Which one is better?

it depeds on what you wantb for looks.

i have the blitz and i like it. its for sale but i dunno if it will fit an xA

If I remember right, most people say the blitz is pretty quiet, while the JIC is louder.

i want one that sounds balls, but I more importantly i want one that performs, I saw that the JIC adds 10-12 horses, how about the blitz?

eh... those exhaust numbers seem off. the blitz for me claimed 8-10 horse. i dont see it

i have the blitz and love the way it sounds and looks but never seen the jic intalled before though
