AMS Headers
 

Found this. Click on the blank pictures, they'll come up. AMS always makes great products.

AMS 370Z STAINLESS STEEL HEADERS - Intake / Exhaust - 370Z / G37

VQ37 specific competition for the VQ35 Momentum headers?

They claim 14 to the wheels. Isnt that close to what e stillen shortys will gain?

is it just me or does that look kind of like momentum's logo on the blank little pictures ?

nice find OP

meh,,, the Momentum are better
those AMS are pretty much a copy of the stillen , again another shorty headers with crap collector...

Momenton headers

Due to design, material, or what?


Pics of Momentum to compare?

I edited my previous thread.

So basically Mandrel bent tubing vs welded pieces is what we're looking at?

Damn they do look like the Stillens. I guess businesses just want the quick production instead there own personal R&D.

the momentums are better, but there were only 4 or 5 sets made. I think, if they still have one set, that is all that are available for sale. Glad I got a set!

there where way over 5 sets made. I know more than 6 people with these. LOL

just a hint .. look at the collector

I know how the stillen are made since I had a pair of those and they have a very similar type of collector of the OEM headers , which such at scavanging .

those AMS have the same exact type of collector as the stillen shorty, since I havent seen how the primary merge together on the AMS, my opinion stop here but knowing they look pretty much the exact copy of the stillen , I would suggest to look at something else.

the Momenton have way more efficient merging primary in the collector and is also going smothly to the flange to optimize the scavanging.
mandrel bent is also a must but a proprely welded tubbing can do pretty much the same job.

I was referring to what is now available and used on the 370. There were more, but they were always used on the intended engine before.
