there is so little room at the back end of our engines...which creates a problem.
oh ya you gotta throw in an egr bung which is easy enough but it has to be in the EXACT right spot because the egr tube is a hardline....
also ground clearance is a problem...good luck!

 

this is kinda long so i can't read the whole thing right now. But if you can get them to make this 99 cali emissions compatable and also add some HP i would be down. $600 is an excellent price and i am sure it would be cheaper since there will be more companies selling it.

 

sounds ??!?!?!? sound???? who cares . i want power

 

I disagree hotshot will make money because they will be sold of $600 instead of $825 and be more affordable hence selling more headers and turning a profit.

 

The only way I can imagine a nice equal length setup happening is if its an open header. If it doesn't need to connect to the catback then you could just go straight down and then there would be room. A car with this setup would obviously be a track only car though.

About the EGR; it is such a PITA and makes the IM so dirty. Get rid of it. I did.

 

Maybe I'm confused, but why do people keep saying "make this Cali-spec compatible"? The headers are what attach right to the engine, so they will eliminate any extra pre-cats in the Cali-spec...right? So it shouldn't matter because you have the same engine.

 

It shouldnt matter but I do believe Cali specs had an extra bung hole for the extra 02 sensor... which if they didnt come with it, you could always take it to a shop for them to weld it in.

 

Yes, calispec had an extra o2 sensor.... No biggie though.

 

don't forget the EFR connector...that needs to be added to the 02' headers to make the work with our cars...

 

I see, thanks. Although if you've removed all the precats, the extra O2 is probably totally unnessary and even detrimental since it was designed to be part of the complete system with precats. So ideally you could remove the O2 sensor and replace your ECU with a Fed spec ECU (if there was indeed a difference between Cali and Fed ECUs). That would be more complicated than have a bungh welded, though.

 

i like my egr. not really but if i don't have it then i'll throw a CEL...

 

I didnt think about that, if you could swap FED and CALI ECU's then yes it would actually be very helpful but I doubt it.. if you ever see a 99 Cali spec engine bay, you'll see all the extra emissions crap they have. However, you'd still need the extra 02 for your engine to read the exhaust and tell the ECU if your running rich or not.

The reason I say its easy to just weld bungs is because I bought my Cattman Y pipe off of a fellow orger who was boosted and he had 2 bungs welded in for his boost gauges.. I ended up plugging them but I guess if I ever go boost I have that there. Or if anyone wants to trade their Y pipe + money to me if they need those bungs in it..

 

Cattman Headers are made in New Zeland that's why they cost a bit more, I was about to buy a set when they where 700$ but I miss my chance and now they went up at 825$. I mean if HS can make a good set of headers with similar gain for 600$ or less, count me in I want a set asap, 2k1 Cali spec.

Cheers

Why not just make them with a bung in all of them? Not having the bung would deter some cali spec people from buying them because of the extra hassle and price to have one welded in. If its done to begin with it won't cost any more. This way the cali spec people would be more prone to buying the piece and the fed spec people would only have to spend the $1.89 on a bolt to plug it up. Not to mention they would forever have an easy place to pop in an EGT, wideband, etc...

 

hopefully HS doesn't have the fitment issues with their new design like they are having with the 3.5 maximas. This would be a great deal if they fix all their issues

cattman's price difference is justified when you look at the differences between the two. Hotshot fitment issues: (paper gaskets, SAE bolts on a japanese car, header flanges, flex section, manifold to y-pipe portion)

I don't know if you can "justify" Cattman's $825 premium i think he was making a decent profit at $700 and he is now making an even larger profit at $825 because simply he can sell them for that much.
I Have owned hotshot headers before and their products are excellent quality and fir and finsih were excellent.
I am a lazy person and i live in New England it has been anywhee from 20-32 degrees for the last 5 days. i work 4 hours a week and like to spend my weekends doing what i wanna do. I just wanna buy these headers give them to my mechanic and let it be done. I don't wanna have to have him fab up a new egr tube and weld in O2 bungs.
VQuick i think because we are calispec cars we will need to mobe the 02 sensor that is in the Pre Cat from the front manifold to after the main car under to car otherwise we would have a check engine light from the readings.
Does anyone know who has headers on a 99 with california Emissions

 

so I just got off the phone John...the owner of Hotshot and he told me they are swamped with stuff till the 1st of jan....he did say however, that he is very interested in making these headers and introducing some kind of introductory price for those that are the first to jump on these once they are ready if the demand is as great as I say it is...

on a another note, he also said that he would need a socal maxima that can leave them their car for 3 days to 1 week...(unfortunately the way my work is going and that fact that I just sold my other car I can't offer my car for more than 2 days at any given time)...he also told me that our maximas would recieve a 2nd generation header which he has been meaning to produce but hasn't got around to it...basically, I sent him a pic of the cattman headers and he said he thinks there are a few minor modifications to it's design that would result in more gain that he would like to try when making our headers...

John promised that no headers will be made until they fit perfect and give good gains...

anyone locally with 2 cars....so they could give them their maxima for 3 days to a week in february...??? John also told me the after intro price would be indentical as the 02-03 maxima headers they currently produce...

it was funny when I brought up OBX and stone racing headers for our cars...he just laughed and said how many designs of his they have tried to copy and have done unsuccessfully as they send them over to China...and they screw it up over there...

 

My guess would be that the Cattmans went up because the value of the US dollar is declining. And since these are produced in New Zealand... Just like the Qualfies. We get screwed when the gov puts us more in debt.

VQuick isn't cali spec. You are a victim of the common misconception that all 99's have a pre-cat on the left manifold. This is not true. Don't worry I was a victim of this misconception until we installed his Y-pipe. Throw all this out the window if you deduced from his suggestions that he was cali-spec. About the O2; if the pre-cat is removed it will not throw a code. It can be placed in the stock location. The only time an O2 throws a code is if it reads the same voltage for an extended period of time(Probably >30 seconds.) The only time this will ever happen is if the sensor is totally dead.

 

if you guys can, call John at Hotshot and express your interest in these headers!
(626) 303-0076
so he can really understand how important this project is...

additionally, if you are a california maxima...talk to him about what offering your car for a prototype for 3 days to 1 week would involve...(maybe a set of free or reduced price headers)...

 

that sucks i would love to offer my car but i live in ma and have a 99 with Cali Emissions that sucks. i will call him anyway and express my intrest

 

Well my car is Calispec car and i would like a header designed for my car with the extra bungs. If what your saying about the O2 Sensor not needing the cat then why did cattman tell me i would need to extend the sensors and place them after my main cat under the car?

 

is he looking for only 4th gens, or any 3.0 maxima? Cause mine is 2k1 cali spec, however I do not have EGR

 

I already sent an e-mail saying I'm interested in paying 600$ for a set whenever they're ready to collect the cash.

Cheers

 

I called hotshot and this afternoon and Spoke to John. He is a a very nice guy. Basically what was said is that he believes there will be no problem in Developing a header for the 4th gen Maxima. Once he has Micheal's car in he said there will be no problem making a jig for the headers and everything will fit perfectly as it should because everything will be taken into consideration. The reason they would like to have 12 prepaid orders is so that they know that there is a definate interest in this product which is understandable. He also explained to me that the headers should be about the same price of the 5th gen 3.5 header but the first 12 guys would end up paying more like $500 for the header that is going to fit perfectly.
I am going to send an e-mail to confirm that i will be willing to prepay for a header since it will be only $500 and i know hotshot makes excellent quality products.
Also simple logic would lead me to belive if the cattman headers can be used on 95-01 cars then once hotshot has a prototype header from Micheals car it will be compatiable with all maxima's from 95-99 atleast and minor changes for the 99 Cali Emissions cars.
If there is anyone who is interested in this Excellent deal i sugguest you contact hotshot. Also even better if your a 99 with California Emissions and would like to let them look at your car for header development you could possibly walk away with a full set of headers installed for $500 which is an excellent deal.......
Come on guys don't be cheap, you know you've wanted it now you can have it.
Why spend $200 on a y pipe when you could possibly have full headers for $550?

 

he wants a 4th gen...so he can fab up the egr connection....a 2K or 2K1...he would basically just give you a 02 or 03 maxima header which they already have...

like I said before though....he can't start work on a prototype without a maxima to use and even then he can't start till the beginning of january...but he needs a 4th gen for 3 days to 1 week....the most I could lend my car to him for is 2 days in a row so it wouldn't be possible to use my car...I don't have a second car anymore...

so if anyone feels like getting the headers for $100 off and free labor....by all means...offer your car up if you have another one and you live close to Irwindale...

John seems to really know what he's talking about...he told me his dad owned a company that pretty much made just headers since he was 3 yrs. old and now here he is with his own company...which has been around for a long time as well...!!!

 

Cause Cattman is on crack. The only reason that is there is to make sure the cat is working properly. The signs of a bad cat would be an overly rich exhaust flow. In this situation the cat would not be providing a medium for the last bit of combustion to occur and therefore the flow would be rich. I have a test pipe and I have observed that the rear O2 reads even leaner than before but only slightly. I cannot explain this but it is what I've been reading. Because the difference is minimal between cat and no cat the ECU thinks all is fine. Maybe the fourth O2 on the cali's is very sensative and would throw a code. If so I say just do away with the whole sensor and pop a resistor in a simulator to fool it. Or do what VQuick suggested and swap over to fed spec ECU.

i Live in mass and the do emissions test here. Also i want a header made for my car. I am not going to pay $825 for the Cattman when hotshot would be willing to do it for $500. I want to keep my cat. I don't wanna have to retro fit the 02-03 hotshot header to my 99. Cali emissions is gay

 

i'm not going to comment on cattman since they have the only true header set up and everyone knows it, they can charge an arm and a leg. I'm sure if Hotshot comes out with these the cattman price will go down...

With that said, it sounds like we wont be getting anyone to make true long tube equal lenght headers so you'll be getting something similiar to cattman, less quality and same gains for cheaper... cant say its a bad thing

 

I doubt Hotshot will do the long tube headers and whatever their reason will be i am sure it is justified but atleast you will have another option for a sheaper hedaer than the cattman that does the same thing. Have you ever owned hotshot headers? how can you say they will be less quality? I have owned hotshot hedaers on my S13 240SX and they fit perfect, never rusted and never cracked sounds like good quality to me.

 

Broaner, Cali-spec has more O2 sensors, and the Cattmans are made for non-calispec, which have 2 less O2 sensors.

And this is an old subject where neither header manufactures have shown gains over a y-pipe only in 5.5g country.

 

Nope I havent but I read about sr20's trials and tribulations a long while back... if were going to have the same issues your gonna get what you pay for.

 

you have READ. Key Word READ. i am not saying that a couple guys may not have had problems but did everyone have problems? Then why is it everyone still holds hotshot headers to be the best for the SE-R sentra?
I will take my chances...No one is forcing you to buy it Ant. I know there are 11 other people on here willing to prepay other than myself. Also i have alot of faith in hotshot for the simple fact i have talked to the designer and he seems very Competent.

I am not trying to be rude but why is there always guys on here to have to object to everything. Micheal started this thread to raise intrest, if you interested post what you have to say. If your not just move on you don't have to share your every objection. Also if you guys want long tube headers call hotshot and tell them don't just hop on here and say they are not going to sell any because its not long tube. They will see because they will be cheaper and they will work. they may not be perfect but they will work.

 

They may not show significant gains in Fed Spec 4th gens because iam sure Cali Spec 4th gens like mine may see more performance gains because even though i have the Y pipe i still have the front pre cat.

 

I know cali's have four O2's. I was referring to the one that checks up on the precat. I've never even seen a cali engine bay but logic tells me that there is going to be one O2 before the precat, one after the pre-cat, one on the rear bank and one behind the main cat.

Zack, why would you not be able to keep the stock cat? I was referring to the pre-cat.

 

Zack I'm not bad mouthing them, I think its a great idea that theres competition and cheaper headers. But the point I'm trying to get is if they cost less, dont expect their quality to be up to par. For the price you cant go wrong, honestly by spring if they are in the $500 range I'll probably get them.

 

Cali Spec Engine Bay



non cali spec engine Bay

 

Thanks for clarifying. That is odd that there isn't an O2 to check that the final cat is functioning.

 

I suspect its because they figured the first 3 should take care of everything. When i installed my ypipe i removed 2 but there is one built into the front exhaust manifold and i have the final cat. I suspect that if i can remove this front pre cat with the new manifold from the header i should be able to free up a decent amount of power.

 

Agreed. 1234
