I just want to clarify a couple of things before i call and order the Hotshot headers for the 3.5. Keep in mind i have the 3.0

1) Is it necessary to hook up the EGR to the manifold. I do not want to risk not hooking it up if it will cause any negative affects.

2) New 02 bungs need to be welded on, AC compressor line moved are the only things that need to be changed.

3) In the end do you all think the labor will end up negating the savings of not going with the cattmans for the 3.0

Thanks
Chris

 

Not sure on those Chris, but FYI JWT is having a "sale" on them for $529 shipped, if that's a good price.

dude that is a good price. They only have limited quantities so i guess i got to hurry up

 

1) Not sure about the EGR. Cant you just disconnect it?
2) Why not just get 02 sims like this: http://o2simulator.com/24803.html You have a test pipe so its not like you can just relocate them behind the cat. Or am i missing something?
3) I’m sure you’ll save money, but haven’t there been some inconsistencies with the quality of HS headers? I remember reading something about a “bad batch” or something. As I recall, SR was pissed off about the fitment on some of them. I’ve thought about this a lot and I think the extra 2 bills is worth it to get them straight from cattman. They have a much better rep IMHO. Just my .02

 

I agree about the fact that the cattman having a better rep, but the price difference is about $300 so my thinking is that i get cheap labor to do some welding and i may save at least $200 which can go towards something else. I'm just hoping i don't get one of the duds. I didn't even think of the o2 sims and also i am still not sure about the negative effects of disconnecting the EGR.

 

Yeah I hear you. I still dont understand why you want to weld o2 bungs on there. Wont you just get a CEL anyway since you will have absolute no cats in your car? Or are the o2s upstream of the precats? Cant remember sorry. At any rate, o2 simulators seem like the best way to go.

 

No i agree with using the o2 simulators. I just didn't even think about using them

 

The front O2s are before any cats, so they'll be fine with headers. Rears with no precats or main cat will require O2-simulators to keep from throwing a CEL.

 

now here comes the re-occuring and very aggravating question "Does anyone have any soundclips of the hotshot headers?" . All of the links that i found did not work becuase they are old.

Thanks
Chris

 

Thanks bro, you da man. BTW how do you know so much maximas?

 

The definative EGR thread. http://forums.maxima.org/showthread.php?t=351657 All your answers are present and accounted for. Removing EGR isn't bad and doesn't seem to effect fuel mileage.

 

I read the thread but i didn't see a definitive answer on whether or not removing the EGR raised engine temp and if performance suffered during closed loop ecu operation

 

Really? Hmmm...
Also, this was posted in the "Who's the lightest Max on the org??" thread:
later...
and...
There you have it. EGR is there only for emissions on these cars. The fact that it will hurt fuel mileage is a myth. What it does to CC temps is only postulation at this point but it doesn't matter with an N/A car anyway.

 

They sound good on VQ35s, however the Cattmans' are supposedly "euphoric" on VQ30s. Not sure on the SC's though. You should have StephenMax make you a clip, since he's about as close as you'll get. However, he has an Apexi or something exhaust too.

 

I think the word used was "euphonic", but euphoric is not too far off, especially above 4000 rpm at WOT, heh heh.

Sorry, I don't have any way of making a sound clip at the moment.

My only complaint is that the headers greatly increased drone at 2500-3000 rpm, whereas drone was almost nonexistent with the stock headers. I recently put the cat back on in an attempt to reduce it, but that had very little effect.

 

No postulation about it. That is it's sole purpose. But since it only operates at partial throttle it doesn't do anything to lower the much higher CC temps at WOT.

 

Eh? I wasn't referencing you...another 5th gener who recently put them on.

Anyways, toss that Apexi for a Flowmaster or full Cattman catback. I've never heard an Apexi exhaust that didn't sound bad.

 

I know. I thought he said euphonic, but maybe I misread.

 

Are you saying you can read my PMs?

Here's his PM:

 

Yeah well i am boosted so i kinda have to worry about that stuff.

And yes i saw all of those comments, but i thought i also saw arguments from people who had it disconnected that said it hurt performance

 

damn it, i am going insane here. I want to order these sons a b!tches today but i wan't to make the right choice .

Ice, you know what that $300 saved by buying the hotshot headers is going towards (ATP exhaust cuttout). THis thing is going to sound nucking futts at WOT

 

He said the same thing in a 5th gen forum thread: http://forums.maxima.org/showthread....light=euphoric

Somehow I misread it as euphonic. I guess it made more sense to me that way, but I gotta agree with euphoric as well.

 

Holy sh2t....good memory SM. I never read that thread, just his PM.
