I just found out that Cobb Tuning is currently working on some Cobb Headers for our GC8's. Awesome! I think it's ok for me to post this, because I was told by Cobb Tuning themselves. Anyways, they said that the headers (if going into production) will be equal length headers. Also, a header-catback (one-piece?) will be available for around $800-900 bucks. It will be a bolt on with a high flow cat.

I'm interested in what they're gonna offer, so I'm waiting until that/those comes out around the expected April-June time. So if you're gonna shell out some bones for a Borla header, just wait to see if the products are gonna prosper. Peace!

That would be kinda cool. Wish I had the money to really consider something like that though.

Did they say where the headers would "end"? What I mean is are they more like the MRT headers or the Borlas?

Sorry, I didn't remember to ask. He said "Header-cat", but I shoulda asked. Also, I didn't ask if it were gonna be coated, stainless steel, or titanium. We'll have to see what comes up or if someone calls them up. :run:

Since Cobb dealed with Borla on the headers, I think their new product will be just as good or even better quality with equal lengths. I'm positive 'equal lengths' are the best type of headers to put out the most HP.

Cool, more header choices. Can't wait to see what they look like, how they perform, and how much they will cost.

"Yes..." I hope that's good enough for ya. IMO, if it were to be an equal length header, it might look kinda like intestines fighting to get to the rectum if you'd ask me. :lol: You can picture it in your mind if you desire. It might look similar to Brullen's Equal Length headers for the WRX, I don't know.

kickin,

Yes, we're currently testing different dimensions to validate the original calculations made on the header. It will be a header/high flow cat combo, but not like some of the others that are out there. It will bolt to a stock cat back exhaust, but an aftermarket exhaust is recommended.

We are also looking into different materials available. Titanium or Inconel would be very expensive. There are a lot of factors involved in determining which material we will use. In order for us to make the most power possible, there are some critical shapes required. Some materials are easier to form than others. We will have a technical article coming up that helps explain more of the details that go into engineering a header.

Some of the initial decisions made on this header were to increase the average torque and not achieve a peaky number. Our cars are tons of fun, and part of that is how much torque we have across the engine's rev range. We have to be careful in making sure that we don't lose low end power in an effort to gain top end. Other makes cover those bases pretty good already.

Andrew: It will most likely not allow an up-pipe to bolt onto it. Headers designed for a NA car will be completely different than a turbo car. There is an extra dimension added to a turbo header which results in just about everything being different.

Let me know what you guys think/want. All input is valuable in providing the best product for everyone.


Cheers,

Poppa,

This is definitely something we want to happen as much as you do. We have a prototype running on a MY99 for roughly 20k miles on the original MAF. Reliability isn't the issue. The issue is being able to supply the demand. Currently, we are unable to keep the speed density based intakes in stock for just MY00 and up cars. We are trying to address this issue to help satisfy the demand.

Does this happen to be DanzBorin? Is the intake going to be similar if not the same to what he is running? I can’t wait until the headers and cat combo are done rough ETA? And according to the dates anyone want to buy a borla header random tech combo?:D

Poppa,

The kit we have is running on one of the shop cars so we can monitor any trouble that occurs. Although, like you said it isn't too hard to get the MAP based intakes to work on a MY99.

The headers will be released before the begining of the 3rd quarter of this year (based from a calendrical vs. fiscal view). Hopefully we'll have a bit more concrete of a release date that we can pass on early/mid April.

Do you have any suggestions/requests for this product?

For example, one of the items we are leaning towards adding into the kit is an electronic "fix" for the O2 sensor to alleviate any CELs regarding cat inefficiency.


Kind Regards,


Ethan Fisher

Note: Edit to explain release date a bit better.

Wishtlists

a) optional EGT/O2 bung ready on the 3rd cylinder
b) Ceramic or some sort of heat-retention coating!

If this product is up to Cobb's usual high-standard, be sure to put me on the list.

I'd like to make a wish list since my Borla's are not in the best shape right now. I smacked a large piece of wood on the highway and they ripped open where the small piece of reinforcement was welded. UGH!

1. Stainless Steel - as large a guage of steel as the Borla's or better.

2. An option for ceramic coating of some sort.

3. Gotta go with that bung on the #3 Cyl. That would be great.

4. Keep it under $500.00 - header only or $800.00 for header/cat combo.

5. I don't know if this is a problem but what about optionally offering some sort of locking header bolts for those who would be using them under heavy abuse.

And that's all I can think of. I'm definitely looking forward to seeing what you guys come up with.

spshutlz and wistful,

Thanks for the input. We will look into the 3rd cylinder O2 sensor bung. The price that you mentioned is what we have in mind. The locking nuts/bolts are another item we will investigate. What do you think about a header protector plate, similar to a differential guard/protector? This would be optional most likely though as not everybody else would want it.

We are looking into a "heat retention" coating. Actually, what the majority of the coatings are that you buy are oxidation inhibitor coatings (stop rust). We want to make sure the header lasts as long as possible. By the way, the really good heat retention coatings do nothing to inhibit oxidation (rust) and will add about $250 to the cost of it. They are a modified zirconia base material and not a ceramic/aluminum metal matrix which is normally sold. This is keeping me up late at night, trying to figure out how much of these items we can include and still keep the cost reasonable. Heck, I thought marriage was tough!

To be honest with you, it is extremely difficult to work with stainless and titanium to achieve the shapes required to produce an acceptable level of power and still keep the cost down to what everybody will accept. When you look at some of the other designs that have been executed and sold, it becomes obvious that the engineering goals were to get a bit of power and make sure they offered all of the hyped up features that would sell the header. I'll try to get the header article up this week to better explain our stance on the issues we have to confront.

Our goals currently are to get you the largest power gain, make sure you have a header that won't rust out on you or break and make sure you won't have a CEL a few miles down the road.


Cheers,

Ok, now we're getting somewhere. :flame: I'm sure there are quite a few of us still wanting headers, but just waiting for the best-bang-for-the-buck ones to come out.

There is this coating place that coats anything heat related that I'm looking into. It keeps the temps down, works 5 times better than ceramic in salt conditions, and has an attractive, shiny aluminum look to it. http://www.jet-hot.com/

Keep us updated, Ethan!

Wow Ethan! :cool: Thanks for the fast response.

Understandable about the Stainless Steel issue. Even an aluminzed pipe with a nice Jet-Hot type coating would be good. Just gotta stand up to that salt and Magnesium-Chromate (???).


The header protector plate would be a great idea. I trashed my Borlas in a second. If I had some sort of protection I'd still be running them. :( I think most of the skid plates on the market (and I said most not all) won't fit over the Borlas. They just seem to hang a bit low. If running a protector plate will we need to install the STi Motor and tranny mounts to keep the engine still enough so as not to smack into the plate?

And for those of us who might be running a Super Charger by the end of the year, these will really be useful. Don't have to worry about uppipes and what nots.

Also, you guys should sell pre-made Torque converter upgrades for the 4EAT's. ;)
