Mazdaspeed vs racing beat sound and size

[ottawaP5]

That would be pretty cheap but I don't have the Sedan.


Now that I think about it , its probably worth it to get the entire cat-back.

can someone explain to me why my droning sound happens when i let my foot off the gas only?
for example if i am on the freeway doing 80mph and I let the foot off the gas then i get this droning, if i give it a little gas just to keep the speed constant then the noise goes away.... the droning sound is even worse when I downshift....
