I have the exact same setup as you named and I like it. It isn't very loud but its toned and deep. I am awaiting catless down pipes which will make it a little louder. If you don't plan on doing anything else to the exhaust then just do a muffler delete. When I put my mufflers on I started it with no mufflers and it sounded really good, I almost left it that way. The only reason I didn't is b/c I knew it would be too loud when I put catless downpipes on it. If you don't plan on getting catless downpipes then your biggest bang for your buck is getting cyba tips and doing a muffler delete.
I have exhaust and an intake...
