Default Difference in headers and exhaust 94 L 99 RS

What is the size difference in the headers and exhaust between a 1994 L ej18 and a 99 2.5RS?

I have a 2.5RS swap in my L now with the stock ej18 system on there and it seems to be choking the motor up top. How much larger is the diameter on the 99 setup?

IIRC, its not much different, like .25". The headers are essentially the same, but the cat section seperates on some models and doesnt on others. The catback does have a difference.

I suggest just having a custom 2.25" catback made and using that.
