Does anyone make a cat that goes from 2.5 to 2.25 instead of having to for example use a car sound cat and "adaptor", butchering the b-pipe.

I mean there's gotta to be a "cleaner" solution. i'm not looking for power beyond my stock cams.

i want to use a JDM 4-1 with a mugen twin loop.

perhaps a random cat?

 

i had my random cat for 2 months and it cracked 2 times, maybe i got a bad one,i don't know but it sucks

 

really? where did it crack?

 

the first and last weld,were it gets big and small don't know tech terms

I don't know of any cat company that builds a converter sized like you want. I'm not sure why they would even build it. It just doesn't make sense to make the outlet smaller than the inlet. Almost all the JDM headers have 65mm collectors so why would you run an exhaust smaller than that? I understand that the majority of folks who have a 60mm system will probably keep it but they should make that transition as smooth as possible from the cat to the B pipe.
