What's up guys?! This may have been talked about to death so feel free to flame. (I couldn't find anything when I searched) I just found out that HKS makes a header for the 350Z. Now I know they have the same enigne as the altima, but I remember hearing the intake and exhaust setups are different. So this header for the 350Z will not fit right? They should bolt up to the exhaust ports though. If the exhaust is different (which I'm ALMOST sure it is) then maybe a really good fabrication shop could make a custom down/race pipe to match up to the headers and stock exhaust? Anyway, the damn headers cost $1800 anyway? Just a thought.
