After looking long and hard and some help from the cl-s forum I have found that acura exhaust is 1 7/8 inch. The problem is that I want a 2" muffler. Does anyone know do they make a fitting to make this possible and if so where do they sell it?

 

Check your local parts store they usually carry a great variety of adaptors to make this sort of thing possible.You can also go to local muffler shops they usually have a pipe expander handy that can accomplish the same thing.I have one of these things it works great.Jens
