Can you record this so we can see/hear what your talking about?

Tony here are the vids from my run this past Sat. I know the audio sucks on the behind the car shots, next time I'll take them more from the side so not to catch so much pure sound. First 2 pulls are in 4th gear, the last one is in 5th gear, he cuts it off at 6500RPMs and I don't really know why, but oh well...

If you want just the front video's for marketing, let me know I can send them to you if you like.

Final numbers: 283HP/230TQ

So Chris, what's your review of the headers? I'm about to order a set myself, and was wondering if the power gain is noticeable?

Looks: 10/10
Sound: 10/10
Gain: 9/10

Only reason I'm deducting points is cause you do lose some due to ECU compensation, but after getting a tune, which is next for me... you'll gain the full benefit of them.

I would recommend them to anyone looking to fully open up their exhaust. The stock headers on the inside are pretty crappy. But I do notice a good response from the headers. I had my headers and CBE installed at the same time, so I can't say for certain if it's from the headers or CBE. But there is a noticeable gain. :tup:

The only problem I encounter pertaining to ECU compensation seems to be in the 2-3k rpm area where some of the time I will lag a bit as though I need more fuel. Love them otherwise.

Nothing a quick tune won't fix, prob running alil lean. I can't wait to order these headers, need more power & want it to sound louder since I have the 18" resonators.

Let's get them on order! All you need is the deposit money for now and the rest when they ship in 4-7 weeks! :tiphat:

Thanks, Tony

Mystang Dyno.

Kind of, but I was still highest numbers of the day, so it's not a total loss. :tup:

I still need intake and pulleys, then a Tune and hopefully after that I should be right where I want to be. :tup:

Did you have baseline numbers before the Fi install? A set of LTH are definitely next on my list of mods.
