Options to make lt headers quieter

I want to buy some headers for my supercharged truck. I had some ordered from urd last fall and was sent the wrong ones and ended up with the shipping guy lying to me but now I'm over it and saw they have the right ones in stock. But now after having y pipe and urd 3" cat back, I really like the tone but also would like more power and I'm concerned about how loud it will be with headers. I know headers will be louder no matter what but I'm wondering if there's a quieter muffler or some way to make it about the same tone I have now which I really like. I saw gadget had put another muffler on his xrunner and he said it made a pretty good difference but I'm not sure if I want to go that route. So has anyone tried just one muffler to make it more mellow or something else close to it?

 

This is what I'm going to use once I get a set of URD's tuned long tubes. Just have an exhaust shop weld it in just in front of the muffler on that straight section plenty of room there for it to fit. Theres a few guys on the forum using these as well with good results.

Will that rob much power from the exhaust?

 

No you should be just fine.
