i have to smog soon and i dont have a cat at the moment...i'm currently searching for one that fits. [jdm type r]. but my friend has a 95 gsr exhaust manifold and cat that's pretty new. would the cat n manifold fit? and for the cat to work, do i need the secondary o2 sensor hooked up to the cat?? cuz i don't recall the test checking if it passes, just the sniffer on a 2 speed idle test. any help would be great...i'm going in on sat i think.

 

If you have an ITR it will not bolt on to your b-pipe. It would also be smart to hook up the second 02 so that your car does not throw a code.
