Anyone try a set of these ?

I run the 3" version on my street 64. 413/Mopar 509 cam/headers/h-pipe/turn-downs by the door.

They are quieter than open pipes. No problems with cops. And it is nice to be just a little louder than all the jokers around here in the 5.0 rustangs.

My only complaint is that (at least on my setup) at high RPMs, it is a little metallic sounding for my taste. As a pose to being more throaty.
