I have another question... i have a 66 289 (non gt) with single exhaust (originally had dual but someone changed it) I want to get the gt style exhaust that goes through the rear valance, but whar are the differences than the dealer installed besides the tips. Also what are some good systems that bolt up to tri-y's

There was a thread here a short while ago talking about the pros and cons of the trumpet exhaust. You might want to search on "trumpet" and read all the related posts before you make up your mind to change over. Going to dual exhaust makes sense, you just might want to rethink the trumpets.

I just installed Tri-Y's, dual exhaust and GT trumpets on my 66 a couple months ago. I found a good muffler shop that did all the welding, cutting and bending. I installed the headers. All went pretty well, until last week when the slat piece fell out of one of the trumpets! Running the car with one trumpet open and one with slats, I could definitely hear that those slats add restriction, sort of a "wheezing" through the slats. I'm now going to remove the trumpets and have some simple bevelled tips installed through the valence.

Good luck, you'll enjoy what the dual exhaust does for your Stang!
