Silverline straight pipe?

[Chatham036]

I bought the silverline t304 4 in turbo back single side exhaust for my 6 liter and installed it with muffler intact. My question for you guys is will it sound better, louder, and improve performance if I remove the muffler and install straight pipe? Or does the 6 liter sound poor with this 4" straight pipe set up?

Anyone with videos or sound clips please post

On average the 6.0 will sound awesome with a straight pipe compared to a muffled or catted system but SilverLine's muffler is pretty much a straight through design with hardly any "muffling". I have their system on my '06. At first, I installed it with the muffler on and thought it sounded really good, removed the muffler and put their muffler delete pipe on and it pretty much sounds the same.
