Okay, I am planning to get the jdm type r header and was wondering what catalytic converter would fit the 2.5" flange and still fit a EG b-pipe??? I don't really want a muffler shop to cut up my semi-new catalytic converter that i have right now. They did my old one and it leaked within a week. Thanks for your help in adavance.

 

good question. did you search? i would think it would be popular.
