Are they straight thru/turbo style ?

 

Almost every aftermarket axleback has exhibited drone from what I could hear. The only ones that didn't do it are stock, GTA, and Corsa. Magnaflow has always droned from experience, but I'd like to know what exact configuration you have where the Magnaflows were drone-free.

 

The maggies are definitely deep sounding and have zero drone. My only complaint is they're very quiet from in the car. I guess it depends on what you want. Down the highway with long tubes, cats and Maggies it's only slightly louder than stock. Very smooth and deep sound though. Good for a daily driver.
