Big Gains from Fabspeed Headers - 997S
Hi All,
Wanted to share with you this dyno chart of a car we recently had in the shop, a bone stock 997S with PSE. We are continuously looking for ways we can improve our products and these latest 997 headers are a testament to that, they are simply awesome and blow X51 headers out of the water. See attached dyno chart below, the gains of 30 ft. lbs & 23 hp to the wheels at 4000 rpm are just from the headers alone.

The above graph is a 997.1 3.8 liter S car. There are very nice gains with the .2's, but the stock exhaust configuration is different, so our 997.2 headers have HJS 200 Cell sport cats incorporated, which increases the price to $2,795.
997.1 Sport headers are $1,695 but we offer a 5% discount to Rennlist members.
The PSE equipped car was slightly louder under full throttle with our sport headers and the rest of the system stock. It did change the note for the better as well.

The dyno runs start at the push of a button, so the procedure is, get the rpms where you want them, push the button to start "sampling", then floor the throttle. The operator just pushed the button at a slightly different rpm, that's all.

Chris, really big gains. I'd imagine many on the board might be skeptical.
5 thru 10 plus hp being a more normal range. Any details on new improvements, tube size and is there consistency across multiple cars. I've viewed your videos and these are well done.

Definitely skeptical. I have your catless x pipe and on your site it says, "Fabspeed X-pipe catbypass will improve low-end torque and mid-range power dramatically."
But I've definitely noticed a dramatic loss in low end torque and every post I've read with those who have your catless x pipe say the same and all of these posts are never responded to. There are even dyno results posted by members showing big losses. I'd be very curious to know how you guys gathered data showing dramatic increases in low end torque with a catless x pipe
Those are indeed amazing numbers just from replacing the headers, but you'll have to forgive me if I'm not completely sold on the integrity of your company

Trust me when I say we were surprised by the results as well. But below is another chart showing multiple stock runs, and multiple runs with headers only. You can see, the gains are consistent.

Color me skeptical also as it simply seems incredulous that a header design alone can yield such results. Especially when reputable competitors pouring the same sort of resources and effort have not produced such results in the 8 years the 997 has been around.
As a point of reference, AWE (whom I think we all agree produce reputable results) only claim 28-31 torque and 28-39 HP at the CRANK with their combo of header/cats/muffler. Your claiming fairly similar numbers at the WHEELS with only a header alone. Something in my mind doesn't add up.
Not saying it's flat out false, but I personally would need more evidence to be convinced.

So let's see the results then, same car, same day, same dyno, your headers vs X51 headers.
Otherwise you can't make such a claim!
So far all you've proved is that your headers perform better than the stock restrictive 3.8 c2s headers in this thread, nowhere have you backed up your claim of them blowing X51 headers out the water, so let's see the results please.

Do you have any pics of the header. I'm curious about the design. Are you using long pipes, is it a Y configuration, 63.5mm pipes or larger? Was the dyno done on a stock car with unaltered ECU plus the header only? What makes it unique/capable of producing such high numbers. What type of dyno are you using? TIA
