Oki have a 93 civic hatch cx, i am puttin a civic si (B16a) motor in it but i am not sure if the si header will match up to my A Pipe. I am gonna run the test pipe that came with my thermal exhaust. So my question is will a dc sports header match up with the test pipe????? Thanks for the help

 

I am gonna be running a dc sports header. I was wondering if i am gonna need to get a custom pipe to go from my header to where my cat should be. I am running a test pipe instead of my cat. Or are they possibly gonna line up?
Thanks

 

why not just bolt everything up and see what happens? they'll likely mate right up, and if not... thats what welders are for.
