Hey Z1. ETA on those headers?

Voice59

Ive been reading here and there, and what I can gather is that unless I get LTH's I shouldn't even bother getting headers. Unless, Z1 comes out with a set of shorty ones? Then I can throw some HFC's on it and I'm good?

You cannot have shorty headers and LTH.

LTH = Long tube headers. Aka headers that are longer. Short = shorter.

LTH will bolt onto the part most consider a "catback exhaust"

With shorty headers you will need HFC or test pipes.

These headers from z1 are not LTH but so far they seem to be the best option out there for making power.

install for LTH and these are about the same except for some say that getting the longer headers up in there to bolt takes a lil more effort.

Uhh...that's what I said.

Z1 has already released "their" shorty headers. The only thing is you have to buy HFC's or test pipes for an 03-06 350z or better known as the DE motor. These headers are exact copies of the momentum headers originally made for the 350z. These have already proven gains as good as LTH's but no proof that they outperform them as no one has done a full comparison. Hell, for the labor it takes to put em in, no one ever wants to do it more then once lol.

Oh ok. So those headers they've released can fit both the 350 AND the 370? For what I've read it looked like because it was an exact replica, some other modification was required to have it match up to the 370.

PLEASE correct me if I'm wrong. I'm looking at just keeping my car NA for now.

Voice59

I just went back and re-read it. As long as I buy a HFC for the 350 it will match up to the headers. However, will it also match up to my MXP catback?

Lol, definitely a lot of truth to that. It's easy if you have the front of the car completely disassembled though.

You need HFC from the DE (03-06) 350Z engine.

Nice. It looks like on the website they offer their own set of HFC's. I may just do that. Seems like a sure thing.

chrischhorn

The only modification required to make it fit is the is HFC's/Test pipes. Other then that, the exhaust system bolts up perfectly. I had issues at first bolting it up to my exhaust but found out later that it was the TopSpeed test pipes that had bad fitment. Not the headers or exhaust. I swapped them to the Z1 test pipes and sure enough, everything lined up perfect. Found out later from 350z guys that the TopSpeed test pipes had horrible fitment even for them on stock headers and their Catback exhausts.

Thanks man. I'm about to buy both the headers and HFC's right now.

It was also pointed out to me at least that the headers if paired with hfc rather than test pipes would max at 324 hp. So on in my instance is why going test pipes in conjunction.

I can't post the email from Z1 because obviously they have a disclaimer stating you can't repost however that is what I was told. believe it or not.

I'm not trying to discredit you, or Z1. You're both good people.


Just that it seems kind of odd to say that a certain setup is "capped" at a specific HP level, when we all know that there are so many variables that go into play when dynoing that it could read anything the owner would.... or would not, want to see.
