whoa. never even seen those before. new? or have i been out of the loop.

 

fairly new. There are a few sets out there. On our website we didn't give specifics....The reason for that price is to sponsor 12 cars at that price. We listed it for a month expecting at least 12cars to take advantage of a normal list price of $760 for the set.

Not only did we get special permission from Charles Westrup to lower our prices during this promotion..but he went one step further and is offering up a $100 rebate.

 

Honestly, they all look the same to me... Strup, top speed, dc sport, megan racing, etc... all look like freaking carbon copies. I'd really like to know what justifies double or tripple the price. All same material, all same gauge pipes, all tig, cnc and mandrel bent.

Where are the Strup headers made out of curiosity? China by any chance?

Unless someone shows me substantial difference. To me it's all CRAP

 

I'll try to get specifics for you on the strup pieces...but if this means anything... Charles Westrup was DC's GM for i believe 25years before creating Strup going off on his own. When he had these produced...he had them done to his specifications.

Man, those look sweet. Any independent dyno results? Does any member here have them with impressions?

 

yeah, foreal, its all about dynos. Nexus has a whole bunch coming. Crawford has 3? DC's got some too. its all about numbers. Pricing doesnt really mean squat unless there are gains.... ie. borla.

 

i posted a chart that was done by a customer..but i'll try to get more info from other current owners. thats gonna take a bit of searching. This car has them.

so does this one

if at all posible...i do suggest taking advantage of this great offer

 

How much is header installation on the Z/G's? (roughly) Never found out before.

 

$400-$600 depending on the hourly rate the shop charges.

 

If a shop is qualified and has done the install before...bottom line with good instructions it should be just over 3 hours...no more than 4. If it takes longer they have not done enough of these installs. Problem is that if you dont live in an area with a place like this it may take an extra hour or two. Best thing to do is start a thread on the best installers in different areas so we can put together a good database of experienced installers.

agreed.

with something like this which is a bolt on...i always recommend doing it yourself if at all possible. Puts you in touch with the car and gets you wrenching. Need to start somewhere right? You'll be proud of yourself as well and you'll start considering more difficult tasks

 

franly the numbers are meaningless too, unless there are are more details posted about the cams, exhaust used, etc etc - otherwise its comparing apples to who knows what

 

I've heard from a friend in the aftermarket parts industry that all headers are made in china and that big companies just slap on their badge claiming it's theirs. That's why they all look the same because they are molded from the same stock. Just my .02.

 

I'm only an electronics guy so forgive the stupid question.

I don't get it. Why would Nissan put headers on the car that are more restrictive than what could be put on? It seems to me that it would not cost much (or any) more to manufacture a header with less restriction.

There must be some design comprimise that they decided on that we are changing by installing less restrictive headers. I dought if it's cost. Is it just too hard to install the larger headers in production? Are they purposly supporting the aftermarket to promote a fan base?

NISMO headers sound insane at 5k rpm--there is no sound like it. Drivers in convertibles turn head when roaring by...rich, san jose, ca

 

subscribing--very interesting

this is true of the knock off headers yes, but not the original designs....

Why don't they use the header as part of the car? Same reason they didn't give us a factory Greddy twin turbo kit, or even NISMO wheels as stock

 

Any real gearhead knows that longtube headers like the Sprints shown above, are the only headers that make real useable power and elevate the entire power curve. NASCAR, F1, and dragsters use LTs, not shorties. Topspeed, Stillen, Crawford, etc all are shorty header designs and aren't worth the money, time, and effort for the meager powergains (10whp). LTs have primary lengths well in excess of 30" and usually closer to 36-40". Install shorty headers on a Ford mod 4.6 or a GM LT1/LS1 and watch the car gain 5-7whp. Install LTs and the gains are 25-30whp. I installed LTs on my friend's 00 LS1 Z28 A4. It gained 29whp and went from 13.5s@103mph to 13.1@107mph. A VQ35 with LTs easily stands to gain a solid 20whp and probably closer to 25whp.

The FM VQ35s already has decent flowing manifolds. Yeah, they're ugly and appear restrictive, which they really aren't. This is easily proven by the small performance gains the shorty headers give over the cast manifolds. Sure, some of these headers see 10-12whp peak gains, but often the average powerband gain is closer to 5-6whp. That's nothing and may result in a fractionally quicker car. A set of LTs will give an average powerband gain of ~20whp. That will result in big improvement in driveability, power delivery, lower ETs, and faster traps. If you guys understood the concepts of exhaust velocity, you wouldn't be putting so much faith into these 20-24" primary shorty headers. Way too many people buy into advertizing.

 

does anyone make longtube headres for the Z/G's? I thought crawford were longtube how about the Xerds?

 

i think the longtube design he was refering to is a design that 2 in 1 (header+test pipe).
