The Nameless deletes are insanely loud while highway driving. You have to remember, the Outback is essentially one giant bass tube. I started out with the deletes....my neighbors hated me, and my wife refused to ride in the car. Then I went to the 5" muffs, and they were amazing. Nice smooth sound from the EZ30. Then I went too far, and got the car ready for a supercharger, and put on Raptor headers, with a full custom header back exhaust with high flow cats. The rasp was so unbearable, that it shook the headliner......so I switched over to a set of AVO mufflers. Deep tone, but anything over 20mph was like death. Finally, I threw on a set of new OEM muffs, and welded in a Vibrant ultra quiet resonator. Nice and quiet, with a little blurble if I get on it. If I could do it all over again, I'd go with the Nameless 5", and do some major sound deadening. A nice set of OEM STI quads would look great, but that would require a lot of work making them fit. @imprezkid did it, and it looks great, but alot of work.
