Default Re: Quiet -- stock like sound level -- turbo back exhaust

I put the stock catback on my car with the catless downpipe, and I honestly think it is slightly quieter than stock (in-cabin noise. Pretty sure its louder outside). There is less bass/boom to it. Highway drone is almost non-existent. I'm kinda thinking about adding a Nameless resonated midpipe and keeping the stock mufflers to see how that does.
