Dont know about magnaflow but for flowmaster, the 40's are loud and have the most rumble. The 50's series have a deeper/muffled sound and you hear them really only when you are on the gas. Look at flowmasters webpage, they have a pretty good diagram that shows the differences in their mufflers.

go with the flowmaster supper 44. Those are kinda hard to find thats why i didn't go with them but if u order them or the muffler shop can get them for u its worth it. They sound great but the flowmaster 40 are awesome too!!!

i have glass packs and it sounds great but i am looking into getting dynomax bullets which are like magnaflows but sound better imo. flowmasters suck also just my opinion i like the sound of just motor like open headers flowmaster just adds rasp and sounds gay. i like very few flowmaster systems. actually they are all on straight 6's which need the extra sound that v 8s dont need

I have a 18" Cherrybomb Glasspack and love the sound. It's not quite as loud as I'd like though. I may step up to a dual exhaust, and flowmasters seem to be the loudest I've heard. Have you looked on youtube yet?

If you like the fart fart fart rappity rappity sound of a glasspack then put that on. If you like the nice rumble of a good sounding exhaust go with flowmaster or magnaflow.

My personal opionion glasspacks should have went away with the 80's and 90's

Let me know at which point you hear "Fart fart rappity rappity"
