Hey guys,

I've been asked by an old sponsor to see what the interest may be for a tubular manifold for the Evo. They are looking to fabricate one and have it ready for production very shortly.

Here are the specifics:
4-1 pyramid merge collector
304 Stainless
Ceramic coated
Tig Welded
pricetag between $850-900

Here are a few pics of a manifold they already created for a 4G63 motor.*Note this manifold still had not been ceramic coated.



To give an idea of the finished product- here are a few pictures of a manifold they fabricated for the Mazdaspeed Protege. This is with the ceramic Coating

 

Can it be made out of the 321 stainless or is it 304?

 

lol oops sorry I forgot that detail... It's 321

 

how much?

 

Looks very nice

 

between $850-$900

 

Damn, that is one good lookin manifold. It looks like it is an equal length manifold, I am right?

The price is a little steep but, I guess you pay for what you get.

 

Yes- it will be equal legnth.

 

bump for a great manifold

 

If I don't buy the RnR one, this looks like a good option.

 

bump bump we need more interest!!

 

Thats what it looks like a copy of. RnR should have put a patent on that style.

 

This actually looks interesting to me.. But I just can't afford that kind of money.. You will have to put up some real dyno numbers to prove that an equal length exhaust manifold is a worthwhile expense.

 

Yes, it's all going to depend on real world improvements....HP, TQ and spool-up! Not just someone saying it will increase all of the above.
