I have a 2k4 auto coupe. I have a Crawford cast plenum, Z-tube, K&N drop in filter and Borla exaust. Now I want to install some headers. Who makes the best headers and do I really need to buy high flow cats?

 

From what I've read, I would have to side with Crawford hearders.. but I'm not liking all the labor that's involved for the installation.

 

They may not be the best on the market, but consider Strup headers if you're looking for exceptional quality and fit. Great performance delivery for your money at a much more affordable cost than some others out there. They come with a 2 year warranty and you could install them yourself if you were so motivated.

Here's a link to more info in the Vendor's Classifieds where we have them on sale, along with an independently submitted dyno chart of before and after install on a 350Z, with nothing more than a pop charger on it. Stock everything else.

Feel free to PM me if you have any questions.

 

I'm waiting for headers that install themselves. I'd pay $3,000 for those!!!!

 

heh, me too! I'm running out of bandaids and neosporin...

 

crawford or nismo

 

+1 for crawford

I'm selling my alphawerks in Jet Hot 2000 coating. These headers are great! I wasn't going to mod my car...but after installing these headers...it inspired me to boost (turbo) so I no longer need my headers.

They go for 675 new and the Jet Hot 2000 (heat coating) is about $240.

Only used mine for about 2 weeks (300 miles) *like new*
Will sell for 700 + shipping.

 

I think that says it all. Save your header $$$$ and put it towards a good FI setup. HP/$ is far superior.

 

If you want the best, go with Crawford. Yes they are more expensive to install, but for a good reason - being larger they take a lot more work to install.

 

I don't know how people can keep recommending Crawford headres.......for their cost plus the fact the engine has to be lifted off its mounts......*shakes head*

 

Does anyone make headers that fit the 05 G35x?

 

I'm with you on this one. It makes no since too me that so many people keep recommending them when they don't even know how much whp they make. I'm seen many dyno's of G's with the Crawford package (plenum, headers, and cats), but none with just the headers. Now, I went with Alphawerks headers which should be delivered this Friday and from other people's dyno deliver between 17-21whp. Hopefully they'll do the same for me. Anyway just my 2 cents. Peace.

 

you already have crawford plenum - get crawford headers and cats - for a full crawford performance package. the only down side to crawford headers is the price + the price of the install (you have to lift the engine a little to get the headers in there).
