Nice!!!

I'm wondering why not made them D port anymore.

LS7 heads are D port.

Congrat's on being the FIRST header manufacturer to finally "get it" and offer a 3-1/2" merge collector for our beloved C6Z LS7!!! You should seriously consider this as an option for your 1-7/8" stepped headers (since that's where the bulk of your market is and where you'll make the most $$$) and at least offer them as a custom option...just a thought to once again stay "Industry Leading" and watch the competition follow
D-port matching headers are a myth and round makes more power!

Unless someone proof me that D port are useless with a LS7 dyno sheet I will continue to belive in that myth.

What kind of improvement of the ARH 2" setup that I already have for an 8xx whp setup?

The 1 7/8" ARHeaders are Dport.

2" and beyond are round port.

Looking nice!!!

You're out in Deer Park? Use to waste alot of gas up and down Route 231 back in the day.

Some good times back then.

Congrats with the new Headers. Will be interested to see how much more they allow in a 1/1 swap, and then how much more tuned.

Sébast19X

2'' and beyond should be also D port.

(BTW I have a 2'' D port probably the last one made by ARH and the gain are noticeable over the 1 7/8)

Thx

I think they should just be round.

So many different theories and opinions when it comes to headers....

AR Headers

Seb, We were the first to use D-port flanges for the LS7 cylinder head back in January 2006. When we first released 2" headers we went with D-port flanges but we knew it wasn't necessary based on what we've learned thru testing with a variety of applications. Not blocking the port is what is most critical. Your typical 1-7/8" round LS1 flange may block the port which prompted us to offer the raised D-port flange. There is absolutely nothing wrong with running 2" round port flanges on LS7 heads. There is no power disadvantage whatsoever. Hope that clears things up.

Ok

Fran@Race Proven has the first set on a Z06.

Overkill for a high compression (E85) setup? I've got Kooks 1 7/8" and pondering going to 2" but wondering if i'll really realize any gains.

Undy

I don't care what anyone says. I'd have to see comparative independent dyno runs to believe otherwise (like that's really going to happen).

SteveDoten@ARH

Are you over 700-750whp? If Nick(Unreal in Tempe) is your tuner, best bet is to ask him.

We've listened to feedback and testing from numerous high level sources in Michigan.

Ask anyone who has experience with 427ish or larger motors.

With was a flowing close to 400cfm or more..

Ask them what size header they wools recommend.


The headers posted here are a lot closer to that recommendation than anything else on the market.

Especially when compared to the stuff
Most of us run.

These headers look killer. Don't underestimate how important the right set of headers are. Great job ARH.
I have a stepped header system built by ARH made for my 396ci 1000fwhp race motor and they working great on my 346 ci 470whp SBE ls6 motor.
