I inspect them myself at work. But with my custom tune the rear O2's are deleted so when its hooked up to the emissions machine it still pass's as being just perfect. I still have the cat bodies so it looks legit and the bullet still constitutes as a muffler (i just put it on last weekend-helped with the rasp but not quite all of it-have a smaller Aerochamber on the way)

 

pretty easy -- don't have'em.

 

thanks, I figured friend of a friend was the answer!!!!
