Big thread on the 4-1 Ractive, possible group buy too, just search it out BUt 4-1:wtf:

what's wrong with a 4-1 header? won't the velocity of the exhaust gases be greater if all chambers emptied out to one point? or would it be better to go from 4-2-1 in order to decrease that turbulence that these gases create?

 

[markmurray77]

You still gotta buy a mid pipe and then the cat back, instead of just a catback

So what are the header options?

 

[markmurray77]

I think OBX, Racing MAzda, for the 4-2-1, Ractive makes a long 4-1 and essentialpseed makes an equal length 4-1. I know thers a few more though

Hey all..Selling my Header!!

CHas

 

[blackp5ca]

The Ractive Header is a direct bolt on to the factory mid pipe containing the second cat. It is a 4-1. You can buy the mil eliminator for $21 from apexi and not worry about the second o2 and not have to do ANY mods at ALL!! Or..like myself, you can have a muffler shop weld in a second o2 bung behind the second cat ($10) and lengthen your second o2 sensor a couple of feet. No check engine light, and both o2's working as per factory.
4-1 headers are better for low end power, 4-2-1 headers are better for high end power...(I think, thats how it works on sport bikes so I assume the same for cars?...please correct me if Im wrong)
Header cost is $290 cdn...(+tx) Hope that helps.

ractive is going to release a cat back system to accomadate the 02 and match up witht the header. it will be available around december according to ractive. i am putting together a group buy on the headers on the other thread

Hey guys, thanks for your help. I ran across this:

Apexi N1 NA

and

Apexi N1 Turbo

Each for only $160 BIN. This seems too good to be true, considering the prices I've seen for this in catalogs. Are these the same mufflers, and which would be best for a Protege? Thanks.

you would need the na one. the turbo one probably has to big an opening on the inlet side
