I have the Borla TT exhaust on my 93 N/A.
Differences:
The only real difference is that the TT exhaust has one less muffler, so its louder.
Installation:
The only problem you'll have is that you have to weld one extra hanger. If you have it put on by an exhaust shop, they'll tell you that it needs another hanger, and they'll weld it on for ya. I paid $100 to have mine installed. Took like 2hrs or so (before my friend dropped my car back off, finished).
