WHO makes the best header

[Jeff G 78]

The AZC header is the MSA 6-1 header.

Really? I didn't know that. I asked here once before if it was and I was told NO. At least now I know that I can buy the MSA exhaust and it will bolt up to my AZC header.

Thanks for all the great comments. Rebello or Stahl.

My 71 has it orignal 2.4L and E31 head. Everything has been gone thru.

Head and carbs done by DL potter and Block by myself.

SInce i have invested that kind of time effort and money i dont want cheap parts now.

again thanks all

For your info, here in Europe, we've done a group buy: we gave a Nismo header to an exhaust shop in UK. He has worked for many weeks prior to propose to the group a Nismo replica version.

Full exhaust runs 1200€ (1500$), if you're interested you should give a look at zclub.net. shipping though might kill the deal...

I've got a MSA 6-2-1 that is good enough for me, Ive got no complain at all so I'll keep it. so I'm not part of the deal

MSA sells a 6 to 1 header that is thermal coated for $319. I know it gets mixed reviews but the price is right.

I haven't examined the two up close, but just look at them. They look EXACTLY the same. I bought mine from AZC FWIW.

I found this pic here for the MSA, tried to find a pic for the AZC, didn't see it on Dave's site. Maybe he doesn't sell them anymore?

Anyway, my AZC header looks EXACTLY like this (I even welded in an O2 bung) but mine is rusty.

Look at post #11-12

It didn't hit my mind when I've read "Brit". Reading it quite fast, I though it was a first name :stupid:

I'm really surprised that no one has mentioned Clifford Research,

since Clifford are inline 6-cylinder specialists. We've had a Clifford

header and full length dual exhaust system on our '70 since about

1973 and we think it is terrific. Durable, nice looking, performance

increase, nice tone, etc.

One of the reasons we bought the '79 ZX recently, other than the

price, was because it has Clifford products on it including a 4-barrel

conversion on a Clifford intake. Having been pleased with Clifford

products in the past, the Clifford element closed the current deal.

Hi Rick,

It was good talking to you and getting a chance to see your car in person at the Zcon this year. I believe the Clifford header is the same as the Datsun Comp header mentioned by Conedodger in post #2 above. Here is an old thread that discusses them http://www.classiczcars.com/forums/showthread.php?t=32243. I have one myself and I'll probably use it on one of my cars eventually. I don't think they are available new anymore, but they come up on ebay periodically. That's were I found mine.

For performance number (from the testing or test results I've seen) the Stahl gives the biggest performance gain (area under the curve). I have not seen test result for some of the more exotic 6 into 1 headers made in Japan and I haven't seen any test results from Dave jarman's header.
