that sucks i bet we throw away a hundred a day at work there cheap , i do think the copper gaskets are good to use ,they have a crush factor to them and once they get hot they seal down real good you see alot of people use them on heads becuse they seal so good

Still No resonance, nashua?
If you get them for $400 shipped and have the alignment issues fixed, count me in buddy. Thanks for seeing that this project becomes a reality.
Also, how soon can we expect to get the final production ones? (any estimate)

Sure... NO resonance sound... the BEST advantage so far is there is NO resonance sound.. that made me 
The hole-alignment issue is being addressed as we speak....
I should start taking Pre-Orders this week or by early next week at the latest..
And just to assure you guys that there is no more alignments issues, we are planning on selling a new "sample" headers at cost, to be installed and reviewed and possibly dynoed...!!
How does this sound?

hey i wrecked my TL, but f-it...im in on the groupbuy...damn tell me one thing Nashua, are the headers full stainless steel like comptech or are they plated like OBX...does this issue really matter with headers, plated or full SS...also, why would anyone think about using the stock gaskets...get those rusty things the hell out of there...Shyne

To answer Amir's question i would use the stock gaskets , how many times have you heard a honda or acura have a exhaust leak at the manifold . They only look rusty because the factory uses a cast iron exhaust manifold those gaskets seal up good do you think honda just started building engine's yesterday?

Hello everyone,
I usually read the CL-S forums for the fun of it, especially the black market section for some good deals. Anyways, I am a member af the accordv6.com forums and word got spread about the Stone headers.
My only concern is if the Stone Headers is or will be CARB approved? The only reason I did not get the OBX headers because it is not CARB approved and that their ceramic coating headers look like is made with poor quality.
Comptech on the other hand I would have purchased but it is way to expensive even for a CARB header (although I do thave a comptech exhaust, would be nice to compliment those with the headers.) Therefore I am seeing if there are any good deals for used Comptechs.
If NashuaNightHawk or anyone can tell if these headers will be CARB approved..I am sold...living in California with hi emmissions standards can suck, I do not look forward in changing back to stock just for a smog check (in order to pass visual inspection)

First, thanks for the post and the spreading the word around
At this time the Stone Headers are not CARB approved. You may a CARB waiver. With Those headers you should pass the emissions test.
Maybe someone (EricL) who live in CA can comment.

Stone VS OBX
Hey,
I own a 2001 CLS auto Trans. I only have a Injen intake now but am looking into OBX or Stone headers. The Dyno graphs would not load for me and I was wondering if you could repost them?
I use to tune bike engine's a little bit and have a few pointers for you guys.
1. Remember an engine is just a AIR PUMP.
2. There are a few people who make them but Random Technolgy's claim is that theirs is the best. No matter what anybody says the most restrictive part is the CAT. When you flow from the headers and the 1st restrictiion you hit is that stock CAT it takes alot away from the flow. A change with a Hi Flow CAT would gain the most.
3. Neuspeed also make CAT back system's (MSRP $849) they are very tested. They own a CLS 5 speed with Comptech Super Charger. They are sending me one and my plan is to test with headers ( Stone if I hear correcty that they made more HP than OBX). I am going to use headers, a Hi flow CAT, and Neuspeed exhust. Will Dyno run before and after and then will check Mid to upper RPM for Rich/Lean condition and adjust with something to add or reduce fuel accordingly.
4. I am also hoping to Bore the cylinders with bigger piston's as soon as I can find out how big a can go based on cylinder wall thickness ( this always works and CLS's need Torque BAD).
WHERE CAN I GET THE STONE HEADERS AT A GOOD PRICE?????

the stones would be worth it if they were a perfect fit. 3 people who recently purchased obx's that i know, had no problems installing the headers. By the time you pay a shop to get the stone headers on(assuming they have fitment issues like many have had)those 3 or 4 horses and lb. ft. wont mean anything, especially when you dont feel 3 or 4 horses.

Stone Racing Headers for Accord V6
Hey NashuaNightHawk and All 
I also heard about this on V6p.net and am recently became a member here. I am very interested in getting a set of these for my '02 V6 Accord EX asap. I've got a good amount of mechanical experience and would be handling the install myself. Please let me know what availability will be looking like.
Thanks.

wow, these sound like a pretty good deal. I'd like to get some of these, but I have a first gen. I guess teh obx headers had to be bent slightly to fit the first gen, so wouldn't these require about the same thing? The rear downpipe had to be bed an inch towards teh drivers side for proper clearance for the oil pan in the first gens. If it's as simple as that for these, then I'm in. Can somebody fill me in please?

Plus the CT headers have the nicely ebroidered "Comptech" on them. $500 of that price is probably the name.
