Today was the last straw.. I was sitting idling in a parking lot eating my junk food lunch, when a woman came out of the building across the way and asked me to shut my engine off. According to her my car was "very loud" idling in the parking lot.
I'm running an OEM 04-05 STi muffler, so suggestions like Borla Hush won't really be helpful. I'm fairly certain the hush will be quite a bit louder than what it is right now. I am also highly opposed to anything that will hinder exhaust flow/performance. My idea is to measure the longest straight section of pipe in my catback and install the longest resonator I can fit.
Any other ideas?
