DGheaders Performance header: New design tri-y 2.0 2.4 2.6 g63b 4g64 g54b

[thillskier]

IDEA!!
I am installing a new head onto my 95 paired port 2.4 L engine. Can U use he head to make the headers? Or need it installed on a drivable truck?

[camoit]

We need a hole paired port truck to fit around the motor mount and firewall. We have the flanges made just need a truck.

[camoit]

OK so we knock off another year and had many people say they were going to help and some that tried but things were not correct.
But it seems we might have the person for the truck now. It's a 90s something and 2.0 but best off all he lives in Auburn and is a long time customer of M&M Muffler. AKA DG Headers. The member has been on the board for several years just Jurking around. So he decided to take the step and start posting. Well guess what. It looks like this guy is going to do everyone the big favor of letting his truck be used as a model. So a HUGE thanks to Claych for stepping up and getting this project going again. But of course we live in Cali SMOG world so there is no real use for a header out here. So getting a volunteer is hard, because there is ZERO in it for that person.

to Claych. It would be good to pull some numbers off his truck before having the headers fitted and after to gauge the improvement in torque and HP. And I wouldn't say there's 'nothing' in it for the guinea pig trying them out as they will end up with some nice pipes. I would put $600-$1k into the right exhaust system (sounds pricey but when you spend the extra coin the right way you definitely get your moneys worth)

Dyno time real data would be beneficial and probably the best selling point of an aftermarket device like a header, especially on a 4 cylinder motor that deserves more horsepower. If done correctly, it could also help the manufacturer of the header, tune and tweak the header perfectly. Torque, horsepower, rpm, gas mileage, etc, increasing for the best available price can not go wrong.
There is also sensor fittings and gas recirculation fittings to be concerned about for the smog minded buyer. On my restoration T-Bird headers, I installed a special Bosch wideband sensor kit with the an AEM gauge which will determine fuel mixtures precisely for adjustment.

People in the forum need to really get together on something like this and make a purchase as an organized group. Remember that the larger the order, the lower the price can be. Shipping cost would depend on your location. Start saving your money!

I am sure that when the header is close to producing, a thread, will or should be made just for forming a group buy effort.

One last thing I thought of is coatings. I don't know what or if the designer will be offering coatings for the header, for example; Ceramic, Chrome, Plain, but if so...what additional cost might be.

Thanks Claych for the usage of the vehicle, which the forum I'm sure will be grateful to whom purchases one of these headers. By the way, since your loaning your truck for the creation, can I borrow your truck for a while after the header is in place also? lol JK!

Here are a couple examples of Tri-Header designs for those wondering what a Tri-Y header might look like.

Out here in Cali you can't use after market parts without a CARB number. To get one would cost around $500,000 so that's not going to happen. I can't afford that.
This thing is based off the Doug Throughley header. It's a direct copy.
As for coating you can take it to your favorite place and have it done however you like.
We are lucky just to get a place to make them for us.

[claych]

Just My way of sayin THX !!!.

[camoit]

I just got off the phone with Dom and he is going to look into a stock replacement try Y. He is going to try an keep the cost around $300. This should make a good header for everyone that is not wanting to dump a bunch of cash into there truck but still want to get a boost in performance.

[maxdsm]

I would be in for the 300 .00 $ header for the g63b.I also have a head I could donate ?.but it looks like he has the construction down since he's made them before. Also what is the size of the down pipe ??? 2.25in???

sub'd.

[pennyman1]

Noahwins has the pacesetter header I traded him for the 2.0 paired port that replaces the stock exhaust manifold - don't know if he installed it yet

[BradMph]

I wonder if any EVO G63b guys are going to come running for a turbo header when news gets around, among others using engines that will fit into the headers.
If things go good, this builder should be very busy. I like the $300 price and would probably replace my present header for a better one. $$$ already on standby.

[camoit]

There is going to be 2 versions. The high performance high torque long header pipe version. that will be a direct copy of the Thorley header and a stock replacement unit. It will be an improvement on what you have but not the full blown race header. You should get a mild increase in performance with out busting your budget. And you won't need to mod the thing when you get it, like the one that comes from Australia. You can read the problems on here. http://www.mightyram50.net/vbulletin...for-our-Trucks
Now IDK where the second gen has the CAT. First Gens it was part of the manifold so it was removed when a header was put in. Someone post up a pict of the stock header please.

[DroppedMitsu]

stock 2nd gen has cat under the cab like a normal vehicle

[camoit]

It is under way. Should be another week or two and he will send me some finished pictures. Not sure how much it will cost me to have them built. But thats OK the board can pay me back over time. This is why we have Donators. With the combined force of many we can get things done. Perhaps the board should try and Ebay them. I'll post cost and start a thread in the donator section when we get closer.


Look at that nice header plate. We had then built two years ago. I rented a used head and had them built just for the board. There nice and thick. water jetted so there is no distortion. Then after there welded he will hit them with the surface plainer.

[BradMph]

Its been a long time since I had cats on my California 1st gen truck, but didn't they have a recall which added a 2nd cat down stream from exhaust manifold cat? or was the recall to remove the pipe cat and install the exhaust manifold cat? Gawd, that was 28 years ago my truck recall was done...no wonder I can't remember sh*t, lol.

[geezer101]

If the mounting flanges are any indication of the overall build quality these headers are gonna be sweeeeet.

[camoit]

It's looking good so far. What you think?

[ragragtimetime]

great work!

[camoit]

Here is the one of them. Now let's get some orders going. This is the $300 version. He is ready for your orders. You can contact Dom directly at 530-823-2633 Credit cards accepted.

are the pipes equal length, I hoped for something prettier I guess, but they look workable.

Wondering about pulse collisions with unequal lengths/

[maxdsm]

Ragragtime that looks amazing .... I will be ordering one of these soon for the g63b.

[geezer101]

RRTT's headers are old school. They are some beautifully made and finished headers but I doubt you'll be finding a set of those gems in a hurry...I share Brads observations on the new design headers. I would think having #1 exhaust runner being that much longer will force the engine to pull more torque from that cylinder (might make it sound like a WRX - could be a good or bad thing depending on your allegiances )

[claych]

wow, just wow,

looks to me like the chrome purdy header does not have equal length
tubes either (look close now) but hey its chrome !!!... & long tube v/s short tube--- apples and oranges ---.

[camoit]

This is not for our trucks but it sure looks the same. This is a brand new DT shorty.
