First of all, I am new here. I've been a reader for some time, now decided to become a participant. Great forum! I enjoy the respect and support seen here. Anyways. . .I have a 94 del Sol VTEC ( B16A3). I was wondering if a DC Sports Header 4-1 from a Civic Si would fit my car. I still have my cat. I would believe that any difference in exhaust would only be after the cat, since the car may be longer/shorter, but I rather ask you guys, since I tried the search function and pretty much read every header involving thread here! Anyways, thanks in advanced!

 

it is the same

 

Thanks a lot man! Im about to head out to a friends house to mount it on! Thanks for the great help!

 

The header will work as long as the civic si has a B-series in it or its a 2k si. If its a D-series, it wont work.
