Tomei headers + overpipe coming!
 

Seperated from the Tomei cat-back thread..

They released their cat-back exhausts last night, and in the pics also showed their headers and their over pipe.

They have similar header designs already for other boxer platforms, and this design is really similar. I've just been to the Tomei website and had a good look at the similar headers and boy they look good.

Are you sure the exhaust are "released"? I'm pretty sure that is in end of September. although I hope i'm wrong.

If you read the article they say front pipe will be released at the same time of the exhaust, in September.

Wish they were titanium! But they are still beautiful none the less

I've never come across titanium headers on any car. There must be a reason that they're not suitable.

Iirc it's heat, movement and vibration.

You sure man? the TRD griffon has titanium headers, unless it's a typo or a lie. I think the reason you don't see titanium header is that it's just so expensive, not many people will buy it, hence no point in developing one.

EXACTLY. Greddy made a titanium header for the AE86 a few years ago but it was super expensive

Let's just assume pipe length is similar along with R&D costs if catback is around $1k, header would be around $4k. And that's Tomei, imagine Amuse...

And, moreso than the cost, Greddy are not a top NA-specific brand/tuner; or a top brand. They outsource to China, like HKS etc.

I wouldn't pay top dollar for Greddy.

Tomei/Toda I would. And seeing they've never made a titanium header, is why I question titanium's use as a header.

In terms of is Amuse a N/A specific tuner I don't really know, but if you are talking about top tuner, top dollar Ti headers then it's gotta be Amuse. As to why so little Ti headers, I'm not experienced enough to give you the technical reason. But I do agree with you that there must be a significant reason why as to there are so little. As the members above and I said, an educated guess would be the development and production costs.

^ :coolpics:

To clarify, I wasn't insinuating that I didn't rate Amuse as a top brand, by not mentioning them in the same breath as Toda / Tomei. Amuse have amazing products.

I think super sprint discussed it in their development thread but i can't spot where right now. The titanium alloys aren't suited to the heat cycles a road car sees. They were discussing inconel as a better choice.
@Gardus@Supersprint can you confirm this?

I know. I just mentioned them because they actually have a Ti header and lots of pic to see. A search on google reveals that Ti header for cars are extremely rare, and seeing how the ones that are available are for Evo and S2000, and the custom by TRD. Leads me further to believe Ti headers are just so expensive and hard to make that only the most popular car will be considered and even then it's extremely rare case.

Correct me if im wrong.. amuse use a higher grade titanium than tomei. Amuse use aerospace ssti titanium thats why its cost is much higher?!

The TRD griffon concept has a ti header but it was a projext without budget :/ doubt it will ever come into production.

That's what Amuse claims, but after seeing it in person I have no doubt that is true.

What comes from HKS that's made in China?

Lol, maybe the box the exhaust comes in

Actually TRD Griffon has stainless steel headers and not Titanium. It only has a Titanium mid pipe and exhaust.

Proof?

That was a joke, Im with ya bud. HKS is one of the best if not THE top tuner in Japan. Just look at their demo cars

Maybe u were but I don't think diss7 is

if you look through the forum many members have had HKS exhaust leaked and cracked on them, I think their demo and drift cars are much different than the stuff they mass produce and sell in north america

the "race" headers seem to be all 4-2-1 design. It was hard to see in the pic but now I see the first merge is visible and the second merge happens right before the overpipe. like :)

Stuff in the first post looks like total junk. You'd be mad to buy it.

If that exhaust is priced near the buddy club spec 2 then choosing between the two got alot harder.

*edit* just noticed the exhaust is titanium and will be alot :<

Rather than ask me, ask HKS directly if the product you are enquiring about is made in Japan, or designing in japan.

HKS are one of the common tuners, like Greddy or Cusco. They can make good stuff, they also have had many quality issues. They are far from being classed as one of Japans top quality parts producers, and anyone stating that they are - I guarantee either just doesnt know of better manufacturers, or has never purchased anything from a better manufacturer.

Tomei is going to make a quality product.

I was asking you because you stated they outsource to China. At least up till a couple years ago I know that's 100% false and pretty sure at present time that still stands true. I've actually asked HKS about this. Back when HKS USA was around they did some R&D stateside and some parts came from the US, but those were US specific parts.

Yeah IMO HKS, Cusco, etc aren't top quality stuff like Dome or Mooncraft since they market stuff to the average guys like us. Although like you said they still can produce some good and bad stuff. You have to remember places like Amuse use HKS parts as well.

FINALLLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I wish they would do a dual tip setup, I hate how the twins look with only one exhaust pipe. Guess I won't be buying this :-/

It depends on the titanium alloy used. Some are fine, others need more specialized design considerations.

Interesting, I wonder if Tomei will do an ARMS turbo setup for the 86.

i asked a distributer if amuse would be making a titanium header for the 86 and the response was there were no plans but not because of the material not being able to handle heat but because the cost associtaed with making a titanium header would be way to high for a low cost platform like the 86. I guess companies don't think many people will want to buy a header that cost half as much as the car.

what they are saying is that they can't outsource to china because there isn't enough volume. ;)

I don't see why a Ti header has to be more than 2k USD.

If a catback in 304 runs 500-700 and a Ti catback goes for 1k-2k why would you think the header will be over 4k?

Am I missing something? I mean most people won't spend another 1k just to save 5lbs but I'm sure someone would

i'm not expert but i think it's more material and it's harder to work with i'd imagine cause of all the bends needed for a header. i think titanium is harder to bend

There might be a Ti alloy that can handle the heat, but it probably is crazy expensive.

If you look at Ti exhausts, they aren't bent, they are welded segments, and I'd expect headers to need to be made the same way, meaning Huge labor and costs.

If Ti were a good material for headers, you'd find them on race cars where cost is no issue, and you just don't see Ti headers.

If you want light, you're talking about Inconel.

The front pipe is out!!! :D

Looks like pipe diameter is same as stock.....?
