I HAVE A 91 CIVIC WITH A LS MOTOR, GREDDY P.E. EXHAUST. I HAVE A B16A MANIFOLD ON IT NOW AND IT FITS PERFECT. I ORDERED A HEADER FOR A 92-93 INTEGRA LS, AND THE DOWN PIPE IS ABOUT AN INCH TOO LONG. ANY SUGGESTIONS WOULD GREATLY BE APPRECIATED!!

 

dc 4-2-1, kamikaze 4-1 this one is specifically made for a b series in EF, hasport also.

 

4-2-1 header

only a few 4-1 work unless you have a traction bar or notch your front cross member

 

FOR WHAT YEAR THOUGH, 90-91 IS DIFFERENT FROM 92-93

think about it... order one for the b16 if it fits perfectly.

 

NO CIVIC CAME WITH A B16, SO ITS A LITLE HARD TO LOCATE A HEADER FOR A 91 DOHC VTEC CIVIC

 

the kamikaze 4-1 clears like if not better than a 4-2-1 basically looks like a tubular equal length turbo manifold and goes into 1 tube downpipe half way down the block.

*think of an STD manifold with a straight pipe connected in place of cat to bottom half of manifold.

no civic came with an ls w/a b16 header either.... think about it man.... order the one for the b16(it will come in the same exact size as the one on your car now...that happens to fit perfetcly) order one for the 99-00 civic si, or the 95 del sol si... it is the same thing.

 

very good... but my car has a ls motor with a b16 stoch manifold that fits perfect because the b16 motor has the ls header on it in a da!!

 

if its an inch long get the 90-91 headers it should be shorter.... i would go either kamikaze or DC

 

THE STOCK LS MANIFOLD(1990) WAS TOO LONG THATS WHY I LEFT THE B16 MANIFOLD ON THE LS MOTOR

 

I was in the same boat...B18b w/ 90-91 header...it was too long.
I took it to a muffler shop and had them cut and flare the end. Fit it correctly and clamped it. Drove it to the muffler place and they welded it. Cost me $20 all said and done.

 

ORDER THE 99-00 CIVIC SI HEADER.... IT IS THE SAME DAMN LENGTH AS THE STOCK B16... PLEASE READ. I HAVE A 99-00 SI DC HEADER ON MY CRX WITH AN LS SWAP AND IT FITS FINE.
