I have a 92 civic cx and have purchased a DC JDM header for my b18c1 engine. I also purchased a Greddy Catback.

Does anyone have a similar set up? I'm sure someone must it seems like a common enough swap/common header choice.

Please let me know the length of the catalytic converter. I'd like to order a carsound cat with welded flanges that fills the correct amount of space w/o problems.

I could have a cat made at a shop but I dont know of any good performance shops that would construct a good SS cat for my set up with flanges for both the header and the catback (different style flanges).

Also. If the header has a 2.5" collector and the exhaust is 2 3/8" (but bolts up with 2.5" stuff) should I get a 2.5" high flow cat, or would a 3" work and have better flow??

 

this has to be common, anyone?

 

you should get a 2.5 catalytic converter for your setup. now, the best way to have all these parts come together is a muffler shop. they can make everything fit: from gasket to flanges whatever else you need.

 

uhhh.... of course. however, i'd like to know the length of the cat, thanks.

is it the same length as the stock dx, si cat? I have a catback for the dx, si hb.
I was under the impression that the ls,itr, si headers were long enough to reach the factory size converter. the gsr header was about 4-5" too short.

thanks
