Nismo headers are about $115.00 cheaper than Crawford which one you will pick and why? Which one will give more HP? please help me choose. Thanks

 

Crawford all the way.

I have heard from one guy that replaced his NIsmos with crawfords, and gained like...10WHP

So Id have to say crawfords! However, the nismos are cheaper, cheap enough almost to get headers and intake...

I'd check the classifieds for better deals. Stillen headers are nice as well.

hope that helps bucko

 

If you're gonna spend that much, you might as well go for the Crawfords. They've been regarded as the best headers available.

 

Had Nismo and switched to Crawfords! Increased torque around the 3000 rpm range 40 ft/lbs !

 

Thanks for reply, Im gonna go with Crawford. Maybe i will get the Crawford Package

One thing im a little confuse about the core u have to send back to Crawford what is that all about?

Again thanks everyones for their inputs, this site has been very helpfull and friendly

 

You have to send them your stock intake plenum. The Crawford plenum is a reworked stock plenum, and they need your stock plenum to make more.

 

but you dont have to send them your headers of course...

 

Stock intake plenum you mean the part on top of the engine? I have to remove that parts myself? Oh forget about it, to hard for me

I lives in Canada its gonna be too difficult to send the plenum. (I wish i lives in Cali)
Maybe i will call crawfords tomorrow and see what they can do for me.
