I have yet to find a 4-2-1 race header made for the 01-03 civic ex. Right now I have a 4-1 Megan Racing exhaust header, attached to a Megan downpipe. I need a 4-2-1 long tube race header to cut out the really little exhaust leak I can not get rid of between the manifold and the downpipe. Has anyone found what I need?

 

I don't think the 4-2-1 will solve your problems. Your problems lie within Megan Racing's build quality.

 

Google it.

I did google it, and nothing turned up. That is why I turned to yall's help.

 

dc sports makes a 4-2-1 race header for the d17. I have one and love it.

 

here's a link

Thanks. All your posts were very helpful!

 

Why buy a new manifold, when you can just replace the leaky gasket?

 

 

actually you can no longer put the oem bolts into the megan header. They stripped out on the inside. It was a bad make.

 

cause that makes too much sense

OP, those gaskets megan gives are ****. use some of the copper sealant on it with new, quality gaskets
