I just ordered a b16a from hmotorsonline.com and wanna put a dc sports header on it im just wondering what year of car I look for that will fit the engine and if it will mate up to my 89 crx si catback stock or if I will need to shorten/lengthen the cat to meet the b16a exhaust.

Thanks for any help.

 

Get one for a 99-00 Civic Si. It will mate up fine to your stock cat just fine. One last thing, PUT THE HEADER ON BEFORE DROPPING THE ENGINE IN! You will see once you get it in how much time that just saved you.
