Finally bought a WRB 03 WRX and couldn't be happier. It is completely stock except for an up pipe, down pipe, and fast motors ports 3" exhaust. Needless to say it is a little loud for my taste and my wife hit the floor why she heard it. I've been researching the best way to quiet it down while keeping the performance. I've heard good things about the borla hush and megan racing mufflers while others say adding a resonator would be best. Is it bad to have a 3" full exhaust tapered down to a muffler with a 2.5" inlet? I'm hoping to get some insight from you more experienced Subaru owners out there for the best way to get quieter int he most cost effective way possible.
