Alright so i just purchased a B18A DC header from a Friend
And thought it would fit on my B18B since they are both B18's

I bought a new gasket for it too
And i line them up together and not matching up





I also found out that the B18B A-Pipe matches up with the B18A

 

have you tried it on the motor ? or you just going by the gasket

all b series have the same exhaust flange

 

Yah right now im going by the Gasket
I havent actually have the time to put it on

So you think or know they should fit right on?

 

what brand of gaskets did you/are you purchasing?

 

I bought this kind from advance for 15 bucks
So it should be OEM
RIght?

 

i dont know if advanced auto parts carries oem honda parts. i doubt it is though. do you still have the box it came with? it would say honda on it if it was oem.

 

lol... you have to flip the gasket....

if look at the picture you'll see that on the bottom row of holes... one is higher than the other..

 

looks like its not going to fit either way... i would return it and get your money back. if you dont have a honda dealership you can go to, buy an oem one from hondaparts.com or inlinefour.com. oh btw, did you buy the exhaust manifold gasket for the b18b or b18a? remember, you get what you pay for

 

b18a or B18b... what does it matter really?

like stated above all b-series header flanges are the same.

 

and here's a picture to prove my point of having the gasket facing the correct way...

in the picture the OP posted... the gasket obviously matches the gasket in the picture below...

notice the bottom leftmost stud and how i said it was higher than the rest.

 

what a nice guy, took the time to take pictures and everything. you said it chief. wasnt trying to undermind you, sorry. i figured maybe he got a hold of one of those autozone like quality parts that has fitment issues. its happened to me in the past with a thermostat. never do that again. OP, please disregard what i said earlier.

 

Alright so i found the box and it says its Fel-Pro
Haha yah your right
Doesnt sound OEM at all
Ill return it and buy one from hondaparts.com

Thanks a lot guys!
Ill keep you updated

 

fel pro is a pretty good brand for gaskets

 

:werd: i've used fel-pro gaskets for the exhaust manifold (both the metal and fiber gasket) and other exhaust related gaskets without a problem...

i even re-used them once without a problem.

i don't really see why you would return it and then try and order it online and wait for it to be shipped...

 

Hahaha ahhh to late i already returned it

So do i even neeed a new gasket?

 

awww man, that was a perfectly good gasket. oh well, Fel-pro has been making gaskets for a looong time. i have also used fel-pro parts. sometimes a problem you have can be something so small its easily overlooked. wasnt even really a problem, all you had to do was flip it over. my bad on that advice man. ya live and learn.

 

I can always just go buy it again
Which i probly will
Hahah just gotta make sure the same people arent there
