I had an Blitz nurspec muffler on my sti from when I bought it. I eventually got sick of how loud it was especially crusing at 100kmph+ Don't get me wrong it was one awesome sounding muffler you could hear from the next suburb. Did some research and ending up getting an AVO oval muffler. Cut the blitz cannon off and swapped them. The AVO is much quieter yet still has a good note. Highly recommend it.
