Best way to quiet down the OBX cat-back?

Hey guys,
Installed my new OBX system this weekend, overall I am very happy with it. The fit and finish of the product is outstanding. I do like the tone of the exhuast note, but unforunatly it is about 10-15db too loud for my tastes. Note that I do have intake and ypipe so that will add to it. Currently I am looking at having a longer and bigger resonator/glasspack, 26inX4in with a 2.15in core, welded in.
Can anyone recommned any alternative to this? Has anyone else tried to quiet down an aftermaket system that can give me any advice?

Thanks.

Do you loose any HP from the resonator? I want to put on a cat back and keep the stock muffler but also want a little growl. Any ideas?

Like an airplane. I'm pretty sure your WOT db level is around 130-140. Idle around 105-115.

I'm still legal

"after reviewing the play"(24 hr testdrive) my budget b came with a nice big resonator- no backpressure/dronnin inside cabin where it sounds stock- but during acceleration my 6 speed sounds like (350z/fx45) in sound- oh and muffler is stock

the resonator def will bring the noise level down!
