i was reading this month honda tunin, and this guy was asking about performance part for the 2006 civic. and they were saying that there will never be a aftermarket header cuz r18 only has a single exhaust port on the head so is that true that there won't be turbo for the 8th gen. civic?

Wassup.....

On you tube I saw this video and I think the sound will speak for itself.
It's a 2006 civic SI turbo, check it out.

I'd be suprised if there was a civic without an aftermarket header availb.

but then again the 8thgen si is running a k20 which does have a "regular" exhaust manifold unlike the R18. when i test drove an 06 ex, i popped the hood to see one exhaust port leaving the block which led me to believe the exhaust manifold was integral to the cylinder head.

looking at the drawing on majestic honda, it actually is integral to the head


and the catalytic converter bolts right up to the exhaust port on the head

so, technically, there won't be an aftermarket header. you can, however, do a port and polish and have a bigger exhaust pipe, removing the cat, and that would kinda do the same stuff

As for the turbo question, i guess you'd be able to use that one exhaust port to have a downpipe-ish connection to a turbo, which would mate to the rest of the exhaust system, and that would make for some fun at finding out where to put the O2 sensors.. lol..

so ur saying that there won't be header for R18? that's kinda shitty......so what do u think about downpipe? is it worth it or not?

and like I mentioned above, its a larger diameter "downpipe" that removes the cat..

so technically, it's not a header, but a downpipe..

damn I should go to bed to alleviate my boredom..
