Ok, I just bought a dc sports 4-2-1 ceramic header. 1 piece.

Theirs no o2 sensor hole on it like my civic has.
Is this a basic bolt on install, remove oem header, put on dc header?

Im hearing that their is a gap wen i install the dc header from the header to the exaust?
that im going to have to buy a test pipe and put that together and make a o2 hole for it?

Am i going to be still using the oem cat?

Somone help me out. tell me whats going to happen. Thanks.

1. Basic bolt on - yes
2. Gap - depending..some have a gap, some don't (between brands). Not really sure about DC
3. OEM cat - I was able to use mine..

 

i assume you have an LS? did you buy a gsr header? if so, then no, there would not be an O2 bung because gsr's have it on the cat, and yes, there will be a gap since gsr headers are shorter than LS headers.
