Do anyone know if I can use a stock 88-91 si header on a 97 civic cx block? Had my 91 crx hf swap (not by choice) with a 97 cx engine/block and 88-91 si tranny and it's got the cx headers I believe but now that I'm trying to "build"/piece up my crx to how I want it to be I want to put my greddy sp2 exhaust on there and because I HAD a HF engine I couldn't because of the header. But now with the swap I found a Si header and want to know if I can use that and then put on my greddy exhaust. Well let me know because I really like to put it on and get going on building my rex LMK TIA


Current header:

 

yes a si header will fit fine

 

Thanks will pick one up then...just didn't want to buy an aftermarket header since I might not be keeping the SOHC for too long....plus not worth it unless I do a rebuild or something....but got bigger plans down the road(if all goes well)....but thanks man...anyways kind of nice to be back on HT has been a while/been busy and might not be back for a while again Anyways thanks Jimmy!
