I was interested in putting a cutout in place of my cat. If I remember correctly, my y-pipe is 2 1/2" and then I have a 3" pipe that is on the other side of the cat that leads to the muffler. Does anyone sell a cutout that changes from 2 1/2" to 3" or would I have to have buy a cutout and have an exhaust shop fab something up to make it fit from the 2 1/2" to 3"?

 

Buy a 3" cutout, it will slip over the pipes and weld right into place, thats what I did and it worked like a charm.

 

yeah he is right. or go to a good muffler shop and they can make it fit perfect!
