So I have a 2010 GT with Flowmasters... love the sound but HATE the drone at 1700-2000 RPM.
I was thinking... what if I installed resonators further up the exhaust - staggered as to alter the sound waves enough; would it eliminate the drone? What about the possibility of installing a resonator on 1 side of the exhaust, only? What are the opinions out there? What are the chances that theres a sound engineer out there in Mustang Forums land?
Thanks in advance for your input.

More FRPP Borla Stingers drone in the same RPM range. I shift out of it or DRIVE out of it ("Sorry officer, but I was speeding because my exhaust drones at the PSL..."). I live it and my wife actually likes it.
I've heard that offsetting the mufflers helps but I'm not sure how that works with axlebacks. Have you checked with a local speed shop?

What Flowmaster's do you have. I had an '09 w/ Pype's Violators. No drone what so ever. Chambered / baffled mufflers will give you the dreaded drone you are talking about. The Pype's where a louvered tube like the OEM only with a larger tube, and larger louvers. They were reasonalbly priced and gave a much better sound than the OEM. Not sure what to call the type of muffler them OEM unit is called. Nuke?

I think doing a mid-mounted offset muffler like the Borlas will get rid of the drone (using this in conjunction with the Flows). Pretty sure you can also just do the mid-mount setup without axle-backs (just tips), but not sure about how loud that would be. There's some stuff on YouTube.

Corsa on the Mustang however has NO drone, even with the O/R pipe!

Chambered style mufflers are not the cause of drone, its the positioning of the mufflers from the engine, pipe diameters, location of the tail pipes, and a few other things. Even if a sound engineer was to join in, there isn't enough info to actually calculate what you need.
Your resonator idea is probably the best bet. I'd put it on both sides , probably about a 3" offset in the spacing. What kind of flowmaster's are you using? A higher quality axleback would also help, you're going to pay 100-150 to get the resonators installed most likely.
