I keep hearing about exhausts exhibiting droning or trumpeting. Can anyone point me in the direction of any sound/video clips that demonstrate these?
I am a real noob so I don't know what sound is being referred to.

I will be adding FRPP Stingers and an X-Pipe soon and I want to know what to expect or what problems I might come across.

Here is a video that show trumpeting. Listen to the 11-12 sec mark.
YouTube - 2005 Mustang GT Kenne Bell Dyno 460 RWHP
Here is one that demonstrates drone:
YouTube - 05 Mustang GT Mac Axle-Back drone from inside the car

Basically trumpeting is a blaring sound you hear during part throttle to wot. It usually happens around 2500 RPMS. Drone is a base like resonance inside the cabin usually when the car is under load like going up a hill and can also happen 1800-2000 for some axlebacks and little higher RPMs for other.

Thanks, now I know. I am hoping the FRPP Stingers will be a good choice for me.

The stingers are one of the best sounding axlebacks, but everyone says the they drone. I have heard the x-pipe helps reduce it a little.

Are there other ways to reduce the drone? Is it a matter of poor installation or poor design?

That's a big can of headache right there It's the design of the stingers combined with the design of rear muffled exhaust along with not enough sound dampening underneath the car and in certain parts inside Just a mess...actually I think Grey Diesel did something to get rid of most of his, but I think it involved a lot of work on his part. You might ask him about it, I think he dynomatted(sound deadener) his trunk and footwells. Like gman said though an X-pipe will help reduce the drone. It seems like H-pipes go well with chambered mufflers(basically a stock setup) and the straight through(like the stingers) go well with X-pipes.
