Cattman Headers on a 2k-2k1

Cattman Headers on a 2k-2k1
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.

Gains in which end exactly?

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 $$ .

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.

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.
