so im assuming the stock headers are thicker as in width wise? how is it not good exhaust flow? once theres no leaks, and hey if it gains just a little improvement its still worth it for the price

 

He's not talking about the manifolds ... but more of the "y-pipe". See that elbow? Not good for flow ... At least attempt equal length like cattman.

 

i dont think OBX really cares obviously there just in it for the dollar. i would deff choose Cattman any day over these!

 

Look at the Y-pipe it comes with. See the 90 degree bend that connects to the rear bank header? See how that pipe connects at a 'T' with the Y-pipe? Big no no. That will absolutely KILL your flow, for the rear AND the front bank. Not a good design at all.

 

VS


Its pretty obvious which are better and the GEN II cattman headers are better yet!

 

im sorry everyone i made a mistake i do not have obx headers or obx y pipe, i have a mandrel bent stone racing y pipe and stone racing headers


and the stone racing headers arent equal length

the y pipe and headers were 300 dollars total

everything bolted on perfect

the y pipe i bought that about 6 months ago and that took me about an hour and a half to install

and as far as the headers the front one took me 2 hours because i had to pull the radiator out

and the rear header i didnt not install yet im going to do it this weekend

 

 

o ok, sorry i just realise what you guys were talking about. thanks for clearing it up though

 

lol well this completly changes the story then... i had the SMR's once and when took my whole day to install wound up not fitting with the included y pipe!! lol so needless to say got a partial refund ect never looked back.

 

also back then didnt relize there was really no point in getting those but now i see everything o so clear that i need to pick up a set of cattmans

 

so for how bad everyone says the obx stuff is, is the stone racing stuff better?

 

Ryan, those are Cattman Gen 1s in your picture... the Gen 2s have a single pieced "y-pipe" while the Gen 1s have a 2 piece "y-pipe" , ie they came with an additional flange before the flex, as seen in your picture.

 

luxbond dynoed the SR/eBay headers on his 5.5th Gen and got no gains.

well on my 4th gen i noticed a pretty good gain

 

Do you have proof?

 

yo! those headers are hot
i gotsa get me some of them.
Let us know what kinda gains you gettin!!!

 

Maybe the same gains as someone else may have gotten from a Budget or Warpspeed y-pipe but with the added hassle of installing the manifolds.

Btw, no dyno, no care.

 

Does anyone ever?

 

yes puppet i knew that, thats why i said the gen II's are better YET. Meaning comparing the obx vs gen1's obviously cattmans are better and that the gen II cattmans are even better than gen I ;p

-Ryan

 

Cool, just wanted to make sure is all.

Btw, based on the dynos on a 5.5th Gen, we're not sure that the Gen 2s are better just yet.

 

There's no proof joos

 

not yet but there will be even if its not on the vq35, im gonna be getting the gen II's very soon and taking my car to the dyno to see how they rate up vs the y pipe.

 

Post the before and after results, can't wait ...

 

deff! and dont worry this is also going to be tuned with the SAFCII so it will be maxed out

 

Both times(y& headers) or just with the headers?

 

well i was planning on dynoing it how it is with y then adding the safcII and the headers in about a month and going again. Remember the numbers are going to be with catback, frankencar intake with apexi, TS ecu also thinking about putting the stock intake back on for a run or so on both to see what happens

 

You need a vi of some sort

 

well thatd be great but i just sold the MEVI and looking for a cheap 00vi

 

No offense but I was the 2nd prototype for the Stone Racing Headers. You can check around and get my before/after dyno runs.

Now you know.
kthx

 

the stone racing y pipe is the same as the warpspeed y pipe

 

puppetmaster
the proof is in my g timer and there isnt a dyno shop around where around my house

 

Gtech is not as accurate as far as performance is concerend when compared to actual 1/4 mile times, or dynos.

 

im not saying its accurate as far as that im saying there is a decrease in 1/4 mile time on the g timer which inturn means the y pipe and headers did something good for the car

 

I think the point here is that the y-pipe is probably responsible for the improvement .... Not the manifolds.

 

i think the point here is that there is an improvement

 

But it's not worth the price or install pain ..

We (some) maxima people are bargain shoppers ...

 

Thats why we have big awesome group deal forum

 

it was only 300 dollars and it only took less than 5 hours to install everything

 

Well, you did it, and improved your time by a half second according to your g-tech timer. ....

 

Quoted for truth...
The improvement is around 1-2whp at the most and that is stretching it.

I dyno'd before and after install of SR Headers/ypipe...I know better than anyone else exactly what the numbers say, it's my car.



Is it worth the extra $50 you pay 'just' for a ypipe? NO, not unless you are trying to extract every single hp out of the VQ.
