Heres a nice set of headers.
on a serious note, I hate you becasue you said maybe for life, and where you live your could probably keep it for life, (mine will be a rust bucket before that), then again, unless I turned this thing into a complete beast, I wouldnt want a 240 for life. it would be nice tho to slowly throw few grand a year into it for a while. but anywaywhy get a manifold if your not going to turbo, if you turbo later, then get a turbo manifold, nyway, complete waste of money imo, unless u drop cash it will be mildly slow, just get some worthwhile mods, like suspension or just something other than a manifold.
and btw, wtf do they even make upgrade manifolds for ka, non turbo, and double wtf for downpipe on N/A. I would completely disregaurd this thread but youve been here a year and a half so I figure your not completely stupid or being a fuckhole, please explain. thanks.
