These are beautiful headers (Much better designed than the ISR long tubes in my opinion). I will be installing these on my g37 as soon as I have the money. Gotta delete that rats nest of a factory oil warmer first though 😂. Suggestions on new o2 sensors btw? I’m gonna go ahead and replace them when I change out the headers. Should I just go OEM or is there an aftermarket brand that is a reliable upgrade? And last thing, will y’all be offering a titanium stud/nut kit? I don’t think the factory ones are titanium.
Thanks and we look forward to working with you. No need to switch from OEM O2 sensors, we've found that the factory work fine. Likewise, we haven't seen a need to move to titanium studs. Thanks.
Possibly. I say that with hesitancy because we've never tried to test fit a set. It's a different chassis than its predecessor G37 Sedan, as you may already know.
Sure, rasp is subjective, as is all sound based on the tuning of our ears. I'd ask first and foremost what is the combination of the full exhaust system? Reason I ask is with 18" resonators within our x pipe and our 14" touring mufflers, I don't think the overall output is raspy at all. As for titanium, we do not offer an option in that variation, and they will promote more rasp over any other material we could offer these up in.
Beautiful pieces but I got to ask, why use mild steel on the flanges as opposed to stainless steel?

Any sound clips?
I can’t find a video nowhere with how they sound. All i come across is FI cat back
Does anyone know if you can still bag your Z if you were to have these FI long tube headers? installe?
When are you guys going to make a fast intentions intake manifold and throttle body upgrades?
Drop dead gorgeous. Wowzers.
Thanks. Glad you like what you see.
Does this fit a G37x sedan? I’ve seen a video but I wasn’t convinced. I can’t find headers for a g37x
We've heard of a few customers installing them on the G37x Sedan.
Good for 370z?
These are great for the 370Z.
@@FastIntentions i realised how dumb of a question it was after the fact sorry. haha
What do you think about fitting these on an HR 350z?
Will be fit on q50 3.7 ?

Will F.I. offer catted long tube headers version?
Too raspy for my liking. You have any titanium ones.
