Ok so on my 99 turbo my exhaust started falling apart and i purchsed a jdm performance exhaust the inlet is 2.25 my cat and downpipe is now also broke and fell apart while my new exhaust came in the mail now I don't give a rats about emissions I was looking at Megan's racing downpipe looks like that takes out the cat but the downpipes i find anywhere have a 2.5 to 2.5 or 3.0 size so I'm confused as to weather that will work cause I got a 2.25 inlet
 
im not sure if i get what your asking.
are you talking about the O2 housing exit being 2.25" and want to know if a 2.5" or 3" downpipe will bolt up to it?

Yes dusty that's what im asking
 
a full 3" won't fit. If its got a 2.5" inlet will work.
If your car is an AWD and you wanna ditch the cat, Punishment Racing has DPs for $100
