New to the Honda scene.
Just picked up a 1989 Civic Si, and am trying to improve it on the cheap. The exhaust system needs to be replaced, and I want to upgrade. It seems wrong to install a 2.25-2.5" exhaust system to the 1.5"(?) exhaust manifold pipe. Is there another Honda model with a bigger/better flowing exhaust manifold that would fit the D16A6? I would like to avoid going to a header due to the cost and non-stock appearance.
Thanks for the help.

Yup.. you can use a late model d16y8 exhaust manifold.. it's pretty much a 4-2-1 header.
You will have to modify it a little bit (a little of the ol' cut n paste) but it's not that hard.

or, you could buy my already modified d16y8 exhaust manifold that I am no longer using

 

if riley doesn't jump on this, how much are you asking for the y8 manifold? I have an A6 that i had to cut the manifold to get out of the engine bay due to rusty bolts and will need a new one

 

How big is the Y8 supposed to be, the inner diameter?

 

the Z6 is the same as the Y8

Wrong.

 

How much would to want for the modified D16Y8 manifold?

Thanks

50 plus shipping.

I'll tell you now. it's not pretty, but it does the job and flows a lot better than the a6.

 

bump. Any other bolt on ideas?
Thanks again. Wolfriley

Go buy a cone filter and rig up a cheap ram air intake where your stock airbox resides.

 

Everything you need to know about the d series headers...
