Does anyone have any dyno runs and/or timeslips of a 5th gen 3.0 with Cattman headers. What other exhaust parts are you guys running, and what's your opinions on the sound quality and powerband? What installation issues did you run into? Any info is appreciated.

 

noone has these?

 

I have them, just not on a DEK.

If they can fit the 95 as well as the 03, Im sure the 00-01 iwill be fine since they were originally made for the 3.0.

 

Not really worth the investment, check http://forums.maxima.org/showthread....7&page=2&pp=30

 

You're better off with a y-pipe. ^^

 

I have a Stillen Y as it is, I am going to be tearing down the top end of the motor for port work, and I'm researching cams, but i've found nothing but bad opinions on JWT, which as i find are the only cams available for the 3.0. When the motor is apart I am tossing the idea of doing headers as well, and am looking to see if it will be worth the money mostly, as the labour is all mine, and it'll be apart already. Thanks

 

The gains haven't been proven on a 3.0L

 

The gains are there, I have them on my de-k and more than happy with the gains and the sound is great as well. My friend has a y-pipe, to me it doesn't even compare.

 

Gains in which end exactly?

 

butt dynos and head-on street races do not count.

dyno or drag strip trap speeds are the only true indicators

 

Brian Catts did a comparison between his ypipe and headers on his old 4th gen 3.0. Yes there were gains. There would be even bigger gains on a DE-K.

 

Like I had talked with Blackbird that I have headers waiting to go on (winter here) Spring they will go on. I will be doing a before and after dyno.

 

You should see gain of around 15-20 HP over the Y-pipe, I'll know for shure very soon, since I'll be switching from Y-Pipe to Headers, with FI the gain should be even more and that's why I'm switching to Headers soon because FI is on the way.

Unless someone can provide me with a dyno (besides cattman) or track time, I'm not convinced.

Larrio's right.

And hopefully MyownNismo will prove me wrong, as this will be yet another good power adder for the DEK.

I'm not hating on the headers just want to see proof, like anyone else would before shelling out the $$ .

 

Bad news is if I prove it makes power you'll be paying more since the price is going up. That was stated by cattman in there last GD where I got mine for $700.00.

 

Hopefully the NZ dollar and US dollar will come to close terms to keep the price the same or lower.

I already have them on my 3.5L but for others that want them .

 

my belief that a de-k NA will see gains after the VI is open in the higher rpms after 5k. Anything before that is negligible give or take a few hp/tq

 

I am going to go do a baseline run this coming week as soon as the weather gets nicer, my heavy snow tires will throw off the reading I think. I'm going to be comparing my current Cattman Ypipe to HS headers- I boycotted Cattman 2 months ago. This will be a highly modified DE-K, with no power valve installed, so my low end power aint going to be all that great. I reather have issues with fitting the headers on my car (HS), than spend more and get less. No more Cattman for me.

 

That's why I have my Apex-i RSM setup to activate the VI earlier. I am going do some runs as soon as I get the SAFC tuned. If all else fails add a SC as hnda etr did and made more with the headers.

 

Wow first person I have seen complain about a Cattman product. I have there Catback & Y-Pipe & love it fitment was excellent as well as customer service. Brian was great. If you dont mind me asking what has you soured on Cattman?

 

bro if you don't mind, after you do the install can you send me some directions for the modifications that are needed. I am probably going to buy mine tommorow.

Also why do you say pay more and get less for cattman? Are the hotshots suppose to be of better quality?

 

whoa back the truck on up, you can use the RSM to activate the VI? Please explain because i would love this!

 

I have a problem with spending 900 bux for a product like Cattmans when I can get the same thing for 500 bux, I might need to modiffy the 02 sensors a little bit. I will let you guys know the outcome, I'm going to atleast get a dyno of before n after.

 

The price is high, especially when someone can make them in stainless for a V6 altima (similar headers) for under $180. I'm sure fitment may be a problem at this price though.

Go to all motor section look for my thread on what activiates the power valve. Basically the RSM has a switched RPM output. You can set that to a desired rpm. That output is 12V, the power valve is ground. But a know how to use a relay to switch 12v to ground. Haven't got everything ready yet been kinda lazy. got alot of project and no time. But info is there to help you out. I will post up how to use relay once I find my MECP book.
