and ready for immediate installation. Excellent for the 6-cylinder, and I believe it will be even better on the 8-cylinder. Please, offers less than 800 SAR, I apologize, as I am losing money on it, and all its welding is laser. May God grant us and you the best.
