Does Flowmaster make both American Thunder & Deltaflow 40 kits for 05 GT?

Dumb question...

Does Flowmaster make both American Thunder & Deltaflow Series 40 axle-back kits for the 05 and up GT? I've see conflicting posts on this and other sites. The Flowmaster site didn't help (for me, at least).

Thanks.

Is this one American Thunder (AM) or Deltaflow (DF)?

or did they design one system that is specific to the 05GT & they don't call it either AM or DF?

I have the American Thunder Kit, and as far as I know, that is the only kit made for the '05. However, I think you can still buy Delta 40 mufflers separately but then you would have the old resonance problem around 2,000 RPM.

Yes they do sell the Flowmaster catback for the 05's.
It not only makes your 05 sound good but,it's a great
upgrade for your 05 as well.:thumbsup
