I have a set of DC 4to2to1 headers from my old 95 civic dx motor, now i am just wondering if these will fit on an 89CRX Si motor? And will I need to fabricate a pipe to have it fit it to the cat? and I have another question, i seem to have misplaced the 3 bolts needed to connect this 2 piece header together, I was wondering where i might be able to purchase these bolts or what would be a good replacement for them? let me know what you think...

 

suyre it will work should bolt up without any problems or fabrication......as far as bolt get some off Home depot or remove your old studs from your manifold and place them in the DC or call DC and get some new ones...
