Need some help guys.....the flange on my stock civic cat (EG 92-95) broke and now the cat hangs down to the ground and my car sounds like a freakin cessna. The car is still stock (D series) but I have an B series setup with a USDM Type R exhaust manifold that will be bolting in sometime in the near future. So my question is if I replace the cat with a civic one, will it bolt up to the type R header, or do I need to buy an integra cat to work with the header? Thanks in advance.
