2007 factory exhaust, muffler, resonator

[Joseph Aguda]

Has any consider removing the muffler, adding pipe to fill the void, and leaving the big resonator on thier '07 4.6? I'm guessing it would be pretty loud, but how bad could it be with a single pipe? Any opinons?

the resonator only removes the last of the rumble and tinny sound that the muffler does not. If removing the muffler the resonator is useless.....



Jeff C is running dual straight pipes I know there are sound clips of the 4.0 v6 with straight pipes on here. Probably in his library..

Todd,



I forgot to mention that I have the 4.6. I have the big muffler and a BIG resonator right behing the mufflerwith about four inches of pipe between them. With the 4.6, would your assessment be the same?

 

[Todd Z]

Joe yes... But the 4.6 would be louder...

It looks like they did't use dual exhaust to assure that the Mustang would have more HP.



I would say that with dual exhaust , CAI and a SCT Xcal performance tune 325+ HP would be realistic!

With the xcal tune my 2004 T-Bird ran 0.66 sec faster than before.
