Well I had a sticky on most of the popular types and brands of mufflers out there, But what Charles said is true choose the sound you want. Actually if your car is stock or near stock the perfromance gains are minimal. the deference being 1-2 hp difference brands. If you want the loudest mufflers go with glass packs or chambered mufflers like Flowmaster, MAC Flowpath or spintech. If you want best flowing get a flowthru design muffler. The most popular being Dynomax Ultra flows, Borla's or Magnaflows they have good sound just not quite as loud.
