Headers?

[Lyle's GTP]

So, it should only cost $700.00 then? 200 Bucks to remove a stud, ouch!....if they paid me that a Optimax I'd be a millionaire. Cheap bastards.

Trust me that 200 was well spent.

You will run into something, it always happens.

I thought u mentioned they where painted not coated...however i could be mistaken....
but ya the quad 4 header was very simple indeed...but alot of stuff you include in your pricing is not the cost of headers but of surcumstances...
And wow 200$ for a stud? Did they lube it before they.... lol

What made the quad 4 difficult was i went with a 3 peice header... sorta like a honda headerI use 1 5/8 primarys on the 2 main peices n the third peice that meets the flange was 2" into a 2 1/2 collector....
All i know if i get gains like i did on my 2.3 DOHC ho i want headers yesterday for my 3.4 dohc...

I have a lot of thigns to consider ...

1 i dont wanna hack the engine bay up...

2 Im not sure if the heat coming off a header is that much hotter than a manifold but if is ...its gonna cook under there on a hot summer day....bein's close to wiring n hoses n such..i dont wanna create a nightmare for the performance thrill.

3 EGR/02 sensor bs.. (that can be if i use them).

He did paint them, he's blowing smoke out his ass again. $200 for coating? I think the decimal point should be moved over two positions.

montessgtp, I don't think you will have to hack up the engine bay. It will be very tough though to get headers in by that tranny. The head coming off a header would be no more than a stock manifold. The only thing that you would have to worry about is how close they get to the other components (whereas stock hugs the motor basically). EGR: simple. Remove it. O2 sensor: simple, drill a hole and weld on a bung!

I'm the one blowing smoke up my ass becuz I actually buitl a set, Dyk just sat back and called bullshit-wait, still calls bullshit.

Anyways it is a "silver" ceramic coating, looks grey in the pic becuz they hadn't really been heated up yet. Now parts are still kinda grey, but about half has gained a shine. A local speed shop did them for me. I wasn't too impressed with the color, but it is a very good coating.

It wasn't hard at all to get the headers above the tranny, beside the motor, and under the Throttle Body. Once the mannies are gone, there is actually quite a bit of room. Shane ran the stock crossover and still had room for a 3" downpipe to run beside it on his turbo MCZ34.

The onyl hacking I did was to the side air box support, a little metal bracket I had to cut. I also needed a new coolant line. The cut subframe was different, that wasn't the engine bay and it could be done without it.

The 02 plugs into the front header downpipe, only reading exahust from the front 3. But it measures percentages, not quantity so it's ok. My EGR is gone and blocked off.

btw Dyk, 200 isn't cheap. A chrome would have been $359, and a silver Jet coating was $412. Add shipping to Kansas for the Jet Coating. But you know everything becuz you've coated so many headers before.

Racer is right, it is a high temp ceramic coating. I don't like the color as much as I do the Jetcoat siler, but the Jetcoats was like 400 bucks.

Is it cermiac paint or a coating... Who coated them cuz i might use them too cuz the place in NJ went out of business. ..200$ for ceramic paint coating is alot ? I use ceramiac paint on my 3.4 dohc manifolds n x-over when i had my engine rebuilt..didnt make any diffrence. Hot jet coating on my 327 headers was 175$ so 400$ is rediculos.

Dyke ,the way i planned on doin is basically making the front header..seperate from the Crossover..basically almost using a idential style setup the manifolds use. but w/a custom x-over and having that one not even touch the other header..but just meet at dual flange. Im not sure what size i should make the x over though bein its 1 solid pipe..n im not even sure how i wanna do the rear yet..ill plan 1 thing at time.

I also dont want the primarys to be much more than a 1 in of each other in length. I dont think a inch is gonna matter to much... considering your working with 20+ inches.. my 327 headers all the primarys are within 1-2 inches in length of the next.

Here's another concern...back pressure? Isnt it that all motor needs atleast some back pressure?

If you think bout it headers + 2 1/2 pipe..is a lot exhaust for a engine...

[montessgtp]

Also aaron to you have more pics of your rear header..only one i see is of that against a concret step. Did you take pics after u had them coated or maybe a complete assembled pic on the ground. I mean damn im gonna take mad pics of this when i do this, so other people can further expertment with my design if they want.

[Anonymous]

I do not yet have pics of the rear(probably becuz I havn't built them right Dyk?), but it is jus becuz I'm too lazy to jack up the car, arrange lighting, and crawl under it all to get a few pics to prove a few ppl wrong. I have headers, good headers, and i knwo it. that is all that matters. I want to help others so we can figure out what measurements gaint he most, but when all ppl do is call bullshit, I start not caring. talk to Pocket rocket, i wrote him a LONG essay on everything I did and what he shoudl and should nto do.

[grandprixgtp_91]

im gonna be making headers really soon, i will post all kinds of pics, i dont really care about gains (although they are very nice and i hear quite high with headers) i really just want my car to sound awesome, i want it to be a real head turner. my car is getting completly modded over. hopefully i will have everything done by the end of summer , but you guys know how things go and how tight money is. so we will see, i take lots of pictures as i go, i am actually gonna put them all on cd when im done and give them away to people on this site if they want them.

If you want your car to sound cool, headers aren't the way to go. The exhaust note is much louder, and a lot less refined than with cast manifolds and a decent exhaust. The power is good, but I think you will be disappointed if your main goal is awesome sound.

Rarer is right, the headers amde it a bit louder, but there is a bad rasp from 1.5-3000 rpm, but after that it sounds great. Unfortuantely that range is where most of my driving was. If you are going for sound, defiantely steer clear of the headers.

hey montessgtp, if you ever get some peeps together for the project, PM me. I cant weld but Ide be very interested in seeing the process and product

So... Let's see 'em!

Sorry for the delay but Just foud it 2 days ago.

Yes, you would remove the AIR pump.

I didn't remove my air pump, I just removed the pipes that plugged into the manifolds and left the rubber line open. No problems so far, no SES lgiht or anything.

Those look good, not equal length, but if you are just doing them becuz the manis won't work, than there isn't anything wrong with them. Plus I bet there is a space issue as well.

[dykz34]

The AIR pump won't throw any codes no matter what you do to it.

You could just unplug the harness to it to make sure that it isn't trying to cycle...
