What up Moh!!?!?!
...as you know I did the AFE with the resonator delete Xpipe Mod..and then finished her off with the Supersprint.....
This is the bottom line.....The X runs a bit quicker........sounds way better than stock.....especially after having it on for 8 months....my bitch growls.....
.now then.....it does not and will not ever sound like a 4.8is......an 89 mustang gt.....or a ferrari....but it is definitley improved from the stock sound....which there was none
So..in the end I did it for some sound and looks....and minimal performance...
I hope that this helps..
