your right. Here is the link for a dyno done by drift office with the Rev UEL and other exhaust parts:

and here is the dyno for Revworks tuned by Drift Office on 90 something gas

here is a dyno comparing the OFT + OPH combo

compare those tq dips. Which one looks better?

max horse power from the Revworks is lower at 174.89 when compared to OpenFlash setup at 190. But, max power may not be the most important stat for many drivers. What about the differences in tq dip? The dip in the Revworks looks more smooth to me.


Shiv's dyno is a better example of what his gear can really yield because of the several dyno runs overlapped.

The Revworks dyno is older and their is only 1 dyno in this example for review. This may not be the best representation of the Revworks header.

Nonetheless, that near elimination of the tq dip at the cost of max hp is really nice. A selling point to some. Maybe me.

Now, JDL has come into discussion and it is a gorgeous piece equipped with flex joints and a lifetime warranty. They have a dyno posted on their site showing nice gains but that's E85. I havn't seen 90 octane dynos for comparison. Price for the JDL shipped to me is around $920, Revworks, $710 and OFH $600.

decisions!!

They are on sale for $859 now too!

I thought the JDL warranty was lifetime vice 1yr....

it is it is! typo on my part.

Thanks for considering our Product in your next purchase! We know there are ton's of options out there now for header choices, but i encourage you to message us if there are any unanswered questions you may have! We are proud to say that we have now sold over 100+ headers, and that every single one has still been made in house by our hands! I personally inspect each one before boxing and shipping to our customers.

Let me know if there is anything i can do to help!

People get too hung up on the american made thing. I've bought plenty of stuff from the US that sucks.

OFH

i got a revworks before the ofh came out. its a solid item but my flange was warpped and leaked. they offer one yr replacement but doing the work twice again and packaging this big item is quite a job

That dyno chart looks like its from an earlier map release. Did you happen to see the one that shiv posted in this thread? The one with E85 shows literally no torque dip.. mmm got to love that corn juice!

I went with Revworks. good price excellent quality and proven gains. JDL is nice too but its more money and i doubt gains will be relevant if any. i'd love to see an unbiased back to back comparisson between the two tho.

scaling is different, just FYI. Its slightly to RevWorks favor (stretched out a little more) if I'm looking at it right. So the tq dip will look worse for the OFH if you're comparing just those two dyno charts.

I went OFH and should be in one of the early batches so hopefully I'll be able to report back in the next month or so.

Customer service was important to me, and while I'm sure RevWorks is awesome, I had personal positive experience with the OpenFlash guys.

Really I'm sure you'll be happy with any of these -- can't argue with JDL for quality, and OFH for price, and I'm not sure where RevWorks falls since I don't have much experience with them. I'm sure they're great too :)

The guys at open flash are pretty awesome

There are several dynos of both headers out there, third party. Granted it's not a blowout difference between them both, but I believe tuners can squeeze more HP out of the JDL vs the Revworks due to the design/collector on the JDL.

I've been super on the fence about which of these three headers to pick. What has helped me make up my mind is the dyno evidence. The fact that if you look through almost any thread discussing these headers, Shiv is up in there somewhere with his dyno charts. I'm not saying these other guys don't have graphs but as others have stated the scaling is different favoring the other header. As well as there is just way more dyno charts of the OFH on all kinds of set ups. Seems to me Shiv is the only one not afraid to throw his dynos up anywhere. Winner.
