exhaust question (not in exhaust faq)

[sd88supra]

ive been reading up on mufflers and i was aiming to get a flowmaster 40 which apparently aren't straight thru design. straight thru design i guess is best (helps increase exhaust speed). i was thinking of going with flowmaster for a deep tone (i hate fart can rice mufflers), but how does the tone and volume (and performance) of a flowmaster compare with a magnaflow? a lot of magnaflow guys tell me flowmasters are nothing but name and are better suited for american muscle cars. if the sound is too loud i suppose i could add a resonator (as mrnickleye did). and i remember isphius saying he didn't like his magnaflow... open to suggestions/opinions
