Is the Shelby American Motorsports new?

I wanted to have the 3" JBA optional Super Snake exhaust installed on my Super Snake while my car was out in Las Vegas in late 2008/early 2009, but I was told that the car would have to be sent, by me, to JBA for the exhaust add, after the conversion was completed.

and I still think it is a great exhaust to be put on the Super Snake. It makes a Super Snake sound like what I think a Super Snake should sound like and I hope JBA comes out very soon with a header/exhaust system for 2011+ GT500s. They already made an exhaust system for the 2011+ 5.0 and I am dying to hear them on the aluminum block(unless the iron block JBA system can be fitted and tune on the new 5.4). It also would sound aggressive with ARH headers and magnaflow cat-back.

I see stainless long tube headers listed in the above discription. With the exhaust change ahead of the catback, is this car/package still 50 state emissions legal including California?

Our speed shop ugraded power packages are not 50 State legal………………….  Never have, Never will be. BUT they are legal in states that have not ADOPTED GREEN state emissions laws. All of our standard build packages, base Super Snake, GT 350 are 50 state emissions legal. When it goes to the speed shop for upgraded power packages this is not true. They are, however, designed to run on 91 octane pump gas through 900 crank rated gross HP.

ARH, off road x and Borla Stingers are pretty nasty sounding.

Thank you Roger,
yes this is true as our "Holeshot" package which contains Cams, Headers, X-pipes, rear suspension work and calibration is not 50 state legal and anyone calling us on this type of build is told this and or asked about the state there calling from. Also all of our package numbers are CRANK numbers not rear wheel horsepower! All 605,660,725,750,and 800hp that have come out of production are crank rated hp numbers. We have seen gains up to 100hp with our KenneBell 800hp package so we can accurately state a 900hp build.

Keep in mind and i want to make myself very clear on this issue, the REAR WHEEL HORSEPOWER numbers are different on every vehicle! There are several factors to concider when dealing with this topic... the factory horsepower from the dealership will vary between cars as it is a proven fact. Elevation, temperture, humidity and variations in octane and boost levels will drastically affect the outcome of a "rear wheel" horsepower number during dyno testing. Therefore we never sell or state a rear wheel number to go by as this would be unfair to us and the potencial client. We would like to appologies if this was in anyway unclear or misrepresented in the past or previous posts. We strive here at SAM to meet or exceed you HP goals!

Thank you!

That too along with either magnaflows, Bassani competitions(if they are not too loud) or Alex's MAC MMS mufflers.

Also a Borla full exhaust with headers, off road x and Borla Stingers sounds pretty mean too.
It's also kinda funny because it's the same car on different youtube channels

900 HP. Now 1,000 HP.  That is insane! But isn't it great to be crazy...
