2k rpm or below and they drone like crazy. But above that theyre just fine.

 

They are one of my personal favorites. They are also Brent's personal favorites. They sound great on the car and drone is not terrible IMO. But when it comes to exhaust note, everyone has a different opinion.

We have put together tons of different exhaust combination's and placed them in our video section for your listening pleasure. A MAC setup is available about midway down the list.

I've had the Mac's on my car since I got it new in Nov. '07 and I love the sound. Like others have said, they drone a bit in the 1.8 to 2K RPM range but if you have a stick shift, it's easy to work around that. Could be a problem with a slush-box, though.
