The factory gaskets were reused and were not damaged during the installation. I followed the instructions during install as well. (Torque bolts from center to out).

oh yeah I know what you mean kinda does sound like a exhaust leak. though I checked it out and there werent any leaks

You're not talking about the famous hiss, are you? Because that's normal.

nah the hiss is mostly when you let go of the throttle this is a noise that kinda sounds like water or something like that, its hard to describe it.

I only hear the noise at idle when im standing outside of the car. I can hear it from about ten foot away also. Kinda like a loud exhaust leak. The headers have only been on for about 100 miles so I will most likely retorque the bolts this week just to be sure.

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

XwChriswX · 02-07-2011, 07:46 PM

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.

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.

Mystang Dyno.

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

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

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!

Thanks, Tony
