I'm looking at replacing the resonator to try tame my Bosal exhaust, so I was looking for a shop that sold MagnaFlows. One shop suggested a MAC Performance Flow Path Muffler, said that it out-flowed comparable Flowmaster and Dynomax and should still do a good job of quieting everything down.

It is 4x9x13 with a 2.5 center-in/center-out design. Anyone know if this a good muffler or not?




A user named Stazzie the Australian sells the Magnaflow you seek.

I don't know too much about MAC's, but I do know that Dynomax outflows Flowmaster.
