i swapped in a fresh d16z6 into my 95si today and while i had the exhaust dropped i figured id take a look inside the ca because my car was extremely loud. i found what i figured i would it had been broken out inside and is now basically a test pipe. i did a little searching and found on on a 4 dr civic i think like a 93 its the same era now does anyone know if these are supposed to be the same length and everything between hatchback and sedan cat. converters? thanks in advance

 

it should be, you could look it up on parts sites. The difference in length comes from the exhaust pipe and not the cat i believe

 

The hatchback cat converter part number:4873638
The 4 dr cat converter part number:84130

 

Call your local dealer with those part numbers.
