Headers and cats need quick help.
 
So I bought a set of pacesetter headers, long tubes, they came 3 inch outlet (ID,OD???), and I found a set of 3 inch (inner diameter) catalytic converters.

Does anyone know if the pacesetter headers are 3 inch inner diameter or outer diameter? and would these cats slip fit on the headers?

They are 300 cells.. Would 200 cell be more benefitial? they're going to be right at the end of the headers. After cats will be offroad y pipe.

Thanks!

any muffler shop will make it fit.. I have 3" pacesetters and my muffler guy just cut the ends of my cats to make them have 3" openings on either side and then just ran 3" piping all the way to muffler...

I first had it welded on and then later decided to have them flanged so I could take them off every other year for smog tests...then I put real cats on :)
