I picked up a used set of MACs for $200. Now everyonce in while I can swap MACs and SLP LMs every so often. My set-up is somewhat usual: Pypes catted X, 12" resonators and MACs. It's quieter than the SLP LM... No surprise there but louder than stock. Has a nice smooth tone and the drone is not that noticable. I guess the resonators help.

 

Any sound clips? I have the Mac axlebacks and love them, but have considered adding some sort of Catted x-pipe

 

I will try to put sound clips up this weekend.

 

Type in Mustang RAE on you tube. He has vids of his car with bassani catted X and MAC.
