1) You got it right, just trim the midpipe and weld a flange on. You can probalby just reweld the same flange on that you cut off.xBenSETSfiRex said:I have a similar question.. I have a DX too, and i already have a catback exaust. When i put my headers on and get a EX cat, It would be too long for my exaust. So i would have to cut part of the exaust off and weld some flanges on right?
Also, isnt the o2 sensor in the cat? Would it run down below where the new cat will be, or would i have to get a new o2?
Is the tranny install difficult?

the guy that did my custom work used my old flex pipe insted of a flange and those spring loaded bolts. it works prefectly fine.
I have a stainless one in mind. Would a high flow cat be worth getting over a stock cat?klungemonger said:Just so you know, having two holes in the header won't prevent you from getting a CEL...if the secondary sensor isn't placed in or after the converter it will set a light off. The 2 holes are just optional locations to install the primary O2 sensor, since most of the OBD0 & OBD1 Civics had the sensor down at the end of the header, while the 96-up OBD2 models have it up in front of the motor. Whichever you choose, the other hole is supposed to be plugged off.
Don't buy a cheap chrome header, imo...those and the ceramic ones will rust. Get a stainless, you can get them on Ebay for about $170 shipped that's what I got and I like it alot.
