Has any clearance things changed since the 04's have a different front end?

i think the 01-03 ex owners had to shave a portion off of their motor mount? to make a header fit. the auto ppl didnt have to.

but im not too sure about the 04 but it could be possible. my guess is that it'll just be like the 01-03's

If I put a header on my civic would it lower the reliability or anything. i have a friend who says it will start affecting the engine and it will become a pos. any input please!

There shouldnt be any reason that that header will harm your engine.

Just got my Megan header in the mail today, looks very nice and quality. Only cost me 75 bucks on ebay. Before you buy a header, look on ebay for obx and megan ones. Very cheap with just as good quality.
