I have 370z Headers on my DE engine. All RWD Headers fit all RWD Engines. If you go with 2007+ Shorty Headers then you need 2007+ Test Pipes.

If you go with replica ebay parts I wouldn't expect them to fit without issues, you will be in for a bad time when they are rubbing your steering shaft on one side, and melting your fuel line on the other.

Honestly it's a hit or miss with replicas, I'm not gonna lie, I run OBX-R 370z headers on my DE as well, even with header wrap, I don't rub my steering rack or touch any lines, there was also no issue with fitment on the motor or where it meets the y pipe.

I paid 330 for them instead of buying 1300 PPEs. Yes PPEs are better quality. But with my boosted setup the difference in gains will be negotiable at best. The merge collecter on the OBX-R headers are the crappiest areas and can be cut and replaced with better ones off Jegs.com or a reputable exhaust shop.

I know that already I'm wondering specifically if the 370z OBX longtubes headers where they made 2 versions the ppe reps and the fast intention reps I wana get the ppe reps but I've heard on one forum here that they hit and won't fit the 350z hr chassis but so I wana know whether either of those would fit my 2007 350z before purchase one

I have the 370 OBX's on my o4 G35 and i dont have any problems with it hitting anything. Worst case scenario you get a hammer and put a dent in the header.

You have the PPE replica i like the obx replica of the 370z fast intentions better because it looks more like the stock setup for space, when in comes to gains i dont really know which would perform better

why would you let go of your longtubes when they make more power then shortys n test pipes? Makes no sense.

Two reasons: First you cant pull the motor with out pulling the transmission if you have long tubes, Second, you can't turbo your car if you have longtubes unless you have some serious fab skills and make your own rear mount.
