I just installed my MAC axle back mufflers and their almost perfect.

The only draw back is the drone below 2000 RPM in fifth gear.
There is no paint can rattle, snap crackle and pop or gurgling all of which I hate and have heard in other systems. Just a deep throaty smooth sound. I am happy

The GTAs don't have a drone and sound great also.

Deep and throaty, american muscle sound! I'm glad it sounds awesome!

[stlwagon]

The MAC drone is fairly well documented.

[POCO]

I liked the Mac's(4-sale) but I wanted a more violent sound and settled for the Spin-Tech axle back's.My nieghbors hate me at 3:00A.M. in the morning

true american sound
immm plannin on gettin magna flows tho but not to sure

Once they burn in a bit the drone will minimize a tad. It's always there in that range but to be honest I don't even hear it any more. If I do then I'll just downshift or speed up a bit as it's a narrow range where the drone is.

MAC's are awesome!

I have always been partial to flowmaster.

I had mustangs for the past 12 years and have tried others.

But keep going back to the classic sound of the flowmasters.

+1 on the MAC's. I still love mine.

[Bman08]

I loved the MAC's I had on my car before I installed LT's. I still think the MACs sounded better with the LT's but I couldn't stand the increased drone. If I had a stock mustang again, I wouldn't hesitate to put them back on.

[hotshot]

the drone is common but just keep it going at 2,500 rpms
