I just got rksport headers and this y pipe.

http://www.slobird.com/ypipe.jpg

It is a 2.5 in and 2.75 out. I would like to :

Have a cat that will bolt on to this pipe and the stock exaust.
Make a straight pipe that will bolt on in place of the cat.

?1. Does anyone know of a cat that will bolt on?
?2. If not what kind of flanges (name) do I need and where to get?
?3. What kind of flanges for straight pipe
I have a welder and sawsall so can make stuff.

Also I expected to find an 02 sensor downstream of the Cat, but did not. If I just put the stock o2 sensors back in shouldn't I be able to run with out a cat and no codes?

thanks!

You cannot buy a highflow cat that will just bolt on because the bck of the cat is welded to the Ypipe. However this place sells high flow cats as well as straight pipes. (http://www.fasttoys.net/8292fbodyexhaust.html) they are for a 3rd gen so you might have to fab a little but it would be a good start.
