See my sig. I have the FRPP Stingers, same as the Borla (MADE by Borla) but with the "Ford Racing" emblem on the top of the tips. They sound awesome. I found mine about 10 months ago for about $425. The install was simple. TacoBill has a "How To" write-up on it.

 

+1 on the FRPP version. I love the sound and don't mind the drone.

I got them last fall for a little over $400 shipped. PM for link to site if interested.
