at a bolt-on crossroads...

370zDR

I'm in the same boat as the OP, already have Art Pipes, F.I cbe, G3's, pulleys, Uprev tune and still looking for more power while staying NA...

Looking very much foward to your results, I've been in the fence of getting these headers to replace my art pipes, and stilll not sure if they are worth the cost for the gains expected.

How does it work with momentum headers??? are these direct bolt on?

An about gears, has anyone done this on the 7AT?

Yes they are a direct bolt on. just have to buy 350z test pipes to work. I already feel and have seen these are better than LTH. But only take it for what it's worth.

Yea, he will be at higher rpms when cruising at highway speeds. Personally, I don't mind it because I don't really care about MPG.

I'm currently in the process of having it done on my car right now. I have a 7AT and SpecialtyZ will be installing them on December 6th. I will make a new thread with video comparison of the RPMs at different speeds with stock and 4.08s. For the 7AT, you will lose cruise control and you need the differential housing from a 6MT for the gear swap.

is it a major difference in MPG?
and would a 6spd manual loose cruise as well?

dthem370

I would say like a 2-3 mpg difference from what I have read. 6MT will not lose cruise control but I heard that SRM will turn off after exceeding around 120MPH, but after turning the car off and back on, the SRM works again. This is just information I have read from doing research on the gears.

Great people to deal with at SpecialtyZ. Sebs did my car's tuning.

Do You also have to loose SRM on the 7AT?

In my case I'm more of a track junkie, love going to track days and autocross almost every other weekend, so nitrous is not going to work it for me.

Seb did the tuning on my car as well. Awesome guy! That's why I took my car back to him for the gears.

You don't lose down shift rev matching on the 7AT. However, I read it is off by a little. Same goes for the manuals. One member stated it was off by around 300 rpms (6MT) and that it wasn't even that noticeable.
