2005 Mustang GT... Installed MAC axle back exhaust

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.

The MAC drone is fairly well documented.

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.

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.

When I had macs they didn't drone that bad. They were a nice axleback but they weren't loud enough.

Easy solution to the drone...floor it everywhere you go! Never let up on the gas! Nah, man I wish I knew the sound of my SLP's though. One more month and I will, I can't freaking wait.

I have had the MAC Boomtubes on my 06 GT auto for about 8 months now and love them. The drone is there but I kind of like it (wife hates it). I leave for work at 5:30am every day and the neighbors don't like them much! They do break in a bit over time but the drone is still there. At 80MPH around 2600 RPMs you can hear them but it's not bad, just crank the radio! Easy install also.
