Well i've had the mufflers for a few months now and i just scored the tail pipes to go with them from the same guy i got the mufflers off of (i now have $50 in a $480 cat-back..lol) and i'm very pleased. I may actually pass on getting the Spintechs now. I'm running them with MAC full lengths and a Dr. Gas offroad X pipe and they sound amazing....completely different than the clips i've heard with them ran with an H pipe. I think they're about as "DOHC 4.6" as i've ever heard on a 5.0. My only gripe is the way the tail pipes look...they're the chrome tips and i don't like how you can see where the chrome stops (as opposed to MAC which are chrome all the way up under the car) but the up side to that is the tips are fully adjustable and you can adjust them perfectly the way you want and it's a lot easier than adjusting MACs (which is pretty easy to begin with). The best part is that they're smooth and mellow sounding at cruising speeds but scream like hell when you mash the gas...perfect for keeping a low profile around the popo 
I'll try to get some clips up tonight or maybe tomorrow.

Sounds pretty good imo.
