Thanks for the info, I wonder if you can re-install the two mufflers should you decide to return the Magnaflow back to original or did you cut them off flush to the muffler.
I heard the sound with the 4" tips. I'm doing a Spartan cam install this coming weekend and have been told that the cam will make for some better more aggressive sound. Will wait to see if that's the case. If not I will modify my Magnaflow setup or replace it with a JBA system as I have JBA Shorties and catless mid pipes. Are you running catless and headers?
