Ok now I have found someone talking about what I need to know, I want to know if my factory tune with my Airaid CAI would benifit with axcel back performance muflers without making droning while I go down the highway at 75?

[RyanHNT]

will I get gains with my stock tune and Airaid CAI or will I be wasting my money with a performance muffler?

FYI, i just swapped a different intake onto mine, and because the EEC is adaptive, i've had zero problems and it makes noticeably more power than before.

both sides are true and i belevei can explain some of it.


its called the venturi effect. here is how it works. say we have a certain amount of air flowing throught our exhaust. if the diameter decreases the velocity will increase and the pressure will decrease. on the other hand if the diameter increases the velocity will decrease and the pressure will increase.

hope that help you guys.

+1 i was about to say the same thing! simply put the big the diameter the slower the exhaust goes (i think the chart was for a stock mustang untuned) but both sides are right! great post guys
