FLOWMASTERS suck!!

[BurningRubber]

actually mac flow really well, better than some straight through mufflers like dynomax

They are at the top of the list for chambered mufflers.

From my experience, if you want loud sound then go with Flows... I ran Flowmasters on my last three 5liter foxes, then i finally got tired of the interior drone, etc.

Magnaflow FTW.

You missed one part. If you want loud than get an o/r pipe and flows.

Flowmasters with CATS is quiet as hell. It almost sounds stock if you dont listen hard enough.
