Alright well ive got my headers coming in the mail and should be here in the next couple weeks. Im getting a custom y-pipe made to fit up with the headers.

A question arrised when i was told that im going to need to run dual cats in the y-pipe. My car is a 95 OBDI car and im almost positive i can run the cat right after the y-pipe and still be emissions friendly. He on the other hand has a 96 OBDII and i dont think he relizes that one yet.

Can anyone help me out here?

 

What kind of headers are your running? If you are running long tubes, then two cats may be a good idea simply because they will be placed alot closer to the header collectors and would be more efficient then a single cat sitting at the end of your y-pipe.
