Hello, so I have had my 2015 with the performance pack for a couple months now. I put the roush axel back and ford racing x pipe on. I do not like the sound the X pipe puts out at all. Was gonna just re install the resonator the next day but my buddy already threw it out. So I took the X pipe out and had straight pipe put in instead. It's better better but it still has a lot of crackling sound at high rpm. I want to put the stock resonator in but am having difficulty finding one. Would even be willing to trade my x pipe that was on my car for less than 24 hours for one. Anyone help me out or have any ideas on how to get rid of the crackling sound?
