im thinkin about getting the stillen headers. my question to u guys is, is it worth the close to $1000 for the headers+install?? anybody have them on the HR engine and have any thoughts to share? thanks

 

I think only one guy has them and ive never heard of anybody else with them or even considering them. Really dont see a need for them with this engine seeing as the stock manis are equal length from the start.

 

I do not recommend headers, just because of this specific motor.
I have IMPUL headers and got 5whp with a tune. The HR motor is really picky and doesnt like to get more gains than it already has.
Any header you get, you are not going to get more than 5whp.

Unless your supercharged, then thats a different story. You'll get like 10whp but not on N/A.

So it's not worth it bro. For 5whp i didnt feel a difference. I felt a little towards low end but not enough to really say "wow, thats a big difference"


G37 guys who have headers dont even go over 5whp, so its pointless. All it's going to do is give you headaches because is drones really bad. It'll drive you crazy.

 

Wow Robby, that's probably the most detail explanation I've seen you post.
How you been bro?

Yeah headers are pretty pointless on the HR engine. Save your money and get something else, although there's not much more you can do to your sick **** G.

 

For some serious kick in the pants, swap out the stock headers for turbo manifolds.

 

I though there were no headers from stillen available for our cars!? At least havent seen any on the stillen web-site)

 

huh?? link?? explainn
u gotta call them

 

Running turbo manifolds implies you are running twin turbo's as well

 

Well im not sure about stillen but IMPUL DOES NOT have headers for our cars. Im the first guy ever to put these on my car. These have only been on G37s in japan. Since they thought it was an HR motor it would've been fine.
They were wrong

Im selling my headers though. My friends hommie wants them and he offered me 2,500 for them because of all the extra work put on them. And also how rare it is because it's one of a kind. If someone can beat that price, PM me

 

yeah, i ve emailed them like 1.5 month ago, they told me that they DO NOT have them for the 07+ g35 sedan.

however, if anythin has changed now I would be happy to get ones

 

I don't think Stillen make it yet!!! Ploblem would be the same issue with Steering column.and Yeh!! Our G is not to Mod friendly.As other G member said unless you go with Turbo or SuperCharge unlike EVO and STI i drove both of them from mine friends.It's totally..and i meant totally EVILOOO!!! Just Stock!! faster than mine G already.Imagine with alittle Mod..they're gone!!!

 

THEY HAVE IT. it was on g35parts.com. just call stillen. i spoke with them the other day. i decided not to get them. ughh

 

we know its on there bro, it got a lot of us hyped up.
Stillen thinks it works on the all HR motors but i dont think they have tested them on a 07+ sedan yet.
