I May be able to shed light on this, I have this swap completely done. 01 new edge 3.8 to 306 sbf t5 to 8.8
Im running e7s though for heads, since i already had the headers im not sure what they are from but I think they are fox headers. I also used a fox bbk x pipe as well and it all fit with ease. let me know if you need some pics.
