about to purchase headers for my z, Im now thinking the borla ones, how its this compare to the nismo, 350evo or others?

 

Borla's are cheepest but show the least amount of gains of all the headers...

So far I like the NISMO's best...

XERD's are cool but completely get rid of the cats and no option for high flow cats...

 

For the amount of time it takes to install headers, you might as well go with a more expensive header that has worthwile gains like the Crawford headers. The Borla headers only gain 1HP and that's from David Borla himself.

 

how much gain do the nismo get?

 

I don't think the Nismo headers do much either, one of the racing guys on this forum is selling his because of the low gains.

 

According to Nissan.... 13hp and 13ft lb's max torque.

 

You want headers - buy Crawfords.

NISMOs are great quality - but weren't thought out when it came to MAXIMUM performance. They were throw-togethers that were made to fit, flow better than stock, and get into the market rapidly.

The Crawfords on the otherhand have over a year of development - and the difference of gains are HUGE!

You tell me when ones look like they flow better?

NISMO - Solid construction - shorty pipes.


CRAWFORD - Nice long equal tubes - Smooth Bends


Go talk to ANYONE that is big into headers - they will tell you TWO THINGS. Longer IS BETTER - but there are such things as too long. You won't lose HP getting too long, but you will stop making torque. Per the XERDs - Nice HP gain, no torque!

Crawfords has the balance of both worlds. HUGE gains in HP up top... MASSIVE gains of torque downlow!

If you do headers, do them right the first time.

I got Crawford headers, I got to say they are sweet. They look so good I didn't even want to put them on my car

 

We use Xerd headers on ur 350Z in the Grand AM Cup series.

 

You also forgot to mention you're chopping them up to see if you can make any more torque!

Good luck this year btw.

 

Why are you Crawford guys so aggressive with sales? As Arnold would say "Chill out!!"

 

Another header option coming soon.

While walking through Stillen's shop with Steve Millen last Thursday he pointed out an interesting set of mandrel bent "shorty" headers for the 350Z/G35. Steve said they make excellent torque as well as horsepower. He wouldn't provide numbers as the commercial version has not been dynoed. The headers will be available in ceramic coated carbon steel and stainless. Rumor has it that the ceramic version will be around $800 and the stainless will run near $1000.

That's all I know right now. For more info I suggest e-mailing or calling Adam@Stillen.com or 1.800.711.4126 x-138 or your sales guy. (For those who don't have a sales guy, the first one you talk to is yours forever - PM me for more info)

The set in the car is EXACTLY as it came from XERD.
Thanks its going to be very tough this year.....a lot tougher than last year. But we have a full season of development under our belts and new engine mang system to boot.......Techno Square will still be on board with the team and its great to have them!..........................Oh yeah and...I am always looking for more......after all with any driver....its never enough!

 

Yeah, I agree. It seems like you mention headers and someone from Dougs group starts making comments.

 

Hey BJ, LOVE THE PICTURE!!!!

 

He's not a Crawford representative. Reps have colored titles under their username.

 

I believe the Stillen headers are going to be long tube style replacing the cats a la XERD.

 

Are anyones headers ever going to be CARB approved or are they all "off-road" only?

 

AFAIK all of them are for "off road" use only.

 

Why is it when I pick on friends I talk to on a near daily basis - people take it wrong and start to whine.

If you have a prob, PM me.
