noise level must be kept to a minimum...as this is my daily driver( i have another weekend toy) and i just use this car to commute back and forth to work

i havent looked into this but can u buy just the headers w/ no y-pipe from stillen... and if so will the stillen headers fit right with the cattman y-pipe? i dont think it will work from looking at em. let me know if im wrong.

get the y-pipe like i did. $tillen headers LOSE power, so why waste the $$.

Y-pipe, intake and ECu..= good power and cheap! thats what im doing! less than $1000 and looks like good WHP!

FYI stillen claims the 19hp can only be gained if u have stock cat and b-pipe. the reason me and studman lose power is bc we dont have enough backpressure. i would not purchase the headers until more people show results. but if stillen claims are correct then 19whp would be nice.

Back to the topic, how much noise will just the y-pipe make? I want to get in on the group deal before Monday, but before I do I'ld like to know if it's going to be noisy or not.

Getting a relatively quiet exhaust with headers/y-pipe will be one of the hardest things you can do. I would guess only a 2000+ year maxima muffler could accomplish this w/o TOO much restriction.

A lot of people wrap their y-pipe to reduce noise. Might want to consider that.

With stock exhaust, y-pipes sound will be minimal.

You will hear the sound most at WOT

That just doesn't make sense. Back pressure doesn't help anything. Sounds to me like $tillen is trying to buy some time to try and figure the problem out.

How has the car been driving?
Are you going to go back to the stock B & muffler?

We need to hook up with Jay & Dixit and go to the dyno in Woodstock. Having and OBD2 scanner hooked up may help us figure out what is going wrong with your setup. I still think it's a knock sensor/timing, coil or $tillens little black box issue.

back pressure creates your low end torque, without back pressure, your car would pull like a 1.8L automatic Integra(From a stop). Ofcourse then you would gain more HP on top end, meaning keeping your RPM above 3000 at all times during regular driving.

ENOUGH of the backpressure arguments..... no one will win. stillen is really making me mad. saying that a OFF ROAD RACE PIPE is designed for a stock cat and b-pipe..... haha think about it. im not sure what im gonna do. have a few things in mind.

All I'm saying is, for a daily driving car, you have to mod the car so that it finds the balance of HP and Torque.

Well I have a WS B & Flowmaster 50 series with everything stock from the cat forward. You know what Will has. Our plots look like carbon copies until his takes the big dip at 4200.

So much for that theory, his low end TQ is just fine. At 2k he has about 205lbs...

whats the little balck rubber thing that goes around the butterfly valve that goes inside of the intake manifold? sry for the sh!tty description but its the black sealer type thing that goes around the 3 sides of the variabole intake valve inside of the manifold. anyways i took this off yesterday and came to find that the little black sealer thing was hanging down and wasnt sealing the valve actually letting more air in at all times. i fixed it as good as i could but the rubber had been sitting so long that it formed to the way it has been for who knows how long. after fixing the rubber thing (temporarily) the car feels much better than before. i dont understand this car why the hell is this happening. im gettin a new rubber thing on mon. ill post when i get it. iahvent really gotten to open it up completly but when i did floor it the car felt like it was much more in control of the power.

Yes the description is pretty sh!tty, but it was good enough for me to figure out what your talking about. There are two gaskets for the power valve, the one you're talking about is a U shaped round rubber ring that goes around the outer edge of the butterfly housing.

That very well could have been causing your problem. The air leak would throw the ECU off, you'd be running lean -3800 and when the ECU adds fuel +3800 it could hickup just like the dyno shows.

What made you think to look there? That is a good catch, sounds like an assembly error.

ha! i have no clue what made me think to take that off and look there. i was thinking since the valve opens and the power loss is after that point maybe that thing had something to do with it. im ordering a new one tomorrow. Bigdogjonx found the part numbers for both the gaskets. thanks guys! after i put the new gaskets on i will definately post how the car feels. 56k on the car and my plugs show definate signs of being worn but other than that they are good to go!

The 2002+ maximas LOVE backpressure. It creates LOW END torque.

When I had my stock exhaust on there, my car was a little quicker than now. Now I have the 2.5 exhaust. Less low end but MORE top end.

That's only one of thousands of correct analysis for the backpressure myth..
