I like my Dynomax Cat back with Super Turbo Muffler. Not too loud like Flowmasters can be but still lound and throaty enough for me.

Mine is a 2 1/2 Single Mandrel Bent Cat back.

Dynomax Super Turbos are a really great choice, nice sound, not too loud. If you want louder/deeper sound than go with the Dynomax Ultra Flows. If you have to keep the cat than definitely get a high flow cat. Running any cat will mellow the sound out regardless.

Also, loose the duals and run a single 2.5 - 3" system. A single 2.5" system will outflow any 25 - 3" dual system (it's been dyno proven by others). If you're after the dual look than put a "Y" in.
