Magnaflow, Flowmaster, and Sibling Rivalry

Growing up in the 90’s, I was exposed to such quality entertainment as Home Improvement.  My brother and I couldn’t get enough of it. We could sit there and watch Tim Allen’s hilarious antics for hours. Throughout the years, Tim the “tool man” Taylor was always building a hot rod in his garage, which probably sparked our interest in cars--  that, and our undying need to be in competition with each other.  As soon as we got our licenses we fought over “car rights” non stop, since we had to borrow our parents'.  We worked hard and saved up enough to buy our own cars.  I only had a few grand, but wanted something fast, so I bought a 93 Mustang 5.0 coupe.  Sure enough, my brother bought a 1992 Mustang LX 5.0 Convertible; always trying to upstage me.  He can have fun in the sun, but I’m going to be the one burning him every night at the drag strip.  His flashy style has always gotten the best of him.  He would rather roll up in a convertible with rims than have a rocket under the hood.A few weeks ago a pulled up next to another 5.0 Mustang and looked over at the driver.  Our eyes met, knowing what would happen when the light flashed green.  I revved my engine a few times and glanced over at him, only to find him laughing.  Of course I wasn’t too happy with this and mumbled some words under my breath.  He responded by slowing revving up his engine, letting out a deep growl.  The light turned green and I slammed on the gas, immediately taking the lead.  He hesitated then took off down the road, blasting right by me.  Man, I need a new exhaust.I started by checking some Mustang enthusiasts' websites and found a pretty heated discussion about mufflers.  Apparently choosing a Magnaflow or Flowmaster muffler is like joining the bloods or the crypts.  After reading a bunch of posts, some useful some not, I found that the people generally chose the Magnaflow for power and the Flowmaster for sound.  Like I said, I’m interested in one thing—going fast.
