Here's a clip from a terribly old digital camera (low quality of high quality sound and products) Borla: XR-1 headers, off road x, over axles, and stingers.

I haven't installed the LT's yet. I don't want to put the lt's on and not like the sound. The shorties are safe... When I got them the tech said they were true longtubes but they are mid-lenghts right?

Well JBA reports a noticeable HP gain with the equal length shorties. Mine are off to Jet Hot to be coated today (other post refers). I probably wont get a back to back measurement to see the difference, and it may require a tune to reap the full benefit, but we will see what the G-Tech meter says.

I have heard reports that 07/08 mustangs are having trouble with emission codes that 05/05 mustangs did not in regard to long tubes. In states where you can turn the rear O2's off, there is no issue, but as in NY, some people are having problems. It seems when MIL's are installed that the car now throws a system not ready code. I have seen this in more then one 07/08 mustang (GT and V6), but at the same time have seen 05/06 cars with no cats and such having no issues. And the high flow cats that Kooks/American racing produce flow so well they might as well not be there.

Sure can. Click on the link below titled "soundclip". Its a video taken when my group from Badmustangsclub.com were leaving a car show on LBI in NJ and heading up to the Lighthouse in Barnaget. We had one member who films the shows, head up the road a few miles, to film the cars going by, and to not add any music, but to keep the different exhausts. When you click on the link below, the Grabbers don't have sound, but it will come on. My car comes in around 30 seconds into the video, just after the Mustang that pulled off to the side of the road pulls away. I dropped it down to 3rd, and stood on it half throttle (speed limit was 30 and cops hate people who rev engines down there). Crank the speakers, it sounds SICK!!!

The JBA LTs look great hanging in my garage... >=<

No idea what they sound like yet...

Hopefully next month I can create a sample. I'm in NJ as well, but I just don't care about the **** rules and regulations. In 2011, I'll care a little but more, seeing as I'll need to buy an inspection sticker.

I took a closer look at the stock exhaust manifolds on the GT and they look nothing like the traditional exhaust logs. I compared them with the exhaust logs on the 4.6 2V in the Crown Vic and the GT's manifolds look like a cross between a log and unequal length shorty headers.

I looked through the FSM for several Fords:
03-04 Terminator Cobra
05-06 GT
07 GT500
05-07 S197 GT

They all looked like regular logs except for the S197 GT manifolds. I suppose this is why aftermarket shorty headers don't yield as much hp/tq gains as they once did. I sitll have a set of late 80s OEM Ford Mustang GT manifolds which are really unequal length shorty headers. If Ford didn't see fit to install such headers on the S197, and how they used logs on the GT500 and Ford GT, I'm not sure I want to touch them on the Mustang.

That is because there are not any Long Tube headers that are legal once placed on a street car, weather they inspect and hold you to the letter of the law or not...

As a matter of fact most alterations of intake, exhaust or emissions systems are technically illegal.
