Hey all. I just wanted to let everyone know that it looks like aFe will be releasing a true 2.5" catback exhaust for the STs and other Explorer's/ Aviators with the 3.0tts. They told me they're looking to hopefully release it around the beginning of the New Year, sometime in January. They finished the redesign this week and I just got it back today. Unfortunately, SoCal rush hour traffic did not help with freeway speeds, but from what I can tell so far, zero drone. They just dynoed it today and I'm waiting on an electronic copy so that I can share it with you guys. From what I can make out, this exhaust made max power gains of roughly 17hp and 3lbs of tq, but throughout the graph made highs of 20hp and approximately 23lbs of tq over stock at about 4,500. These numbers are all on a stock ST. They have removed the resonators and chose to use a suitcase utilizing an internal X pipe. If I can figure out how to attach videos, I will try and do a cold start this weekend. It definitely sounds much better than the previous system with the resonators. Feel free to hit me up if you're in the SoCal area if you want to check it out. Again, I do not work for aFe, nor am I paid by them. I'm just their local guinea pig who likes the company and their products.
