flowmasters or dynomax?

Which mufflers hould i get the flowmasters that the guy in the multimedia section of this site has or the dynomax which i hear sound good on gp's but the flowmasters on this site sound good also. Does anyone have any sound files of dynomax mufflers on gp's? Which of the 2 flowmasters o dynomax,i want good perrmance flow and a deep nice tone
thanks

I HAVE THE DYNOMAX SYSTEM.AFTER LISTENINGTO ALL THE AVAILABLE SYSTEMS-MUFFLERS I BELIEVE THIS IS THE BEST AS FAR AS MELLOW DEEP SOUND WITHOUT BEING ANNOYING ON THE HIGHWAY

i will agree with AcsAuto. I love the Dynomax on our cars. My friend has it on his GTP. Sounds great but not to loud cruizin down the highway. I have no muffler just cat and resonator...its loud but has a nice low tone at idle and cruizin. but i have considered put something on it to tone it down....i dunno yet. i get a lotta comp's on the sound and it turns heads so i dunno its all about pref..

Just to confuse everyone a little more, Magnaflow makes a performance muffler that I have used on a couple of cars. Sounded great, but I haven't heard it on a GP. I had a pair of Dynomax's on a Corvette and didn't think they lasted very long. Sounded good though.
