that sounds great! Theres a local 1/4 event on the 9th of January and I kinda want to get one before then if they are available.

 

Hey ordered my manual y-pipe some time ago and I still haven't received it yet. Can I still get the group deal price?

 

nope sorry your screwed.......haha just kidding, we can take care of you, just call us when the group deal starts and we can switch you over.

I am assuming the Y-pipe is in place of a catback system?

I guess it wouldn't be possible to put the Y-pipe and the Greddy catback.

Question is...Which is better? Greddy catback or Y-pipe with stock attachment?

 

a catback and a y pipe are 2 totally different parts of the exhaust system. You can have both if you want em. I have the greddy and I may be purchasing the y pipe in the future unless a full set of headers comes out.

 

is there any droning inside the car?

 

No not at all, at least i have not experienced any.

 

Does it make sense to get the Y-pipe and not the Greddy catback? Isn't it pushing air from a big pipe to a small pipe with the same stock mufflers?? Can't be much of a change. The air is going through the same end pipes.

any thoughts??

 

I have no clue what your talking about. The greddy is an aftermarket catback that includes the muffler and piping back to the cat. The cat is integrated into the stock y pipe. If you get the aftermarket y pipe you will eliminate the cat but you will still be running through the stock exhaust system which could be restrictive. Hasnt really been dyno tested so its hard to know how well the stock exhaust performs.

 

Will removing the cat, by installing the new Y pipe, affect the 02 sensors or anything like that?

 

No. The y-pipe has a fitting for the oxygen sensor.

 

Well someone was thinking when they designed it.

 

 

that is exactly what I was referring to.

 

Custom Enterprise: Is there a y-pipe that has a high performance cat built in? If not, are there plans to build one?

 

Does it make sense to get a bigger y-pipe but keep the same stock cat and cat-back system? Isn't the flow still restricted going from y-pipe to the smaller stock cat? This has hesitated me from purchasing parts of an exhaust system.

 

The factory Y-Pipe has a very restricted kink in it. So by changging only the y-pipe you still get a gain.

 

There still seems to be some confusion on what the y-pipe does. The y-pipe eliminates the main (large) cat in the stock system. There are still two small pre-cats left, one in each of the stock exhaust manifolds.

By adding the y-pipe, you would still realise some performance gain, but you would still be pushing the exhaust through the stock resonator and mufflers. The addition of an aftermarket "cat-back" system to the y-pipe would undoubtably open things up and give you a few more ponies.

 

How did the pipe feel 04redmax? I figured the HP gains they showed were real but wasnt sure about the TQ. Ive got a lot of the same mods you have and I was just wandering how it compared to the other mods.

 

It's amazing what something so simple like a y-pipe will do for hp......

 

I am puzzled why there isnt a high performance cat welded on the y pipe so that it remains smog legal AND yileds more ponies AND is good for environment. A glance at the y pipe pictues I have seen shows it would be easy to do.

 

Probably wouldnt gain as much power if it had a cat.

 

Cats like the Random Technology lose very little, if any, power.

 

Well I do know that on the 350z random tech cats arent very good. Theres others out that outperform and outlast them.

Your the man greg!!!

 

No Prob.

 

now i see what the dyno #'s of the CE Y pipe. if you folks wanna check with bryan @ Berk Technology. i dynoed there Intake with Midpipe on my bone stock 04 Max, Dynoed to the wheels 218whp 232Tq Why does the Y Pipe not give any TQ, my max stock gave me 219TQ stock Vs your stock TQ 193?...... Something is wrong with these dyno's. mine was done on a 7 month old Dyno Jet full chassis dyno. accually just calibrated by dynojet

 

Greg: ANy recommendations for an exhaust system after the y-pipe? ALso, any plans to make headers for 04-05 Maxima?

 

DeusExMAxima: there are alot of good cat-back exhausts ou there, we have had good luck with the Cattman, our dual exhaust, and the Greddy. All have shown to work well with our y-pipe. As far as the headers, we have several other applications we will be working on before the 04-05 but they will be developed some day, just can't say when.

-Greg

 

Could you explain more about the gains with the greddy exhaust? Was it much better than stock with the y pipe?

 

Are your cattman and other apps for cat back exhaust for the 04-05?

 

Does adding the Y-Pipe void any warranty from Nissan?

 

I just ordered the y-pipe for my 6 speed 05 Max. The wait is on!!!

 

I can just see in a year, the max kicking up horrible smoke because of the small pre-cats in the Y-pipe getting worn.
Does it even pass inspection?? NY...CA??

 

OK I just got back from installing my Auto Y-pipe. First performance impressions are an very noticable increase in torque and low to mid range power. Very throttle responsive. The install went relatively flawless with a few exceptions. When mounting the aft or rear end of the pipe to the stock exhaust, the original stock Y-pipe has 2 studs and the only thing that gets removed are the two nuts, the studs remain with the stock Y-pipe. This poses a big problem if you are doing this by yourself because you have no way of mounting the new Y-pipes with this hardware. I attempted to remove the studs but that made no difference because there is no threaded section on the aft portion of the stock exhaust or the CE pipe so I would have a nut on one end and nothing holding the other. I sent my wife back to the house to look in the box for missing hardware..none..I called CE and the guy I talked to said he watched the install at a local exhaust shop and they used all stock Hardware. Now I am pretty creative but there is nothing except the stock nuts that you can re-use on the aft portion of the Y-pipe. So I sent my wife for a quick Home Depot run for some new bolts and that fixed the trick..sooo..My only complaints to CE is that you need to buy two additional 11mm x 1.25 bolts approxomately 4'' long AND they didn't include any gaskets for mounting which the CE guy I spoke to said you didn't need any. I re-used the aft gaskets and used one of the forward gaskets but couldn't get the other side off so I am running one without any gasket. After the complete install I did a once over / leak check and everything looked great. Greg was I supposed to get gaskets? All in all the install went fine and the finished product is great.

 

Bigcat: Do you have any other mods to your car, especially exhaust or intake?

 

Yes I have the Injen intake.

 

Would like to hear from the company about the gasket and bolt problems before I place my order.

 

Yes. I'm interested in hearing about that too.

Also is there any theoretical reduction in fuel economy? Other than a tendency to be heavier with your left foot after the install? Opening things up usually results in better fuel economy. Installing an aftermarket intake usually gets better economy, to a very small degree.
