Ok i'm buying the random tech cat for my 01 civ ex. Will the dc sports 4-1 ceramic header work with it and if not what will cuz i've heard that i need to upper half only which doesnt seem to exist. Someone point me in the right direction
Thanks,
Shane

 

The random tech cat will just replace the stock cat. So will the header.

 

The random tech cat, replaces the cat AND the header "B" pipe, so if you get a 4-1 1 piece, enjoy having someone cut and weld **** together.

You need something like this

 

the part number and price of that one are of the whole 4-1 header so i mean if i bought that exact one from that site would it work with the random tech cat.
