Hey guyz im new, i got winter beater 94' Intrepid w/ a 3.3l and a MAD custom intake! :)

But what i really want to know is the exhaust size from the two pipes that go into the cat, and what size is the one pipe comeing out the back of the cat? My cat is clogged shut so im putting a "Y" pipe in there to replace! Has any one ever did this? is it loud or what?

Thanks!

Both ways? i would say the 2 pipes from the headers are smaller then the one coming out not? I would say the one comeing out is 2 1/4 maybe but in id say 2 TOPS! but i could be wrong!
