I'm trying to decide on an exhaust - and everyone seems to like the T1R, but when I do a search in google, some seem to be dual and some seem to be single?

Is dual an option? What would the difference in performance and sound be?

The dual's are are called the Sparrow's. They make 63mm and 70mm dual. You've got 63mm Sparrow, the 70mm Sparrow and the 70R-EM Sparrow.

I have the 63mm Sparrow and love it. Not to loud, not to quiet.

Any difference in performance in dual and single?

I prefer dual from a look point of view.

The singles I think are suppose to give you a couple more hp's, but most are LOUD and like you said, I like the way the duals look anyway.
