I am thinking about buying longtubes in the very near future but I have a couple of concerns. First, I have a Bassani Catted X-pipe and a Borla XR1 catback, and like the idea of not having to change that. How much power gain would I get putting shorties on the current setup I have? What about the gain with LT's? Could I modify the Bassani piece to fit or would I be better getting a special "shorty" X-pipe?
Also, how much am I looking at for an install? I don't really want to tackle that job in my own garage.
