I've tried e-mailing quite a few different performance shops (buschur, RRE, Mach V, Forced Performance) about the price for just a 3" inlet muffler w/o the catback because I will have all piping done cheaply by local shop. I am looking for Dynomax Ultraflow, or Apex'i N1...but none of the shops have replied. Does anyone know where I can get a good price on just the muffler alone?
