From what I've read and heard the magnaflows aren't much louder than stock. They are supposed give you a deeper rumble which is nice if you don't like setting off car alarms, scarring the piss out of the prius at the stop light or having a ringing on your ears after long road trips.

You could remove the cats if you haven't already as long as you don't have e-checks. I would suggest going with slp loudmouths if you want to crank up the volume.

Off road or catted midpipe is the answer to this. X or H, doesn't matter - go with whichever one you like better based on sound. Off road (no cats) will be louder than catted, but both will still make a very noticeable increase in sound, plus a nice 10 or so rwhp bump in power. Plenty of clips on Youtube to help you decide.

do you have magnaflow or magna packs? your title confuses me because it contradicts your OP.

if they are magnaflows, go offroad H, and they will scream under wot, if they are magnapacks, go offroad X
