Lucky for me I didn't have to deal with shrapnel as this was a concussive IED. That being said I have some muscle/nerve damage that to this day is still being worked out. My face is what took most of the blow. Lost some teeth, limited use of my jaw, and the TBI I said before. Good times.
I'll let you know how our quad exhaust endevour goes. Also making something up for the z4m.
And as for the Meth, I feel like I can get to the power threshold on the tranny without using meth. I also have E85 here which I can play with if I still have room to work.
