Hehe, it's a 248c. He floored it too soon at ~ 55-60 and it obviously down shifted to 2nd, and then up into 3rd, and if you have an auto, you know that there's a little blip @ ~ 3800 rpm if you do no shift into O/D (4th). I believe it's the lock-up torque converter.

On my latest run, the one w/o the blip, I told him to start at 70mph instead of 50 to eliminate the abrupt downshift and it worked a lot better and did not show the blip.

The files show differently (no blip) when shown relative to speed or time. Check my cardomain.

 

He shifted from 1st to Reverse, then back to 2nd.

 

Same dyno, but viewed plotted relative to speed, he floored it too soon.

 

$900 for 13hp, ahg!!! The price is definatly the only sticking point keeping me from geting a set.

 

Who said it was 13whp gain?

 

You did:
You weren't talking about the new Cattman headers, but you still said it.

 

once again people worried just about a peak figure. People will pay $500 for an exhaust that might gain them 5whp and hardly anything throughout the curve but when a part comes out that makes more power everywhere throughout the power band than every other bolt on combined you think it sucks and costs too much. I just dont get some this crowds logic.

 

D-love, I know Iw as being a smart as.s.

It's ***** waving syndrome


When the mevi was first introduced people were paying upwards of $600 for 5-8 peak gain. is that? .But its significance lied in the gain of 40 whp at redline ...

 

(VQ30DE) 4th Gen -

where is dave b when you need him ? i just hate to see people toss money away for nothing. a good ypipe is still the best option for price and performance (4th gen).

first generation cattman headers are a better mod to experience than a ypipe, but my best 1/4 mile is still with the ws ypipe. my advice to 4th gen guys with 3.0L is to keep your ypipe or first gen headers, there is no way these will make 10 hp over the better quality first gen 3.0 liter cattman header. My maxima has even crossed from the USA to Japan to NZ by ship and there is not a spot of rust on the headers, anywhere !

 

It won't be more worth it for the 3.5 than the 3.0, since the reason it gives big gains on the VQ35 is the removal of the precats vs removal of precats are done with ypipe on the 3.0. So there wont be a bigger gain for us 3.5-liter guys.

 

so whast the deal on these headers? i want a set for my max.

 

Read post #1 of this thread

 

its to bad we get raped like this those XS headers i bought are 304 ss all the piping for $170-$200 to bad they dont clear our crossmember

 

That statement is funny all by itself. The price means nothing if they don't fit. Hey, I got some headers off a vw rail buggy I will sell you cheap, but they won't clear the firewall on your maxima, killer deal!!! You have to pay for quality.

 

That is what he is saying, the Cattman ones are not the highest quality. Not one complaint about the XS Headers on the Altima forums....

BTW He bought Altima headers to see if they fit.

 

New Zealand !?!?! Dam thats where I'm at, I wonder who makes them here?

 

yep. i'm always lurking in altimas.net and the headers for their vq35 application are WAY cheaper and they are dynoing just as high as people here are, and they're also hitting up the tracks just as well too. autos are in the 240fwhp range and are pulling high thirteens with headers CHEAPER than the hotshots for our own car...sad isn't it

too bad they have like NO suspension products whatsoever. there isn't a single FSTB that works for both motors, they only have one option when it comes to shocks (and they're a ripoff). so i guess it's a tradeof.....but dang i want to be able to pay half the price for headers like the altima guys and still get the same results.
