Hey guys, I just wanted to post some technical info and dyno sheets for the Accord V6, TL, and CL headers. Again, these headers are for the automatic transmissions only, and fit the 99-03 TL (ALL) and 01-03 CL (ALL) and 98-02 Accord V6. And the cat back exhaust was fitted on a '99 TL also, so it will fit the 99-03 TL (ALL), 01-03 CL (ALL) and the 98-02 Accord V6.

Below are some specs on the products and the dyno runs on both an
Acura CL and an Accord V6 that has the same engine.

alphawerks fit a six speed yet??

 

Now they have a cat back? Anymore pics of the exhaust?

 

No, I'm sorry but there are no applications yet for the 6 spd.

And Phipark sorry but there are no more pics of the exhaust.

I guess I should chime in here and say that there has always been the cat-back exhaust since day one. It was just never discussed here. But if you want more pictures of the cat back I could bring up some new pics from our site under the Accord V6 dyno...

BTW, in case anyone wants a reference on Excelerate, he is a very reputable vendor and is an authorized distributor for performance products.

Is there still a group buy for these?

 

If six speed headers fit all years and makes, why wouldn't they just make a six speed header?

 

Makes ZERO sense.


The dyno seems about right though. I made the same power, with similar mods, on my car. I never dyno'd with UR pulleys though. Really wish I would have.

 

Is it just my imagination or are the gains higher with the Comptech Headers?

 

Does the dual exhaust fit the CL?

What's the entrance diameter for the mufflers, I think I would change the mufflers out to something less "round," probably magnaflow.

 

Because that extra bend costs money. :ghey: I never understood the concept either.

 

Goldmemberer,

The saying goes, "R+D is in the details." I personally do not know what the numbers are on other headers, I can only speak for the headers that we distribute.

The best thing is that many members of this forum have already dyno'd the product and their numbers back up the performance of the product.

I am confident in the power output because part of our contract as exclusive North American distributors of Alphawerks is that we are required to dyno all their products in a very particular fashion.

Alphawerks requires that all the dynos we display be done at an independent facility in South Florida. The reason for South Florida, is to assure that the product will make power on any USDM car anywhere in the country. These dynos are done in 90+ degree temperatures and at over 100% humidity. In fact when we did our dyno testing on our 350Z headers it was so hot that the car overheated several times in the middle of the dyno runs. It is because the Alphawerks dynos are independent and done under such harsh conditions that Nexus Industry stands behind every single one of those products.

The numbers are nearly identical.

 

what kind of warranty on these headers? and where are they made?

 

Here's a link for the AW exhaust.

how much can the catbacks be bought for?

BTW nexusindustries i have the AW headers, and they're absolutely great.

 

Warranty on the header and all associated components is 1-year

 

For all questions on purchases including group buys please refer to Excelerate...he is an official vendor on Acura-cl.com...we are here primarily to give any tech support and answer as many of your questions as possible in as prompt a manner possible.

Props on the dyno. Who's accord is that?

 

That Accord actually belongs to our in-house accountant/book-keeper. The funny thing is that it is a she and not a he. We needed a V6 to dyno test and so we grabbed her car 100% stock and took it to the dyno, installed the header and dual cat-back exhaust, and strapped it on the dyno w/in like 90 minutes of the orginal baseline run and got the +34bhp and +26lbs/tq. to the wheels. We were really happy with the numbers considering the dynos were done in South Florida in the summer when it was averaging like 97 everyday and 100% humidity...

 

Josh did the headers come in yet?

 

so why arent there 6-speed headers?

 

Here's my little review.

I've had the AW headers for quite some time now (4 months) and they were installed by an Acura mechanic.

I've had resonance problems since the week after he installed them. I thought it was the tranny that was making that noise, so I took it in and they put a new tranny in, but the noise comes from the Y-Pipe. The mechanic retorqued everything but it didn't help. Also, it had a little leak where it connects to the exhaust, but it wasn't too bad.

Just letting everyone know before buying these.

Price vs Power, these are the best thing you can get for this car performancewise. If it wasn't for the resonance, I would pay double for these if that's how much they cost.

 

i'm surprised, i believe that this is first time i've heard of resonance with the AW headers.

 

That's suprising because we got them from the same place.

Also, the mechanic who installed and retorqued them is actually a member on this board.

 

and these will fit like the OBX's with bending for the first gens?

page 2 = mines biatchs

 

I feel you on the resonance, I have the Stone headers and the same issue. Im probably the only one that can or ever will tell, but durring some slow to moderate acceleration, you can hear it right around 2500 rpm. I wonder why that is? Or anything that can really be done about it?

 

Exactly, only mine is at 1700 rpms. The only reason why I thought it was the torque converter at first is becase it won't do it when the car is in park. Only when it's in motion do you hear it. It's not something you notice right away, but it becomes really annoying after a while, especially at low rpm highway speeds.

BTW, the mechanic's name on thsi board who installed them is AkuraTek. I'm sure he can tell you guys more where exactly it's coming from.

 

Sorry for the delay on the answer but yes the groupbuy is still active. See my signature for a link.

Rezurex shoot me a PM and we can talk pricing on the catback exhausts.

Actually yes they did. I received my shipment of V6 headers and other headers/exhausts for the Civic/Integra/Accord yesterday. All prepaid shipments will be going out soon.

Finally someone to compete with Comptech on their B-pipe application.

 

Someone wanted closeups and more pics of the exhaust system...see below...got them from one of our distributors website...remember Accord V6 is same system.

PS...thanks Sam at wheelsnext.com for the pics

 

 

Car_lost,

I am going to take a stab in the dark here and say that you have a 6-speed. If you do have such a model would you be interested in a sponsorship that would be mutally beneficial to both of us? We need a 6-speed to test fit because the part was developed off an auto tranny. Please let me know what the case is...just PM me...

 

i dont have a 6-speed. its just that many people have asked this question with no response. especially when it makes 100% sense to make them instead of the auto ones. the 6-speed headers have a slight bend in them in order to fit the 6-speeds. along with fitting the 6-speeds, they fit the regualr automatics just as well.

there are quite a few florida members that have a 6-speed though so im sure it wont be THAT much trouble to get one. the first that comes to mind is fuzzy03cls, if he is not interested, then i guess make a thread asking for one.

 

Would that mid-pipe work with comptech axleback exhausts? (2000 TL) I assume it's a high flow cat? Thanks

 

What "R+D" did you all actually do? How do your headers differ from the ones Comptech has offered for years, besides price? they look identical to me.






Also those mufflers really don't do it for me at all. They look ricey, like coffee cans. I don't think they'd look good on a CL, maybe on the Accord, but not on our cars IMHO.

 

You really need to stop driving the cars into the ocean. As that would be about the only way to get greater than 100% RH.
