Just had my SMA exhaust installed last weekend. Initial thoughts:
I can definitely feel a little bit more "giddyup" with them (Yeah, I know, this "expert" over here can tell the difference with a few more HP's added !!), although it isn't much it seems to help a little bit.
The cabin noise has increased about 5x what it was before (what?? Did you say something?? Sorry, I can't hear a thing with this humming in my ears !!) so I'm going to look into trying to add some sound deadening material somewhere or just turn up the tunes!
For someone really into trying to squeeze a little more HP's out of it, it might be a decent upgrade.
But, of course, just my $.02.......
