Exhaust upgrade, no drone...

?
remember that resonance eliminator that was on oem exhaust, ford put it there to eliminate drone from 1800-2200 rpms, was behind muffler attatched to piping if memory serves me right...

Here are a video of a 22" magnaflow just installed with a bit of driving
At cruise there is no drone in the cab but while take off you can hear the rumble.

They make it sound a little like the volume of a Diesel, not too loud but you can tell its there. Its Flowmaster's equivalent of the Magnaflow 22". The 70 Series has a 22" body, 5" thick & 10" wide, where as the 40 is 13x4.5x9.75. The 40s are twice as loud.

I have a corsa exhaust for sale which they are known for their unique muffler design that creates no cab drone while delivering more power and better fuel mileage gains through a straight through muffler design. They also have a very nice tone to them that is not loud and obnoxious.
I sent you a pm and e-mail about it. Just let me know.

if youre saying cai systems cant give you better mpg's thats false. they allow your motor to take in more air which lets it work easier which means less fuel used.

I had my '09 done a couple of weeks ago. I told the shop I wanted the 18" but I ended up with teh 14" SIDO through a comedy of errors. It exits in the stock location and the matching spot on the other side. I love it around town but I cannot stand to be in the truck at 70 mph. Tried everything from cruise, no cruise to Leonard Skynard loud and I am swapping it with a 22" SIDO.
I did learn from the Magnflow Rep/Sales guy to the local shop where I am having it done that not all 22" are the same. The part number which escapges me now (ending in 95 I think) is different and has an "X" design inside of it to further reduce drone.
I had a 22" SISO on my '06 and I loved it and it did add some mid range with the CAI. Having it swapped on Monday and will know more then.

The internal x design is on DI/DO mufflers only and is supposed to be for performance, not reduction in drone... although I imagine it would make it quieter in the process. A 22" would be damn near silent to begin with though....
let this thread rest in peace now please lol.

I thought they reduced road noise in the cab a little more in the 09s compared to the real silent 04 - 08 cabs, guess not.

the drone people hear is resonance, sound deadening your back wall helps a lot
