Looks like it. At least the four inch tips. Maybe the chambering is different?

I saw some close up pics of the exhaust. Can't remember if it was taken from someone at a car show or a press release pic but it looked like the tips were 4" BUT only for decoration. You could see the actual exhaust further inside and it was a bit smaller. Didn't look too great but at least with the baffles out of the side exhausts it should be a good sounding system. I'm crossing my fingers.

In the Jay Leno video it sounded sick. I imagine it will be even better once you pull the discs.

The under car pics also show prototype tags on the mufflers. I could be wrong, but to me this would indicate Boss-specific mufflers.

I'm planning on installing electric dump valves, but the stock discs look to be 2 bolt and everything I have been able to find on the market is 3 bolt. Does anyone know of a manufacturer making a 2 bolt or am I going to have to ge new flanges welded on?

The muffler internals are the same as the GT's, with a larger tip added.

As stated...same as GT's just different tips. BTW check the vids that S197 has on youtube...obviously VERY close to the Boss or S197 development program, or has a CLOSE friendship with the Ford development engineers

Here's a photo of inside the tip I took yesterday. This is on the black LS that Parnelli Jones signed.

Those are pre-production (incorrect) parts shown in the picture. The production tip is similar to the 2011 GT automatic with a 4" tip welded over the 2.5" outlet pipe (for appearance). To meet exterior noise requirements, tailpipe sound has to be slightly reduced to allow room for the additional sound that comes from the sidepipes. That's why the big, full-size 4" tip is not used in production on the Boss. Hope this clears it up.

Thanks, I saw a photo of something similar and was hoping that was not what was going to happen on the Boss. Is that why the GT500 mufflers aren't being used because it would be too loud?
