Damn. Either that's a very generous dyno.........or the new GT's have a bit more than Ford's letting on about. Either way, over 300rwhp with just a catback is lightyears better than the 05-09's capabilities.
But isn't the 2010 mustang exactly like the 05-09 mustang just intake/tune? So, wouldn't this mean that we should see the same results if we put the catback into our models?

sounds great kinda confused why a 3" system on an NA 4.6l made more HP I could understand on a fi 4.6 or the 5.4 motor
especially considering its already got 3" exhaust

I thought that the 2010's would about on par with an intake/tune 05-09 also. But no catback has ever pushed an intake/tuned S197 over 300rwhp.....not that I know of. We'd have to do full exhaust with LT's to accomplish this. Either the computer on the new cars is radically different than ours (in a very good way)....or, like I said, this was a very generous dyno.

Very generous...

Ill believe it when I see a 2010 w/ only axel backs run mid 12's...

while Jack was unvieling roush today he quoted stock gt at 350hp so this seems right to me. They are underrating it

It was probably a manual transmission on the dyno. Autos will see the usual lower results.

stock gt 350 FWHP?

Then they must have changed more than just a tune and CAI. Did they change the heads or cam?

I'm looking for a copy of the video now I'll post if I can find.

No way you gain that much from a cat back without putting headers in the equation. maybe 5rwhp............maybe
