Alright guys,

Did some searching tonight and can't get a 100% clear answer on this, so figured I'd ask.

A friend has a brand new set of G37 headers laying around he wants to sell me for a song. I'm really wanting to get them, but am wanting to guarantee they'll fit ahead of time.

In my research, I came across a post that said they'd work, so long as I got G37/370Z catalytic converters as well.

My question is, will these fit up to the exhaust and all, so long as I use the 370Z/G37 cats as well? I have a Skunk2 exhaust on the car, and do not want to hack it up to make these work.

Thanks for your help in advance!

yes. the difference lies in the header/cat flange. the cat/ypipe flange is the same, which is why the hr/3.7 y pipe can be swapped into a 1st gen g

 

So, this will work then? I couldn't really understand the last part of your post. Thanks!

my bad, i didnt finish the thought, edited.

 

This will work as long as you use the HR or VHR cats along with the header. And I think you have to switch one bolt\stud to on the header.

 

yeah...you have to swap the middle two studs on the head to make them work. i actually just picked up a set myself, w/stock cats
