Guys, I'm about to purchase a pair of cat converters and I want to make sure I get the right size. I currently have Pacesetter headers with their y-pipe, but I couldn't find information on the size of the y-pipe.

I'm assuming that the y-pipe is 2.5" and meets the 3" collector....correct? Is 2.5" the standard size?

Thanks...

Interesting. Are most y-pipe for our cars 3" then?
