2012 FX4 5.0, phase 2
So months ago I had the Roush calibrated blower kit put on my truck, and this week I finally had my exhaust done to finish it off (along with the 85mm pulley upgrade for the blower). This consisted of ARH headers (1 3/4" primaries) with high flow cats, the Magnaflow Off Road Pro series catback exhaust (part #17137), and a custom tune from Cody at Stang Hi here in Baton Rouge. He also put my stock resonator back on to help with drone, as this system is a turn down in front of the rear axle. Here's some pics of the exhaust and dyno graphs. The first 2 are with the exhaust, new pulley, and custom tune. Towards the bottom is my original graph going from stock to the less than stellar Roush tune. He had to do the dyno pulls in third gear, I believe due to the size of my tires (said something about the truck hopping around). Final numbers were 488HP/452ft-lbs torque w/ 10.5 lbs boost. Truck sure has come along way, not too bad for a big 4x4 with 35's on it. Working on getting a video on youtube for anyone that would like to hear how it sounds. The 2 new graphs are somewhat blurry for some reason when i upload em, sorry =(

Video doesnt really do it justice, but it sounds really good imo. Be sure to watch/listen in HD.
