Headers
 

So I found a good deal on Stillen headers but they are for 350z hr but so was wondering if the headers from the hr motors bolt up to ours. And if I do get these what's your opinion on stillens to can't resonated to from cnt to the shorties

The HR headers (370 and 350) are interchangeable without anything else being changed. The DE headers are also interchangeable but require you to use cats from the DE to bolt up. The stillen headers are basically a prettier OEM header. Not really much performance gain if any. If going with shorties, the only header worth while is the Momentum headers from the 350z DE motor that Z1 is planning on replicating for the HR motors that will be released in May. Otherwise, longtube headers.
